クロム酸ジ-tert-ブチル 化学特性,用途語,生産方法
化学的特性
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.
使用
In specialty reactions as a source of Cr;
manufacture of catalysts; polymerization of
olefins; curing agent for urethane resins
一般的な説明
Liquid.
空気と水の反応
Highly flammable. Is hydrolyzed by water.
反応プロフィール
Unstable except in solution.
危険性
Toxic by skin absorption. A very powerful
oxidizer and dangerous fire hazard. Skin and lower
respiratory tract irritant.
健康ハザード
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.
火災危険
Literature sources indicate that tert-Butyl chromate solution in carbon tetrachloride is flammable.
安全性プロファイル
A very flammable
mixture. When heated to decomposition it
emits acrid and irritating fumes. See
CHROMIUM COMPOUNDS and
ESTERS.
職業ばく露
Butyl chromate is used in specialty reactions as an organic source of chromium; in
making catalysts; and as a curing agent for urethane
foams
発がん性
tert-Butyl chromate is considered to be an
inferred carcinogen because it is a hexavalent
chromium compound.
輸送方法
UN3082 Environmentally hazardous substances,
liquid, n.o.s., Hazard class: 9; Labels: 9—Miscellaneous
hazardous material, Technical Name Required
不和合性
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
