Disiloxane is an inorganic compound, a silicon analogue of dimethyl ether with the formula (SiH ₃ ) ₂ O, a colorless gas, stable at room temperature, slowly reacting with water.

Content

Getting

Bromosilane reaction with water:

{\mathsf {2SiH_{3}Br+H_{2}O\ {\xrightarrow {0^{o}C}}\ (SiH_{3})_{2}O+2HBr}}

{\ displaystyle {\ mathsf {2SiH_ {3} Br + H_ {2} O \ {\ xrightarrow {0 ^ {o} C}} \ (SiH_ {3}) _ {2} O + 2HBr}}}

Physical Properties

Disiloxane forms a colorless gas, is stable at room temperature, and slowly reacts with water.

Chemical Properties

Slowly reacts with water (alkali dramatically accelerate the reaction):

{\mathsf {(SiH_{3})_{2}O+3H_{2}O\ {\xrightarrow {}}\ 2SiO_{2}+6H_{2}\uparrow }}

{\ displaystyle {\ mathsf {(SiH_ {3}) _ {2} O + 3H_ {2} O \ {\ xrightarrow {}} \ 2SiO_ {2} + 6H_ {2} \ uparrow}}}
