13826-83-0 Usage

Chemical Properties

white crystalline powder

Uses

Ammonium fluoroborate is used as an analytical reagent. It is also applied in the textile printing and dyeing industry and used as a catalyst for resin finishing. It is mainly used for the high temperature fluxing action required by the metals industry; catalyst; in flame retardants and acts as a solid lubricant in cutting-oil emulsions for aluminum rolling and forming.

General Description

Odorless white crystals. Sinks and mixes with water.

Air & Water Reactions

Sublimes above 238°C. to form toxic fumes [AAR 1991]. Water soluble.

Reactivity Profile

Acidic inorganic salts are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

Health Hazard

INHALATION: May cause irritation of respiratory passages, nose bleeds, and nausea. EYES: May irritate.

Fire Hazard

Behavior in Fire: Sublimes above 238°C yielding toxic fumes.

Safety Profile

A poison and strong irritant. See also FLUORIDES and BORON COMPOUNDS. When heated to decomposition it emits very toxic fumes of F-, NO,, and NH3.

Purification Methods

Crystallise it from conductivity water (1mL/g) between 100o and 0o. 450 Purification of Inorganic Compounds

Check Digit Verification of cas no

The CAS Registry Mumber 13826-83-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,8,2 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 13826-83:
(7*1)+(6*3)+(5*8)+(4*2)+(3*6)+(2*8)+(1*3)=110
110 % 10 = 0
So 13826-83-0 is a valid CAS Registry Number.

Production and decomposition of (NH4)[BF4] and H3N-BF3

Gbbels, Dirk,Meyer, Gerd

, p. 1799 - 1805 (2002)

(NH4)[BF4] is produced as single crystals during the reaction of elemental boron and NH4HF2 (B:NH4HF2 = 1:2) and NH4F (B:NH4F = 1:4), respectively, in sealed copper ampoules at 300°C. The crystal structure (baryte type, orthorhombic, Pnma, Z = 4) was redetermined at ambient temperature (a = 909.73(18), b = 569.77(10), c = 729.47(11) pm, Rall = 0.0361) and at 140 K (a = 887.3(2), b = 574.59(12), c = 717.10(12)pm, Rall = 0.0321). Isolated (NH4)+ and [BF4]- tetrahedra are the important building units. The thermal behaviour of (NH4)[BF4] was investigated under inert (Ar, N2) and reactive conditions (NH3) with the aid of DTA/TG and DSC measurements and with in-situ X-ray powder diffraction as well. Finally, (NH4)[BF4] is decomposed yielding NH3 and BF3, BN is not produced under the current conditions. Colourless single crystals of H3N-BF3 were prepared directly from the components NH3 and BF3. The crystal structure was determined anew at 293 and 170 K (orthorhombic, Pbca, Z = 8, a = 815.12(10), b = 805.91(14), c = 929.03(12) pm, Rall = 0.0367; a = 807.26(13), b = 800.48(10), c = 924.31(11)pm, Rall = 0.0292, T = 170 K). The crystal structure contains isolated molecules H3N-BF3 in staggered conformation with a B-N distance of 158 pm. The thermal behaviour of H3N-BF3 was studied likewise.

Interaction of datolite concentrate with ammonium hydrodifluoride

Krysenko,Medkov,Epov

The interaction of datolite concentrate with ammonium hydrodifluoride were studied. Under heating, ammonium hydrodifluoride fluorinates datolite to form complex fluoroammonium salts of boron, silicon, and impurity metals. The activation energy and rate constants were calculated for the reaction of datolite concentrate with ammonium hydrodifluoride in the range 100-150°C. The composition of the vola-tiles formed upon the heating of the fluorinated concentrate was studied, the temperature parameters of the evolution of boron and silicon to the gas phase were determined, and a process for separating these elements was proposed.

The reactions of arenediazonium tetrafluoroborates with N,N-methylenediacrylamide in H2O-DMF (1:3) and H2O-DMSO (1:4) in the presence of thiocyanate anions involve thiocyanatoarylation by one or two multiple bonds to give [(3-aryl-2-
