     It is a new attempt to use the activite sulfur for the deep purification of removing copper and it cowld had a very good useful prospect. The experiment mainly researched the condition of removing copper, such as, acidity, temperature and amount of activite sulfur. The results showed that the residue copper was less than 2ppm and the slag ratio(Cu:Ni) was 100:1.

The deep purification of Nickel solution was widely studied in the world. It is a new attempt to use the activite sulfur for the deep purification of removing copper and it cowld had a very good useful prospect. The experiment mainly researched the condition of removing copper, such as, acidity, temperature and amount of activite sulfur. The results showed that the residue copper was less than 2ppm and the slag ratio(Cu:Ni) was 100:1.

In paper, Sodium Deodecyl Sulfation (SDS) is synthesized by sulfur trioxide which is obtained from oleum. The best mode of production and optimalizing control condition is obtained by determining and analyzing SDS's control index, and have a discussion on the influence factor.

研究利用从发烟硫酸中气提出的三氧化硫制备十二烷基硫酸钠,通过对其控制指标的测定与分析,选出生产十二烷基硫酸钠所需的最佳生产方式和最佳控制条件,并对其影响因素进行了讨论.

The results of semiempirical AM1 calculation of quantum chemistry indicate that in the course of TPP sulfonating, the difficulty of sulfonation increases with the increase of sulfonation reaction. An improved process for synthesis of TPPTS was suggested by introducing fresh SO 3 gas into the reactor. The tributylphosphate was employed as an extractant. With a SO 3/TPP molar ratio 12, temperature 20~24 ℃ and reaction time 66~69 h, the yield of TPPTS reaches 97.6%. TPPTS was employed as the ligand of rhodium/phosphine...

The results of semiempirical AM1 calculation of quantum chemistry indicate that in the course of TPP sulfonating, the difficulty of sulfonation increases with the increase of sulfonation reaction. An improved process for synthesis of TPPTS was suggested by introducing fresh SO 3 gas into the reactor. The tributylphosphate was employed as an extractant. With a SO 3/TPP molar ratio 12, temperature 20~24 ℃ and reaction time 66~69 h, the yield of TPPTS reaches 97.6%. TPPTS was employed as the ligand of rhodium/phosphine catalysts, which were applied to the biphase and supported aqueous phase (SAP) hydroformylation reactions. The result shows that the n/i ratio can be increased significantly, and the lose of Rh can be controlled effectively.
