摘　　要：在采用烷基苯SO3磺化工艺制造烷基苯磺酸过程中,许多装置会遇到含量、色泽不稳定的问题。通过对某合成洗涤剂厂烷基苯SO3磺化设备、工艺等因素的研究分析,对生产工艺进行了系统改进,烷基苯磺酸含量稳定在96%以上,色泽稳定在30klett以下。After observing the technics of 1t/h wash factory and studying the factors which effect the quality of alkylbenzene sulfonic acid for a trolling of the mole ratio of SO_3/LAB. In that case, A rebuilding project ware designed mostly included the increasing cool area of air designed, the reconstruction of water column, the controlling of the stored temperature and the controlling of the mole ratio of SO_3/LAB etc.

关 键 词：工艺改进 SO3磺化 烷基苯磺酸
