Preparation of branched siloxane

By reacting a branched siloxane compound of formula (2) containing compounds of formula (1) as an impurity with a disiloxane compound of formula (3) in the presence of an acid compound, there is prepared a branched siloxane of formula (2) containing a reduced level of compounds of formula (1).R1?nSi(OSiR2?3)3-n(OR3)R1?nSi(OSiR2?3)4-nR2?3SiOSiR2?3 R1 is a monovalent hydrocarbon group, R2 and R3 are H or monovalent hydrocarbon groups, and n is 0 or 1.

Preparation of Alkyl-substituted Partial Trimethylsilyl Silicates from Olivine

The direct trimethylsilylation reaction of olivine has yielded partial trimethylsilyl derivatives of ortho- and di-silicates whose unsilylated silanol groups have been esterified with the alcohol used as the organic solvent in the trimethylsilylating reagent.Gas chromatographic-mass spectroscopic measurements indicate the presence of the tri-, di-, and mono-alkyl-substituted trimethylsilyl derivatives of monosilicic acid in addition to the fully silylated monomeric derivative .Dimeric derivatives have also been detected which contain both the completely trimethylsilylated derivative and alcohol-esterified derivatives .The ratio of the esterified products varies with the volume of alcohol or water in the silylating reagent as well as the reaction time.
