阳离子型破乳剂组分C的合成及配方优选

The synthesization and optimization of cationic demulsifier C

为促进原油破乳,提高脱水率,在室内合成了一种阳离子表面活性剂组分C,并分析了合成过程中的影响因素。结果表明:采用过硫酸盐-脂肪胺引发体系时,共聚反应易控制,获得的共聚物特性黏数天,残余单体含量少;提高共聚物的特性粘数,可以提高原油脱水率,但增加幅度不大,当阳离子单体二甲基二烯丙基氯化铵(DC)的质量浓度为0.03g·L^(-1)时,脱水率最高。

In order to promote the crude oil demulsification and improve dewatering ratio, we have synthesized a kind of cationic surfactant C in the lab. The synthesization's effective factor was analyzed. Results show that when persulfate-aliphatic amine initiating system is applied, combining reaction can be controlled easily, we can get high performance viscosity of copolymers, and the content of relic monomers is little. By increasing the performance viscosity of copolymers, we can enhance dewatering ratio of oil, but the incensement is not large. When the adding quantity of monomer dimethyldiallylammonium chloride(DC) is 0. 03g. L-1 , dewatering ratio is highest.
