삼차-부틸 크롬산 C화학적 특성, 용도, 생산
화학적 성질
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.
용도
In specialty reactions as a source of Cr;
manufacture of catalysts; polymerization of
olefins; curing agent for urethane resins
일반 설명
Liquid.
공기와 물의 반응
Highly flammable. Is hydrolyzed by water.
반응 프로필
Unstable except in solution.
위험도
Toxic by skin absorption. A very powerful
oxidizer and dangerous fire hazard. Skin and lower
respiratory tract irritant.
건강위험
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.
화재위험
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.
잠재적 노출
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.

비 호환성
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
