  • Published:1994-12-25

本文研究 了在非极性溶剂二氯甲烷中卤代苯和卤代萘用SO~3进行的磺化反应. 卤代苯最初开始磺化反应的产物是4-磺酸, 2-卤代萘的产物是8-磺酸. 当用过量的SO~3长时间反应时, 磺化反应得到三取代产物.

关键词: 磺化, 三氧化硫, 卤代苯, 卤代萘

In dichloromethane the sulfonation of halobenzenes and halonaphalenes with SO~3 was studied. The products of initial sulfonation for halobenzenes were 4-sulfonic acids, and the products for 2-halonaphathalenes were 8-sulfonic acids. Under large excess of SO~3 and longer reaction time, the trisubstitute products for sulfonation reaction were obtained.

Key words: SULFUR TRIOXIDE, HALOGENO-BENZENE, SULFONATION, NAPHTHALENE HALIDE
