Among the plasticisers added to PVC polymer are DEHA and DOA, not part of the phthalates family.

在plasticisers增加聚氯乙烯聚合物和DOA是DEHA ，而不是部分邻苯二甲酸盐的家庭。

By esterification, saponification, doubledecomposition and formulation, liquid rare earth of monoisooctyl phthalate complex heat stabilizer was prepared with phthalic anhydride, isooctyl alcohol, sodium hydrate, rare earth chloride, mixed solvent and other reagents. The optimum conditions are: the temperature of esterfication is 130～140℃,and the reaction time is 1h. The temperature and time of saponification is 60℃ and 10min respectively. The temperature of double decomposition is 60～70℃,and the reaction ti...

摘 要：以邻苯二甲酸酐、异辛醇、氢氧化钠、氯化稀土、混合溶剂、助剂为原料，通过酯化反应、皂化反应、复分解反应以及复配制备了以邻苯二甲酸单异辛酯稀土为主要成分的液态稀土复合热稳定剂，其工艺条件为：酯化反应的温度控制在 130～ 14 0℃，反应时间为 1h ；皂化反应的温度为 6 0℃，反应时间为 5min ；复分解反应的温度在 6 0～ 70℃，反应时间为 1h ；水洗温度控制在 6 0～ 6 5℃；混合溶剂的用量为 5 0 %，稀土含量为 6 0 3%；在复配过程中，采用亚磷酸酯作为辅助热稳定剂，其用量为 5 %～ 7%，PVC中加入 2 %的这种稀土复合热稳定剂，在185℃下，其热稳定时间为 4 5min。

In the key support's project may see from the plan, products and so on refinery, ethylene, xylene, fine dicarboxylic acid, chemical fertilizer, alkene receive the direct support.
