一种新型有机锡类PVC热稳定剂的合成研究

The Synthesis of a Novel Organotin Thermal Stabilizer for PVC

利用异辛酸巯基乙酯和二丁基二氯化锡反应,合成了一种新的有机锡化合物二丁基锡双(异辛酸巯基乙酯)。探讨了溶剂种类、不同的HCl吸收剂、反应时间等操作参数对产率的影响,并通过正交实验确定了最佳的合成工艺条件,通过红外光谱和液相色谱-质谱联用仪对合成产物进行了结构表征,证明了实验产物为目标产物。

A novel organotin compound dibutyltin bis（mercaptoethyl isooctoate） was synthesized by the reaction of dibutyltin dichloride with mercaptoethyl isooctoate in 1 ： 1 molar ratio. Influences of operation parameters such as the kind of solution, HC1 absorbent and reaction time on yield were discussed, then the optimum technological conditions were determined by orthogonal experiments. The structure of product was characterized by IR and mass spectrum, and it was proved to be the target product.
