A process for the fractional production of mono-, di- or triorganotin oxides which comprises subjecting an organotin halide to hydrolysis, separating the hydrolysis reaction mixture into three layers, and thereby obtaining the desired organotin oxide-containing layer as a triorganotin oxide--containing layer substantially free of mono- and/or diorganotin oxide, a monoorganotin oxide-containing aqueous layer, or a diorganotin oxide-containing layer substantially free of mono- and/or triorganotin oxide, and then recovering the tri-, mono- or diorganotin oxides from the desired organotin oxide-containing layers.

Organotin compounds with low tin content suitable as stabilizers for halogen containing resins e.g. polyvinyl chloride are of formula EQU1 where R1 and R2 are C1-20 alkyl, cycloalkyl or phenyl groups, Q1 represents a radical selected from the group consisting of EQU2 Q2 is a hydrogen atom, an alkyl group containing between 1 and 6 carbon atoms or the group --CH2 Z3. Z1, z2, and Z3 are individually selected from the group of groups consisting of EQU3 and EQU4 R3 is an alkyl group containing between 1 and 20 carbon atoms, a substituted or unsubstituted phenyl group or a substituted or unsubstituted alkylphenyl group. R4 is an alkyl grup containing between 1 and 20 carbon atoms, a substituted phenylakly or unsubstituted phenylalkyl group wherein the alkyl portion of the radical contains between 1 and 6 carbon atoms. R5 is an alkyl group containing between 1 and 20 carbon atoms, a substituted phenyl, unsubstituted phenyl, substituted alkylphenyl or unsubstituted alkylphenyl group. R6 represents a single bond, an alkylene group containing between 1 and 20 carbon atoms, an alkenylene group containing between 2 and 20 carbon atoms, a substituted phenylene or an unsubstituted phenylene group. R7 represents a single bond, an alkylene group containing between 1 and 20 carbon atoms, an alkenylene group containing between 2 and 20 carbon atoms, a substituted phenylene group or an unsubstituted phenylene group. R8 represents an alkylene group containing between 1 and 20 carbon atoms, said alkylene group being either unsubstituted or containing at least one phenyl group as a substituent, an alkenylene group containing between 2 and 20 carbon atoms or a cycloalkylene group containing between 5 and 6 carbon atoms. R9 represents an alkylene group containing between 1 and 20 carbon atoms. n is an integer between 1 and 6 inclusive. Y is of the formula EQU5 --SR4, EQU6 or Y and the aforementioned group EQU7 together constitute a divalent group radical of the formula EQU8 wherein both free valences of said divalent group are bonded to the same tin atom.
