565-00-4 Usage

Chemical Properties

Camphene is a colorless to white crystalline solid, Camphor, or turpentine odor. It may be shipped as a liquid. Freezing/Melting point 5 50C.

Potential Exposure

Camphene is used to manufacture synthetic camphor; for making moth-proofing and in the cosmetics, perfume, and food flavoring industries.

Shipping

UN1325 Flammable solids, organic, n.o.s., Hazard Class: 4.1; Labels: 4.1-Flammable solid. UN2319 Terpene hydrocarbons, n.o.s., Hazard Class: 3; Labels: 3- Flammable liquid

Purification Methods

Crystallise it twice from EtOH, then repeatedly melted and frozen at 30mm pressure. [Williams & Smyth J Am Chem Soc 84 1808 1962.] Alternatively it is dissolved in Et2O, dried over CaCl2 and Na, filtered, evaporated and the residue is sublimed in a vacuum [NMR: Hana & Koch Chem Ber 111 2527 1978].

Incompatibilities

Forms explosive mixture with air. Emulsions in xylene may violently decompose on contact with iron or aluminum above 70C. 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. Contact with reducing agents may cause exothermic reaction, releasing flammable hydrogen gas

Waste Disposal

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.

Check Digit Verification of cas no

The CAS Registry Mumber 565-00-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 5 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 565-00:
(5*5)+(4*6)+(3*5)+(2*0)+(1*0)=64
64 % 10 = 4
So 565-00-4 is a valid CAS Registry Number.

ZrO2-SiO2 mixed oxides xerogel and aerogel as solid acid catalysts for solvent free isomerization of α-pinene and dehydration of 4-methyl-2-pentanol

Sidhpuria, Kalpesh B.,Tyagi, Beena,Jasra, Raksh V.

experimental part, p. 1164 - 1170 (2012/06/30)

Sulfated and non-sulfated ZrO2-SiO2 mixed oxide xerogel and aerogel samples having varied Zr/Si molar ratio were evaluated as solid acid catalysts for the isomerization of α-pinene and dehydration of 4-methyl-2-pentanol. Sulfation resulted into enhancement in the catalytic activity of both xerogel and aerogel samples towards the studied reactions. For example, sulfated catalysts showed 86-98% conversion of α-pinene and 8-35% conversion of 4-methyl-2-pentanol. The selectivity data for camphene and limonene indicated the requirement of moderate acidity. The correlation with cyclohexanol dehydration showed that isomerization of α-pinene is a Bronsted acid catalyzed reaction. The relationship of 4-methyl-2-pentanol conversion with acid site density and sulfur per unit area was found to be linear.

Liquid Crystalline Catalysis, 3, Monomolecular Rearrangements of Terpene Derivatives in Liquid Crystalline Solvents

Melone, S.,Mosini, V.,Nicoletti, R.,Samori, B.,Torquati, G.

, p. 399 - 410 (2007/10/02)

The ability of limonene and linalool to rearrange in mesomorphic media is apparently determined by the constraints exerted by the solvent structure on the translational diffusions of the reactant solute molecules.Selective conversions seem to be promoted by the different media.Alkylcyclohexyl- and alkylbicyclohexyl-carboxylic acids and their mixtures with toluic acid have been used as solvents.The B structure of their smectic phases has been demonstrated by X-ray diffraction studies.

Effect of Sulfate Ions on Activity of TiO2, Fe2O3 and ZrO2 for the 2-Pinene Isomerization Reaction

Ohnishi, Ryuichiro,Morikawa, Toshiyuki,Hiraga, Yoshizumi,Tanabe, Kozo

, p. 205 - 210 (2007/10/02)

Treatment of titanium oxide, Fe2O3 and ZrO2 with (NH4)2SO4 brought high catalytic activity for isomerization of 2-pinene.The selectivities of the catalysts for formation of camphene and 1,7,7-trimethyltricyclo2.6>heptane(tricyclene) were high (60-70 percent).The effect of sulfate ions has been interpreted in terms of surface acid strenght.Key words: Oxides / Sulphate ion / Isomerization / 2-Pinene
