改性核/壳型苯丙乳液及油水分离性能
|
摘要
以苯乙烯(St)、丙烯酸丁酯(BA)为单体,丙烯酸(AA)为功能单体,乙烯基三异丙氧基硅烷作为改性剂,过硫酸铵(APS)为引发剂,合成了一种非聚醚型破乳剂(S-B-A)。最佳工艺条件:反应温度为78℃,复合乳化剂质量分数(占单体总质量)为4%,m(St)∶m(BA)∶m(AA)=20∶19∶6,并与常规破乳剂聚酰胺-胺型树枝状高分子(PAMAM)复配。对2种不同破乳剂的温度、沉降时间、复配比、亲水亲油平衡点(HLB)、界面张力(IFT)的影响进行了详细研究。结果表明,脱水率达96.2%(质量)以上,满足工业要求。
A non-polyether demulsifier( S-B-A) is synthesized by using styrene( ST) and butyl acrylate( BA) as monomers,acrylic acid( AA) as functional monomer,vinyl tri-isopropoxysilane as modifier,ammonium persulfate as initiator.The optimum synthesis conditions are as follows: the reaction temperature is at 78℃,the mass concentration of compound emulsifier is 4%,m( ST) ∶ m( BA) ∶ m( AA) = 20 ∶19 ∶6.The S-B-A demulsifier is complexed with conventional demulsifier polyamide-amine polymer( PAMAM).The effects of temperature,coagulation time,complex ratio,hydrophilic affinity balance and interfacial tension on two kinds of demulsifiers are studied in detail. By optimizing the operating conditions,the dehydration rate can reach 96. 2%( wt.),meeting the industrial requirements.
