Dimethyldichlorosilane is a tetrahedral organosilicon compound with the formula Si(CH 3) 2 Cl 2. At room temperature it is a colorless liquid that readily reacts with water to form both linear and cyclic Si-O chains. Dimethyldichlorosilane is made on an industrial scale as the principal precursor to dimethylsilicone and polysilane compounds.
2 CH 3 Cl + Si → (CH 3) 4−n SiCl n + other products While this reaction is the standard in industrial silicone production and is nearly identical to the first direct synthesis of methyltrichlorosilane, the overall process is inefficient with respect to methyltrichlorosilane. [ 2 ]
2 ((CH 3) 3 SiCl + H 2 O → [(CH 3) 3 Si] 2 O + 2 HCl. The analogous reaction of dimethyldichlorosilane gives siloxane polymers or rings: n (CH 3) 2 SiCl 2 + n H 2 O → [(CH 3) 2 SiO] n + 2n HCl. Many compounds containing Si-Cl bonds can be converted to hydrides using lithium aluminium hydride, This kind of conversion was demonstrated for the ...
The heat of evaporation is 45.64 kJ·mol −1, the evaporation entropy 123 J·K −1 ·mol −1. [2] The vapor pressure function according to Antoine is obtained as log 10 (P/1 bar) = A − B/(T + C) (P in bar, T in K) with A = 5.44591, B = 1767.766 K and C = −44.888 K in a temperature range from 291 K to 358 K. [ 2 ] Below the melting point ...
The phosphorus atoms can be shared to form different patterns e.g. [Si 2 P 6] 10− which forms pairs, and [Si 3 P 7] 3− which contains two-dimensional double layer sheets. [1] SiP 4 ] 8− with isolated tetrahedra , and [SiP 2 ] 2− with a three dimensional network with shared tetrahedron corners. [ 2 ]
