物理形态与操作说明

  • Trimethoxysilane appears as a colorless liquid. Slightly soluble in water and denser than water. Hence floats on water. Very toxic by ingestion, inhalation or skin absorption. May also be corrosive to skin and eyes.
  • Liquid
  • A colorless liquid; [CAMEO]
  • Hydrolyzes rapidly in water
  • When heated to decomp, it emits acrid smoke and irritating fumes.
  • The silanes decomp at elevated temp to liberate hydrogen and deposit a high purity silicon, which leads to some of the principal uses of silanes. /Silanes/
