実験手順

A suitable reaction vessel was charged with 14.48 grams (0.362 mole) of sodium hydroxide dissolved in 80 ml water. A solution of 28.77 grams (0.131 mole) of dimethyltin dichloride and 7.92 grams (0.033 mole) of monomethyltin trichloride was added at a rate sufficient to maintain the exothermic reaction mixture at or below 75° C. Then, 75.1 grams (0.362 mole) isooctylthioglycolate was added and reacted. After separating off the aqueous phase, the oily product phase was vacuum stripped and filtered to yield 100 grams of a 75% dimethyltin bis(isooctylthioglycolate)/25% monomethyltin tris(isooctylthioglycolate) mixture.
