TETRAETHYLSILANE Chemical Properties,Usage,Production

Description

Triethylsilane is a kind of tetra-alkylsilicon hydride. It can be used as the intermediates of OLED, pharmaceuticals. It can also be used as safe organosilane sources for the chemical vapor deposition of SiC films.

Chemical Properties

Clear to straw liquid

Uses

Used as the intermediates of OLED, pharmaceuticals.

Purification Methods

Fractionate it through a 3ft vacuum-jacketted column packed with 1/4" stainless steel saddles. The material is finally percolated through a 2ft column packed with alumina and maintained in an inert atmosphere. [Staveley et al.
