Abstract

Esters of orthosilicic acid in which the silicon atom is bound to the glycerine radicle are prepared by heating the known simple orthosilicic esters with glycerides containing at least one free hydroxyl group in the glycerine radicle. The tetra-alkyl esters derived from methyl, ethyl, propyl, butyl, or amyl alcohols, or esters derived from cyclohexanol, methylcyclohexanol, phenol or cresol may be reacted with mono- or di-glycerides of butyric, palmitic, stearic, oleic or ricinoleic acids, or glycerides containing two different acid radicles. The temperature is preferably about 150 DEG C. Inert diluents, e.g. benzene or toluene, and pressures of 5--10 atmospheres may be employed. Primary, secondary or mixed esters are obtained depending on the molecular proportions of the reactants employed. They are recovered by distilling off the alcohols formed, preferably using reduced pressure. The esters are soluble in ether and lipins and are used in pharmacy. Examples describe the reaction of mono- or di-butyrin, stearin, or olein with silicic acid tetraethyl or tetraphenyl ester at 150 or 140 DEG C. under pressure. An atmosphere of carbon dioxide is used when employing oleins.
