Silicon derivatives of fragrant, flavouring and medicinal substances

Proposed is a method for preparing compounds of the general formula [RC(O)O]aSi(OR')4-a-bR''b, where RC(O)O is an acid radical of one or several saturated or unsaturated carboxylic acids with the number of carbon atoms from 2 to 18, a is from 0 to 3, R'' is an aliphatic grou...

More Information
Summary:Proposed is a method for preparing compounds of the general formula [RC(O)O]aSi(OR')4-a-bR''b, where RC(O)O is an acid radical of one or several saturated or unsaturated carboxylic acids with the number of carbon atoms from 2 to 18, a is from 0 to 3, R'' is an aliphatic group with the number of carbon atoms from 1 to 6, b is from 0 to 3, R'O are organoxy groups of one, two, three, or four hydroxyl-containing aromatic or medicinal substances. Owing to gradual and long hydrolysis of the alkoxy groups, the proposed compounds liberate fragrance or medicating factor, or both simultaneously, for long periods of time.
