介绍了分别选用碳十二醇、碳十四醇、碳十六醇和碳十八醇为原料合成聚丙烯酸高碳醇酯类降凝剂的方法,选择了最佳合成条件。并评价了这四种聚丙烯酸高碳醇酯降凝剂对大庆0号柴油的降冷凝点和降冷滤点的效果,得出聚丙烯酸十六醇酯降凝剂的降冷滤点和降凝点的综合效果较好,与国外同类产品比较,在降冷滤点方面尤其具有一定的优势。
The methods of synthesizing poly (acrylic acid) high alcohol ester pour point depressant by using carbon dodecanol, carbon tetradecyl alcohol, carbon cetyl alcohol and carbon octadecanol as raw materials are introduced respectively, and the optimum synthesis conditions are selected. The effects of the four polyacrylate polycarboxylate pour point depressants on the lowering and freezing points of Daqing No. 0 diesel oil were also evaluated. The results showed that the pour point and descending temperature of the cetyl polyacrylate pour point depressant The combined effect of freezing point is better, compared with similar foreign products, especially in the cooling filter point has some advantages.
