| titleOfInvention | Procedure for the production of dialkyl tin dialkoxides |
| abstract | Process for producing a dialkyl tin compound, comprising: subjecting a composition in a deactivated form of a dialkyl tin catalyst, which is formed when an ester compound is produced using the dialkyl tin catalyst, to a group redistribution reaction alkyl and / or a dealkylation reaction; wherein the deactivated form of the dialkyl tin catalyst is a heat-deactivated form of the dialkyl tin catalyst that is derived from the dialkyl tin catalyst in which the number of alkyl groups attached to a single tin atom differs from the number of alkyl groups attached to a single tin atom of the dialkyl tin catalyst; wherein the dialkyl tin catalyst is at least one type of compound selected from the group comprising a dialkyl tin compound represented by the formula (1) and a tetraalkyl diestannoxane compound represented by the formula (2): * * Formula ** (in which each of R1 and R2 independently represents a linear or branched alkyl group having 1 to 12 carbon atoms, each of X1 and X2 represents, independently, at least , a type of substituent selected from the group comprising an alkoxy group, an acyloxy group and a halogen atom, a and b independently represent an integer from 0 to 2 and + b> = 2, and c and d represent, in a manner independent, an integer from 0 to 2 and c + d> = 2); ** Formula ** (in which each of R3, R4, R5 and R6 independently represents a linear or branched alkyl group having from 1 to 12 carbon atoms, each of X3 and X4 represents, of m At least one type of substituent selected from the group comprising an alkoxy group, an acyloxy group and a halogen atom, and f, g and h independently represent an integer from 0 to 2, e + f> = 2 yg + h> = 2) and, preferably, in which in formulas (1) and (2), the number of carbon atoms constituting X1, X2, X3 and X4 is a selected number from an integer from 0 to 12, in which the ester compound is at least one type of compound selected from the group comprising carbonic acid ester, carbamic acid ester and isocyanate; in which: (i) in a case in which at least one substituent between groups bonded to tin atoms of the deactivated form of the dialkyl tin catalyst other than the alkyl groups that come from the dialkyl tin catalyst is a group acyloxy or a halogen atom, the redistribution reaction of alkyl groups is a redistribution reaction of alkyl groups, in which an organic tin compound having an Sn-Y bond (in which Y represents Y, in which the pKa of a conjugated acid of Y in the form of HY, in which a hydrogen atom has been added to Y, is from 0 to 6.8, wherein HY is selected from hydrogen halide, hydrogen halide, sulfuric acid, nitric acid, phosphoric acid, carbonic acid, carboxylic acid, sulfonic acid, sulfinic acid and phenol) is heat treated; or (ii) in a case where at least one substituent between groups bonded to tin atoms in the deactivated form of the dialkyl tin catalyst other than the alkyl groups that come from the dialkyl tin catalyst is an alkoxy group, the redistribution reaction of alkyl groups comprises the steps of: (A) obtaining an organic tin compound having an Sn-Y bond by replacing all or a part of the ligands in the deactivated form (excluding a corresponding alkyl group of the dialkyl tin and tin-linked catalyst) by a substituent Y; and (B) thermally treating the organic compound having an Sn-Y bond and obtained in step (A) (in which Y represents Y, in which the pKa of a conjugated acid of Y in the form of HY, in the that a hydrogen atom has been added to Y, is from 0 to 6.8, in which HY is selected from hydrogen halide, hydrogen halide, sulfuric acid, nitric acid, phosphoric acid, carbonic acid, carboxylic acid, sulfonic acid , sulfinic acid and phenol); or (iii) the dealkylation reaction comprises forming an Sn-Y bond by removing an alkyl group from the deactivated form of the dialkyl tin catalyst (in which Y represents Y, in which the pKa of a conjugated acid of Y in the form of HY, in which a hydrogen atom has been added to Y, it is from 0 to 6.8, in which HY is selected from hydrogen halide, hydrogen halide, sulfuric acid, nitric acid, phosphoric acid, acid carbonic, carboxylic acid, sulfonic acid, sulfinic acid and phenol), and in which the dialkyl tin compound has two alkyl groups that come from the dialkyl tin catalyst and is attached to a single tin atom, having at least simultaneously a Sn-Y bond (in which Y represents Y, in which the pKa of a conjugated acid of Y in the form of HY, in which a hydrogen atom has been added to Y, is from 0 to 6.8, wherein HY is selected from hydrogen halide, halogenh acid ferric acid, sulfuric acid, nitric acid, phosphoric acid, carbonic acid, carboxylic acid, sulfonic acid, sulfinic acid and phenol). |
