• 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
