As orthosilicic acid, a basic element of glass, silicones and zeolites, is unstable in water and can not be isolated, it was synthesized in an amide solvent using a palladium/carbon catalyst for hydrocracking from a silicon compounds having 4 benzyloxy groups, obtaining orthosilicic acid at 96% yield. Orthosilicic acid was very stably in the absence of water, could be crystallized and subjected to x-ray structure analysis and neutron diffraction. The results are expected to help synthesize silicones of better controlled structure, leading to the manufacture of highly functional and high performance silicon materials.
