After esterification, the ethyl-2-chloro-3-phenylpropionate reacts with diethyl malonate under the catalysis of sodium ethylate, and we obtain the corresponding triethyl ester. The-benzylsuccinic acid is formed by the triethyl ester reacting with concentrate hydrochloric acid and taking place hydrolyzation and decarboxylation reaction at the same time. In order to avoid the formation of cinnamic acid, the sodium ethylate and diethyl malonate must be react sufficiently. The course has simple operation, inexpensive materials and better yield.

具体制备工艺为：首先以L-苯丙氨酸为原料采用重氮化方法得到-2-氯-3-苯基丙酸，再经酯化得到-2-氯-3-苯基丙酸乙酯后在乙醇钠催化作用下和丙二酸二乙酯缩合，发生SN2反应，得到相应的三乙酯，然后经水解和脱羧，得到-苄基丁二酸；在实验中乙醇钠要和丙二酸二乙酯充分反应，避免生成肉桂酸乙酯；该过程操作简单，原料便宜，产率较高，总收率可达到26.8%。

According to the results of thermodynamic calculations and the flyash-sodium carbonate sintering experiments, contrasting the energy consumption, material resource consumption and the expellant of the greenhouse gas CO2 during the two sintering processes, it demonstrates that the procedure could be the least consumptions of the mineral resources and energy, the least expellant of the greenhouse gas CO2, and that the terminal products with high value could be manufactured when sodium carbonate is taken as the flux agent.

基于热力学计算结果，对比了两种工艺的能耗、物耗、温室气体排放量等因素，结合粉煤灰－碳酸钠烧结反应实验，证明以碳酸钠为配料，高铝粉煤灰烧结过程具有一次性资源消耗量少，能耗最低，温室气体CO2排放量最小，且可生产高附加值产品，实现完全清洁生产等优点。

The by-product sodium salt solution can be reacted with fluosilicic acid to produce sodium fluosilicate with lower cost and no three-wastes are produced in the process.

副产物钠盐溶液与氟硅酸反应还可用于制取氟硅酸钠，使氟硅酸钠的生产成本也较低，且无三废产生。

In the wet-process phosphoric acid production from the Hubei phosphate ore, one of the bothersome problems is that potassium fluosilicate and sodium fluosilicate scales are liable to form on the filtration system owing to its high potassium and sodium content, which greatly restrains the application of Hubei phosphate ore.

本文首先采用人工冷却系统模拟湿法磷酸生产的真空过滤系统冷却过程，研究垢物的析出规律，实验结果得知：垢物的主要成分为氟硅酸钠和氟硅酸钾，氟硅酸钠首先析出，结构致密，其次是氟硅酸钾，最后是二水硫酸钙，氟硅酸钠对氟硅酸钾有很强的结晶诱导作用；然后在三种生产中常用的不同的材质钼二钛、聚氯乙烯和聚四氟乙烯表面进行结垢试验，发现聚四氟乙烯表面最不易结垢，而在钼二钛表面最易结垢。
