摘要
利用椰壳制备的固体炭磺酸催化环氧苯乙烷的醇开环反应。考察了椰壳炭磺酸催化剂用量,溶剂对产率的影响。比较了椰壳炭磺酸与磺酸树脂、对甲苯磺酸和硫酸氢钠等传统磺酸型催化剂在该反应中的催化性能。结果表明,椰壳炭磺酸是一种绿色高效的固体酸催化剂。
The alcoholysis of styrene oxide was catalyzed by coconut shell char sulfonic acid, a novel solid sulfonic acid catalyst, was prepared from coconut shell,The effects of catalyst amoumt and solvent on the yield were investigated. The catalytic performance of coconut shell char sulfonic acid was compared with sulfonic resin,p-toluene sulfonic acid and soldium hydrogen sulfate. It was indicated that coconut shell char sulfonic acid is a green and efficient catalyst.
