This invention relates to novel organotin compounds containing at least one sulfur atom that is bonded exclusively to tin or to tin and hydrogen. The compounds are derivatives of mercaptoalkanols, which are present as the free alcohols, as esters of polycarboxylic acids, esters of acids containing specified non-metallic elements or as alkoxides of specified metallic elements. The compounds are effective catalysts for a variety of reactions and impart heat stability to halogen-containing resins.
这项发明涉及包含至少一个硫原子的新型有机锡化合物,该硫原子仅与锡或锡和氢键合。这些化合物是巯基烷醇的衍生物,以游离醇的形式存在,作为多羧酸酯、含有特定非金属元素的酸酯或特定金属元素的烷氧基的形式存在。这些化合物对各种反应具有有效的催化作用,并赋予含卤树脂热稳定性。
