Tributyl (chlorine) silane is a chemical compound from the group of organosilicon compounds . It is a clear, light yellow liquid with a boiling point of 250–252 ° C.

Extraction and presentation

Tributyl (chloro) silane can be produced by reacting tributylsilane with chlorine or hydrogen chloride in the presence of aluminum trichloride as a catalyst :

${\displaystyle \mathrm {HSi(CH_{2}CH_{2}CH_{2}CH_{3})_{3}+\ Cl_{2}\ {\xrightarrow {-80\,{}^{\circ }C}}\ ClSi(CH_{2}CH_{2}CH_{2}CH_{3})_{3}+\ HCl} }$

${\displaystyle \mathrm {HSi(CH_{2}CH_{2}CH_{2}CH_{3})_{3}+\ HCl\ {\xrightarrow {Al_{2}Cl_{6}}}\ ClSi(CH_{2}CH_{2}CH_{2}CH_{3})_{3}+\ H_{2}} }$
