| Rebuilding Art for the Sulfonation of Alkylbenzene |
| LUO Tao （Hunan Resun Industry Co. Ltd.; Changsha 410083; China） |
| Abstract：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. |
| Key words：rebuilding art; controlling of the mole ratio of SO_3/LAB; heat exchange system; sulfonation of sulfur trioxide; alkylbenzene sulfonic acid |
