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.
本发明的目的是提供一种从二烷基锡催化剂的失活形式组成物中生产二烷基锡化合物的方法,并提供一种从二烷基锡化合物生产二烷基锡催化剂并使用该二烷基锡催化剂生产碳酸酯的方法。根据本发明,提供了一种生产二烷基锡化合物的方法,该方法将在生产酯化合物时形成的二烷基锡催化剂的失活形式组成物经过烷基重分布反应和/或脱烷基反应。
