Patent ID: 7812188

Claim:
A method of purifying organosilicon compounds, comprising: A) providing an adsorbent; B) exposing the adsorbent to a treating compound selected from the group consisting of 3-methacryloxypropyltrimethoxysilane and tetramethylcyclotetrasiloxane; and C) allowing a composition containing at least one organosilicon compound to pass through the exposed adsorbent, wherein the organosilicon compound comprises at least one member selected from the group consisting of: i) SiR 1 R 2 R 3 R 4 , wherein each of the R 1 -R 4 is independently either H, CH 3 (CH 2 ) n , or CH 3 (CH 2 ) n O, at least one of the R 1 -R 4 is CH 3 (CH 2 ) n O, and n is independently 0 or 1, ii) SiR 1 R 2 R 3 —SiR 4 R 5 R 6 , wherein each of the R 1 -R 6 is independently either H, CH 3 (CH 2 ) n , or CH 3 (CH 2 ) n O, at least one of the R 1 -R 6 is CH 3 (CH 2 ) n O, and n is independently 0 or 1, iii) SiR 1 R 2 R 3 —O—SiR 4 R 5 R 6 , wherein each of the R 1 -R 6 is independently either H, CH 3 (CH 2 ) n , or CH 3 (CH 2 ) n O, and n is independently 0 or 1, wherein each of the R 1 -R 8 is independently either H, CH 3 (CH 2 ) n , or [OCH 3 (CH 2 ) n ] m SiH p , n=0-1, m=1-4, p=0-3, and m+p=4, and wherein each of the R 1 -R 6 is independently either H, CH 3 (CH 2 ) n , or [OCH 3 (CH 2 ) n ] m SiH p , n=0-1, m=1-4, p=0-3, and m p=4.
