용도Highly spin-polarized chromium dioxide (CrO2) thin films were deposited on 100 TiO2 substrates by chemical vapor deposition using chromyl chloride as a precursor. Chromyl chloride (Cr02C12) reacts with cyclohexane solvent at 75 OC to give a dark precipitate along with chlorocyclohexane and a small amount of cyclohexene (in 10.0 and ca. 0.3% yields based on chromium). Chromyl chloride, CrO2C12, oxidizes cyclooctane, isobutane, and toluene under mild conditions (25-60" C). The reactions give chlorinated products (chlorocyclooctane, tert- butyl chloride, and benzyl chloride) and a dark chromium-containing precipitate. Used for Organic oxidations and chlorination, chromium coordination complexes, catalyst for polymerization of olefins. Chromyl chloride in carbon tetrachloride solution reacts in the cold with cyclohexene, cyclopentene, and 1-hexene to give the various isomeric chlorohydrins as the major products.

일반 설명A dark red fuming liquid with a pungent odor. Corrosive to tissue.

Chromyl chloride is prepared by reacting chromium(III) chloride with hydrochloric acid: CrO3 + 2HCl → CrO2Cl2 + H2O Also, it may be prepared by warming potassium dichromate with potassium chloride in concentrated sulfuric acid: K2Cr2O7 + 4KCl + 3H2SO4 → 2Cr2O2Cl2 + 3K2SO4 + 3H2O.
