Siliconorganic compounds

The synthesised siliconorganic compounds were investigated using by functional and elementary analysis, molecular mass determination, IR and NMR spectra data [7]. Yields and some physical-chemical properties of synthesised organocyclosiloxanes are presented in Table 6.1. 

The atom of siflcon connected with unsaturated aliphatic group, should facilitate its oxidation by peracids. In the same conditions vinyl derivative of silicon reacts with peracetic acid [4], perbenzoic acid [12] much more slowly than allyl-derivative. In siliconorganic compounds where double... 

The oxidative epoxidation reactions of unsaturated siliconorganic compounds by perbenzoic acid in chloroform and tetrachloromethane proceeds significantly r idly than another solvents, though by using less active solvents (ether, tetrahydrofurane) is possible exception of secondary reactions. In addition it was shown [18] that oxidative epoxidation of vinyl containing sili-conoiganic compounds by tertiary-butyl aleohol in the presence of Mo(CO)g in benzene solution at 40°C epoxy deievatives is abot 60-70%. 

Possible fields of application the properties of compositions and polymers on a basis of dian-epoxy resin ED-20 and epoxy-novolac resin UP-643 which have been diluted by epoxy group containing siliconorganic compounds have been considered.
