摘要: 在甲苯溶剂中引发聚合,由物质的量比6∶1∶2的丙烯酸十八酯、马来酸酐、苯乙烯合成降凝剂A,由物质的量比为6∶1∶2的丙烯酸十八酰胺、马来酸酐、苯乙烯合成降凝剂B。在甲苯溶剂中,120 ℃条件下用十八胺和十八醇分别对降凝剂A,B进行醇解和胺解合成降凝剂C和D。以大庆原油为样本考察了A,B,C,D的降凝和降粘效果。在大庆原油中加入质量分数0.5%的降凝剂进行测试,结果表明降凝剂C,D在降凝和降粘上都优于降凝剂A,B。复配性降凝剂C+D在降凝和降粘效果上高于降凝剂C,D。降凝剂C+D的复配质量比为3∶1时,可使大庆原油凝点降低15℃,粘度降低58.38%。

Abstract: By the way of initiated polymerization in toluene solution,two tercopolymers were prepared from octadecyl acrylate(acrylamide),maleic anhydride and styrolene in molar ratio 6∶1∶2 as pour point depressant A(B),C(D),akind of pour point depressant,was synthesized by alcoholysis (aminolysis) of A(B) by stearyl alcohol(octadecylamine) in the toluene as solvent at 120 ℃.The drop effect of pour point and viscosity of A,B,C and D for the sample to Daqing crude oil was investigated.The study was tested by adding the pour point depressants A,B,C,D to high pour point crude oil of Daqing at a dosage of 0.5%,respectively.The results suggest that the pour point depressants of C & D are more effective than A & B,meanwhile,the combination C+ D is more effective than C and D.After adding C+D in mass ratio 3∶1 to Daqing crude oil, its pour point is lowered by 15℃ and viscosity could be reduced by 58.38%.
