The results showed high class PbSt2 could be synthesized by this new saponifying process.Compared with metathetical process,the reaction time shortened,liquid-solid ratio and moisture content of filter cake decreased.Powder product could be prepared by one-step process,and particle product by two-step process.For the optimum processing conditions,the reaction temperature and time for one-step process were 65℃ and 10min,the amount of alkali added in the first step was 50%;reaction temperture and time were 65℃ and 10min for the two-step process.

结果表明，用皂化法工艺可得到优等品PbSt2，较复分解工艺，反应时间缩短、液-固比降低、滤饼湿含量比减小，一步式工艺得到粉状产品，二步式工艺得到颗粒状产品；最佳工艺条件为：一步式工艺反应温度65℃，反应时间10min；二步式工艺第一步的加碱量比50%，反应温度65℃，反应时间10min。

MPH plastic magnetic pump complies with JB/T7742-1995Standard for Small Magnetic Transmission Centrifugal Pump. Its flow-through parts adopt PPS with corrosion resistance to most acid, alkali and salt (except oxidable acid like strong sul-furic acid, nitric acid and aqua regia). Its performance is close to the chemical performance of F4, which can resist to most organic solvents under 100℃, especially to the mixture of gas and carbinol. Thus it is an ideal pump for acid and alkali industries.
