反応手順
A carbinol functional siloxane having Structure VIII was prepared by hydrosilylation. Specifically, 1.2 parts by weight of 1-allyloxy-2-propanol in the presence of a catalytic amount of chloroplatinic acid (10 ppm platinum as a solution of 7.5% by weight in isopropanol) and 0.004 parts by weight of magnesium silicate was warmed to 80° C. under inert atmosphere. One part by weight 1,1,1,3,5,5,5-heptamethyltrisiloxane was added through an addition funnel over 5 hours. The mixture was treated with 0.02 parts by weight of a 35% solution of aqueous hydrogen peroxide and stirred for two hours at 80° C. Filtration yields [3-[1,3,3,3-tetramethyl-1-[(trimethylsilyl)oxy]disiloxanyl]propoxy]-propanol (CAS# [77623-99-5]) as a water white liquid.
