Abstract
The catalytic and thermal solid-phase hydrosilylation of acrylic acid was studied. It has been established that the catalytic and thermal so lid-phase hydrosilylations of acrylic acid proceeding at a high reagen t pressure, are complicated mainly by the secondary process of hydroly sis of silicon hydride groups on the silica surface. The thermal solid -phase hydrosilylation at the reagent saturated vapour pressure involv es both the C=C and C=O bonds of acrylic acid molecules.
