化学的特性
Boron tribromide is a colorless, fuming liquid.
-
使用
Boron Tribromide is used as a reagent in the synthesis of 8-hydroxyquinolato compounds used as electron transport materials in EL devices. It is also used in the demethylation of aryl methyl ethers by
boron tribromide.
-
主な応用
The primary use of
boron tribromide is as an initiator for the
polymerization of olefins and as a catalyst in
other organic reactions. It is also used in the
electronics industry as a source of bromine for
ion implantation in semiconductors, and for
plasma etching in semiconductor device
manufacturing.

一般的な説明
A colorless, fuming liquid with a pungent odor. Boiling point 194°F. Freezing point -51°F. Very toxic by inhalation. Corrosive to metals and tissue.
-
反応プロフィール
Boron tribromide strongly attacks wood and rubber with generation of flammable hydrogen gas. Reacts exothermically and violently with water. Mixing tungsten trioxide and Boron tribromide caused an explosion when the reaction was not cooled in an ice bath.
-
危険性
Corrosive to tissue. May explode when
heated. Upper respiratory tract irritant.
-
健康ハザード
Inhalation causes severe irritation of mucous membranes. Ingestion causes burns of mouth and stomach. Contact with eyes or skin causes severe burns.
-
火災危険
Special Hazards of Combustion Products: Toxic fumes of the chemical or hydrogen bromide may form in fires.
-
職業ばく露
Boron tribromide is highly toxic and
corrosive, it is used as a catalyst in organic synthesis, making
diborane, high purity boron, and semiconductors.
