7783-70-2 Usage

Chemical Properties

Antimony pentafluoride is a noncombustible, oily, colorless liquid with a pungent odor.

Physical properties

Colorless oily liquid; highly viscous; hygroscopic; freezes at 8.3°C; boils at 149.5°C; density 2.99 g/cm3 at 23°C; soluble in excess water (with violent reaction) and glacial acetic acid; also soluble in potassium fluoride.

Uses

Different sources of media describe the Uses of 7783-70-2 differently. You can refer to the following data:
1. HF/SbF5 is an excellent medium for the preparation of alkylidene oxonium salts.1
2. In the fluorination of organic Compounds, see the monograph Preparation, Properties and Technology of Fluorine and Organic Fluoro Compounds, C. Slesser, S. R. Schram, Eds. (McGraw-Hill, New York, 1951) 868 pp.

Preparation

Antimony pentafluoride is prepared by the reaction of antimony pentachloride with anhydrous hydrogen fluoride:SbCl5 +5 HF → SbF5 +5 HClIt may also be prepared from antimony trifluoride and fluorine, or by treating antimony pentaoxide with aqueous hydrofluoric acid and evaporing water.

General Description

A colorless, oily liquid. Fumes irritate the eyes and mucous membranes. Toxic. Corrosive to metals and tissue. Extremely dangerous to tissue; its burns may be followed by gangrene. Only shipped in cylinders. Under prolonged exposure to heat cylinders may violently rupture and rocket. Used to make other chemicals as well as a catalyst in the manufacture of other chemicals.

Reactivity Profile

ANTIMONY PENTAFLUORIDE is strongly acidic. Reacts vigorously with bases. When heated to decomposition, ANTIMONY PENTAFLUORIDE emits highly toxic fumes of fluorides and metallic antimony. Reacts with ammonia to form a diammoniate.

Hazard

Corrosive to skin and tissue.

Health Hazard

The compound is irritating to eyes, skin, and lungs. Contact with eyes or skin causes severe burns. The compound is extremely toxic with a probable oral lethal dose of 5-50 mg/kg or between 7 drops and one teaspoonful for a 150 pound person (antimony salts).

Fire Hazard

Reacts violently with water, to form poisonous hydrogen fluoride fumes. If confined and wet can cause explosion. May cause fire in contact with combustible material. Hazardous polymerization may not occur.

Safety Profile

A poison by inhalation. A very reactive, corrosive liquid to skin, eyes, mucous membranes. See also FLUORIDES and ANTIMONY COMPOUNDS. Violent reaction with phosphates. When heated to decomposition it emits very toxic fumes of F and Sb.

Potential Exposure

It is used as a catalyst in chemical reactions or as a source of fluorine (fluorinating reagent) in fluorination reactions.

Shipping

UN1732 Antimony pentafluoride, Hazard class: 8; Labels: 8-Corrosive material, 6.1-Poisonous materials.

Purification Methods

Purify it by vacuum distillation, preferably in a quartz apparatus, and store it in quartz or aluminum bottles. It is a hygroscopic viscous liquid which reacts violently with H2O and is hydrolysed by alkalis. It is POISONOUS and attacks the skin. [Woolf & Greenwood J Chem Soc 2200 1950, Kwasnik in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 200 1965.]

Incompatibilities

Water and other forms of moisture releases hydrofluoric acid, combustible organic and siliceous materials, phosphorus, and phosphate materials. Attacks glass, ceramic, lead, and metals, including copper in the presence of moisture. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Antimony pentafluoride, if confined and wet may cause explosion. Antimony pentafluoride appears to have oxidizing properties; may cause fire in contact with combustible or organic materials. May react with metals, including lead, releasing flammable hydrogen gas.

Check Digit Verification of cas no

The CAS Registry Mumber 7783-70-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7783-70:
(6*7)+(5*7)+(4*8)+(3*3)+(2*7)+(1*0)=132
132 % 10 = 2
So 7783-70-2 is a valid CAS Registry Number.

Solid-State Structure of Protonated Ketones and Aldehydes

Stuart, Daniel,Wetmore, Stacey D.,Gerken, Michael

, p. 16380 - 16384 (2017)

Protonated carbonyl compounds have been invoked as intermediates in many acid-catalyzed organic reactions. To gain key structural and electronic data about such intermediates, oxonium salts derived from five representative examples of ketones and aldehydes are synthesized in the solid state, and characterized by X-ray crystallography and Raman spectroscopy for the first time. DFT calculations were carried out on the cations in the gas phase. Whereas an equimolar reaction of the carbonyl compounds, acetone, cyclopentanone, adamantanone, and acetaldehyde, with SbF5 in anhydrous HF yielded mononuclear oxonium cations, the same stoichiometry in a reaction with benzaldehyde resulted in formation of a hemiprotonated, hydrogen-bridged dimeric cation. Hemiprotonated acetaldehyde was obtained when a 2:1 ratio of aldehyde and SbF5 was used. Experimental and NBO analyses quantify the significant increase in electrophilicity of the oxonium cations compared to that of the parent ketones/aldehydes.

Hexakis(carbonyl)iron(II) undecafluorodiantimonate(V), [Fe(CO)6][Sb2F11]2, and -hexafluoroantimonate(V), [Fe(CO)6][SbF6]2, their syntheses, and spectroscopic and structural characterization by single crystal X-ray diffraction and normal coordinate analysis

Hexakis(carbonyl)iron(II) undecafluorodiantimonate(V), [Fe(CO)6][Sb2F11]2, is conveniently prepared by the oxidative carbonylation of Fe(CO)5 with XeF2 as external oxidizer in the conjugate Bronsted-Lewis superacid HF-SbF5. The colorless compound crystallizes from the reaction medium in high purity. The molecular structure is obtained by single-crystal X-ray diffraction. The cation is a regular octahedron, while the vertex-shared di-octahedral [Sb2F11]- anion is distorted from D4(h) symmetry by bending and rotational processes, due to significant interionic interactions, primarily of the F · · · C type. Washing of [Fe(CO)6][Sb2F11]2 with anhydrous HF results in an unusual elution of SbF5 and the quantitative conversion to hexakis(carbonyl)iron(II) hexafluoroantimonate(V) [Fe(CO)6][SbF6]2. The molecular structure of the salt shows octahedral ions with slight tetragonal distortions for the cation (elongation) and the anion (compression). Both salts are thermally stable up to 150 °C. The averaged bond distances and the vibrational wavenumbers of [Fe(CO)6]2+ are nearly identical in both compounds. The [Fe(CO)6]2+ cation, the first and so far only isolated and structurally characterized dipositive, superelectrophilic carbonyl cation formed by a 3d-metal, is further characterized by a normal coordinate analysis (NCA). The obtained force constants are compared to those of the isoelectronic molecule Cr(CO)6. Changes in π-back-bonding affect the F(CO/CO) and F(CO/MC) interaction force constants more strongly than the stretching force constants F(CO) and F(MC). All 13 fundamentals of [Fe(CO)6]2+ are detected and assigned with the help of the data obtained from the normal coordinate analysis and density functional calculations published previously. The electronic ground state 1A1(g) of the [Fe(CO)6]2+ cation is established by magnetic susceptibility measurements of polycrystalline [Fe(CO)6][SbF6]2 and [Fe(CO)6][Sb2F11]2 between 2 and 300 K. The magnetic impurity formed during synthesis is identified as Fe[SbF6]2 which has iron(II) in high spin (5T2(g)) ground state. Consistent with a diamagnetic ground state are the single line in the 57Fe Mossbauer spectrum (i.s. = -0.003(8) mm s-1 relative to α-Fe), obtained on polycrystalline samples and the single sharp line in the 13C NMR spectrum in DF solution at 178 ppm with J (57Fe- 13C) of 19.2 Hz.

Mixed Noble-Gas Compounds of Krypton(II) and Xenon(VI); [F5Xe(FKrF)AsF6] and [F5Xe(FKrF)2AsF6]

The coordination chemistry of KrF2 has been limited in contrast with that of XeF2, which exhibits a far richer coordination chemistry with main-group and transition-metal cations. In the present work, reactions of [XeF5][AsF6] with KrF2 in anhydrous HF solvent afforded [F5Xe(FKrF)AsF6] and [F5Xe(FKrF)2AsF6], the first mixed krypton/xenon compounds. X-ray crystal structures and Raman spectra show the KrF2 ligands and [AsF6]? anions are F-coordinated to the xenon atoms of the [XeF5]+ cations. Quantum-chemical calculations are consistent with essentially noncovalent ligand?xenon bonds that may be described in terms of σ-hole bonding. These complexes significantly extend the XeF2–KrF2 analogy and the limited chemistry of krypton by introducing a new class of coordination compound in which KrF2 functions as a ligand that coordinates to xenon(VI). The HF solvates, [F5Xe(FH)AsF6] and [F5Xe(FH)SbF6], are also characterized in this study and they provide rare examples of HF coordinated to xenon(VI).

METHOD FOR MANUFACTURE OF 1,1,1-TRIFLUORO-2-CHLOROETHANE (HCFC 133A) AND/OR TRFLUOROETHYLAMINE (TFEA)

-

Page/Page column 26, (2020/06/05)

A method for manufacture of 1, 1, 1-trifluoro-2-chloroethane (HCFC-133a) and/or trifluoroethylamine (TFEA), wherein at least one reaction step takes place in a microreactor that is comprising or is made of SiC-microreactor, the processes can be efficiently combined in that HCFC-133a produced by using a microreactor, may preferably advantageously serve as starting material and/or intermediate material in the manufacture of TFEA. The HCFC-133a and/or the TFEA can be easily, by a method with only low energy consumption, purified and/or isolated, and preferably the process for purifying and/or isolating does not require a distillation. Advantageously, the separation from excess hydrogen fluoride (HF) and catalyst can easily take place in an energy-saving manner by phase separation.

Crystal structures of phases observed in [H3O]+/M2+/[SbF6]?system (M?=?Mg, Cr, Mn, Fe, Co, Ni, Cu, Zn, Pd, Cd)

, p. 82 - 88 (2016/12/14)

The reactions between the MO (M?=?Be, Mg, Ca, Sr, Ti, V, Nb, Mn, Ni, Cu, Pd, Zn, Hg, Sn, Pb) and SbF5in liquid aHF were investigated. Reactions with the MO (M?=?Mg, Ni, Cu and Zn) yielded H3OM(SbF6)3compounds. Both BeO and PdO didn't show any sign of reactivity meanwhile MO (M?=?V, Nb, Ti) gave products with M in oxidation state higher than two. The rest of the MO (M?=?Ca, Sr, Mn, Hg, Sn, Pb) formed mixtures of M(SbF6)2, H3OSbF6and/or H3OSb2F11. Reactions between H3OSbF6and M(SbF6)2(M?=?Fe, Co, Ni) also gave H3OM(SbF6)3compounds, meanwhile similar attempts with H3OSbF6and M(SbF6)2(M?=?Ca, Mn, Pd, Ag, Cd, Sn) to prepare [H3O]+/M2+/[SbF6]?salts failled. However, slow crystallizations of H3OSbF6and M(SbF6)2(M?=?Mn, Pd, Cd) mixtures resulted in the single crystal growth of new (H3O)3M(SbF6)5phases which crystal structures are not isotypic. Similar procedure with H3OSbF6/Cr(SbF6)2mixture resulted in few light orange crystals of (H3O)3[CrIV(SbF6)6](Sb2F11)·HF. Its crystal structure determination showed the presence of discrete [CrIV(SbF6)6]2?units where each of Cr atoms is found in a homoleptic coordination of six SbF6groups.
