Trimethylsilanol (TMS) is an organosilicon compound with the formula (CH3)3SiOH. The Si centre bears three methyl groups and one hydroxyl group. It is a colourless volatile liquid. See more TMS is a contaminant in the atmospheres of spacecraft, where it arises from the degradation of silicone-based materials. Specifically, it is the volatile product from the hydrolysis of polydimethylsiloxane, which are generally … See more In terms of its structure, the molecule is tetrahedral. The compound forms monoclinic crystals. See more The heat of evaporation is 45.64 kJ·mol , the evaporation entropy 123 J·K ·mol . The vapor pressure function according to Antoine is obtained as log10(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 … See more Trimethylsilanol is accessible by weakly basic hydrolysis of chlorotrimethylsilane, since the dimerization can thus be avoided. Trimethylsilanol can also be obtained by the basic See more Trimethylsilanol is a weak acid with a pKa value of 11. The acidity is comparable to that of orthosilicic acid, but much higher than the one of alcohols like tert-butanol (pKa 19 ). Deprotonation with sodium hydroxide gives sodium trimethylsiloxide. TMS reacts with the See more Like other silanols, trimethylsilanol exhibits antimicrobial properties. See more Webtrimethylsilanol. Trimethylsilanol required a longer time (30 min) and a higher concentration of 2.46% g/g to achieve a similar 8 log reduction. The partition coefficient of triethylsilanol is 2.62, while that of trimethylsilanol is 1.14.
