Synthesis of n-dibehenyl fumarate-vinyl acetate copolymers and their effects on pour point depression and viscosity reduction(富马酸长链酯与醋酸乙烯酯共聚物的合成表征及其降凝降粘作用研究)
以对-甲苯磺酸为催化剂,甲苯为溶剂,用直接酯化法制备富马酸双混合醇酯单体(DBF).游离基聚合合成富马酸双混合醇酯与醋酸乙烯酯共聚物(FVA).单体及共聚物用IR1,H-NMR表征,并考察共聚物对高蜡、高粘原油、渣油及白油、光缆油的降凝降粘作用.在一定条件下合成得到的聚合物可使华北油田高蜡原油降凝21 ℃ ;克拉玛依稠稀混合油(60:40)降粘75.24%(5 ℃),73.61%(10 ℃),69.95%(15 ℃);大庆渣油降凝13 ℃,降粘42.1%(40 ℃);新疆彩南原油降粘48.21%(10 ℃),53.69%(15 ℃);对白油、光缆油也有一定的效果....
