Polymer-Supported Stannic Tetrachloride Complex Catalysts (Ⅱ)——Copolymer (Styrene-Methyl Methacrylate)-Stannic Tetrachloride Complex

Abstract

Abstract: Across-linked polymer carrier beads, styrene-methyl methacrylate(19%)-divinylbenzene (2%) copoiymer, were synthesized and combined with stannic chloride in chloroform to form a stable complex containing 20.5% Cl (equivalent to 1.44 mmol SnCl₄/g of complex beads).The complex showed a good catalytic activity for many organic reactions such as esterif ication, ketal formation, and etherification.The catalyst can be used for six times at least without losing its catalytic activity.

Key words: Polymer-supported catalyst, Stannic tetrachloride, Complex
