摘要
以十二醇、十四醇、十六醇和α-甲基丙烯酸为原料,甲苯为溶剂,对甲苯磺酸为催化剂,对苯二胺为阻聚剂,酯化生成α-甲基丙烯酸混合酯;再以过氧二苯甲酰为引发剂,合成聚α-甲基丙烯酸混合酯。与其他降凝剂复配后,对高含蜡的泰州柴油具有良好的降凝效果,在加剂量为1 000μg/g时,冷滤点降低了7℃。
Using 12 alcohol, 14 alcohol,16 alcohol and α- methylacrylic acid as raw materials, methyl benzene as solvents,pmethyl benzenesulfonic acid as catalyst , p -phenylenediamine as inhibitor, α -methacrylic acid mixed ester was prepared by esterification, then using dibenzoyl peroxide as initator , poly ( α - methyl acrylic acid) mixed ester was synthesized. The mixed ester compounded with other pour point depressant has good pour point depression effect for Taizhou diesel , when dosage of compound depressant is 1 000μg/g, the cold filter plugging point of Taizhou diesel can be depressed 7 ℃.
