Chloro Silanes

SiSiB is a worldwide leading manufacturer of organosilanes for over 30 years. SiSiB chlorosilanes are a group of reactive, chlorine-containing silicon compounds. Each such compound has at least one silicon-chlorine bond. Usually chlorosilanes are intermediates used to produce siloxanes and silanes, also used as protecting agent for intermediates in pharmaceutical syntheses. Most of chlorosilanes are clear liquids that react with water to form corrosive and toxic hydrogen chloride gas and hydrochloric acid.

Chloro silanes undergo hydrolysis gives short-chain polymers and polycondensation under catalysts obtains and chain terminators produces required molecular weight of final products, such as silicone oils, silicone gums and silicone resins.

Methyl chlorosilanes have one to three methyl groups, such as Dimethylchlorosilane M2, Trimethylchlorosilane M3, Methyltrichlorosilane M1, are basic material to synthesis various silicone substances. They are directly synthesized by silicon powder and methyl chloride gas under the effect of catalyst. SiSiB, a reliable silicone manufacturer, also provides propyl chlorosilanes, vinyl chlorosilanes and phenyl chlorosilanes. Typical products include SiSiB® PC5930 (Propyltrichlorosilane), SiSiB® PC6100 (Vinyltrichlorosilane), SiSiB® PC6300 (Vinylmethyldichlorosilane), SiSiB® PC8130 (Phenyltrichlorosilane), SiSiB® PC8220 (Diphenyldichlorosilane) and SiSiB® PC8310 (Triphenylchlorosilane).

SiSiB® PC5620 (Triethychlorosilane), SiSiB® PC5710 (tert-Butyldimethylchlorosilane), SiSiB® PC8710 (tert-Butyldiphenylchlorosilane) are typical silane protective agents, which can protect or deprotect functional groups selectively. They are widely used in the syntheses of pharmaceutical intermediates.

Chlorosilane may release toxic and/or flammable gases upon reacting vigorously with bases and organic/inorganic acids. Chlorosilane even react with water/moist air/steam to give heat, toxic and corrosive hydrogen chloride, maybe also flammable hydrogen gases. To ensure the safety of transportation, packing with good tightness is necessary.
