PROCESS FOR PRODUCTION OF ALKYL TIN ALKOXIDE COMPOUND, AND PROCESS FOR PRODUCTION OF CARBONATE ESTER USING THE COMPOUND

The present invention provides a process for producing : a compound represented by XOR2; a dialkyl tin dialkoxide compound having one tin atom, two Sn-R1 bonds and two Sn-OR2 bonds; and/or a tetraalkyl dialkoxy distannoxane compound having one Sn-O-Sn bond, in which each tin atom of the tetraalkyl dialkoxy distannoxane compound has two Sn-R1 bonds and one Sn-OR2 bond, the process comprising reacting in the absence of a catalyst at least one alkyl tin compound selected from the group consisting of i) and ii) below: i) a dialkyl tin compound having one tin atom, two Sn-R1 (wherein R1 represents an alkyl group) bonds, and two Sn-OX bonds (wherein OX is a group in which HOX that is a conjugate acid of OX is a Bronsted acid having a pKa of from 0 to 6.8); and ii) a tetraalkyl distannoxane compound having one Sn-O-Sn bond, in which each tin atom of the tetraalkyl distannoxane compound has two Sn-R1 bonds and one Sn-OX bond (wherein OX is a group in which HOX that is a conjugate acid of OX is a Bronsted acid having a pKa of from 0 to 6.8); and a carbonic acid ester represented by R2OCOOR2 (wherein R2 represents a linear or branched, saturated or unsaturated hydrocarbon group, a hydrocarbon group having a saturated or unsaturated cyclic hydrocarbon substituent, or a Y-CH2- group (wherein Y represents an alkyl polyalkylene group, an aromatic group or a cyclic saturated or unsaturated alkylene ether group)), and/or an alcohol represented by R2OH (wherein R2 is the same as defined above).

PROCESS FOR PRODUCTION OF DIALKYLTIN DIALKOXIDES

An object of the present invention is to provide a process for producing a dialkyl tin compound from a composition of deactivated forms of a dialkyl tin catalyst, and to provide a process for producing the dialkyl tin catalyst from the dialkyl tin compound and using the dialkyl tin catalyst to produce a carbonic acid ester. According to the present invention, a process for producing a dialkyl tin compound is provided that subjects a composition of the deactivated forms of the dialkyl tin catalyst, formed when producing an ester compound, to an alkyl group redistribution reaction and/or dealkylation reaction.
