Specification
Trichloro(hexadecyl)silane with CAS number of 5894-60-0 is also named as Hexadecyltrichlorosilane ; N-hexadecyltrichlorosilane ; Trichlorohexadecylsilane ; Hexadecyltrichloro-silan ; Trichlorohexadecyl-silan . Reacts violently with water, steam, moist air, alcohols, acetone, light metals with generation of heat and combustible (H2) and corrosive (HCl) gases. Inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Contact with molten substance may cause severe burns to skin and eyes. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air.
