三氧化硫法合成对氯苯磺酸

Study on Synthesis of Parachlorophenylsulfonic Acid by Sulfur Trioxide Method

比较了氯苯磺化制备对氯苯磺酸的磺化剂，研究了磺化能力强的三氯化硫磺化工艺，探讨了各种因素对磺化转化率的关系，确定了适宜的合成工艺。

In this papers, the appropriate synthetic technology of parachlorophenglsulfonic acid was established by comparing different sulfonating agents. The sulfonated technology of sulfur trioxide and the effects has also been studied.
