摘　　要：筛选了一种对EVA具有优良溶解性的混合溶剂,当其溶解质量分数为8%的EVA后,自身凝点为6℃,闪点为65℃。通过正交实验表明:当EVA质量分数为8%、油酸酰胺质量分数为2%、FC-03质量分数为5‰、混合溶剂质量分数为89.5%,加入量为1000 mg/kg时,使原油的凝点由35℃降低到14℃。A mixed solvent, which had an excellent solubility towards EVA, was explored.When the solvent dissolved a mass fraction of 8%EVA, its freezing point was 6℃, and the flash point was 65℃.Through the orthogonal experimental, experimental results showed that when the mass fraction of EVA was 8%, the mass fraction of FC-03 was 5‰, the mass fraction of preparation of oleamide was 2%and the mass fraction of mixed solvent was 89.5%, the freezing point of crude oil reduced to 14 ℃from 35 ℃as the pour point depressants amount reached 1000 mg/kg.
