tert-Butyl chromate solution in carbon tetrachloride Chemical Properties,Uses,Production
Chemical Properties
tert-Butyl chromate is a highly flammable, clear, colorless, hygroscopic, corrosive, flammable liquid or red crystals from petroleum ether. Solution in carbon tetrachloride is highly flammable.
Uses
In specialty reactions as a source of Cr; manufacture of catalysts; polymerization of olefins; curing agent for urethane resins
General Description
Liquid.
Air & Water Reactions
Highly flammable. Is hydrolyzed by water.
Reactivity Profile
Unstable except in solution.
Hazard
Toxic by skin absorption. A very powerful oxidizer and dangerous fire hazard. Skin and lower respiratory tract irritant.
Health Hazard
tert-Butyl chromate is expected to cause irritation of the eyes, nose, and skin. Skin contact with tert-butyl chromate caused necrosis of the skin and death of rats.1 In another report exposed rats had an increase in respiratory rate and signs of mild narcosis.
Fire Hazard
Literature sources indicate that tert-Butyl chromate solution in carbon tetrachloride is flammable.
Safety Profile
A very flammable mixture. When heated to decomposition it emits acrid and irritating fumes. See CHROMIUM COMPOUNDS and ESTERS.
Potential Exposure
Butyl chromate is used in specialty reactions as an organic source of chromium; in making catalysts; and as a curing agent for urethane foams
Carcinogenicity
tert-Butyl chromate is considered to be an inferred carcinogen because it is a hexavalent chromium compound.
Shipping
UN3082 Environmentally hazardous substances, liquid, n.o.s., Hazard class: 9; Labels: 9—Miscellaneous hazardous material, Technical Name Required
Incompatibilities
tert-Butyl chromate is a strong oxidizer; reacts violently with reducing agents (such as lithium, sodium, aluminum and their hydrides and hydrazine); combustible materials. Water solutions of tert-butyl chromate react violently with strong bases. Incompatible with strong acids (i.e., hydrochloric, sulfuric and nitric); alcohols, and easily oxidized materials, such as paper, wood, sulfur, aluminum and plastics
