Two kinds of high alcohol acrylates were prepared by octadecyl alcohol and hexadecyl branched alcohol,respectively.The polymers of depressants were prepared by maleic anhydride-styrene-higher alcohol acrylates.By using these depressants,the pour points of the Liaohe crude oils were lowered form 30℃ to 20℃.

分别采用碳十八直链醇、碳十六支链醇与丙烯酸合成烷基酯，将烷基酯再与顺丁烯二酸酐、苯乙烯聚合制备的三元共聚物，对辽河油田的高凝原油的降凝效果进行了评价，实验发现这两种聚合物对凝固点为30℃原油都具有较好的效果，降幅可达10℃左右，但对凝固点为41℃的原油较差分别为3℃和6℃。

The results show that the optimal parameters of esterification are as follows: 4% of SO42-/ZrO2, molar ratio of methanol to litsea cubeba kernel oil 101, 68 ℃ of reaction temperature and 4 h of reaction time, the acid value decreases to 2.52 mg/g. Compared with the traditional acidic-catalyzed method, this method has the advantages of no acid proof equipment, easy to recycle catalyst and no acidic waste water emission. The optimal parameters of transesterification are as follows: 25 ℃ of reaction temperature, 0.5% of hexadecyl-trimethyl-ammonium bromide, 1% of NaOH, molar ratio of methanol to the oil 61 and 15 min of reaction time. The ester exchanging rate is 97.6%. This method adopts phase transfer catalyst and produces industry prospect, which has many advantages such as energy-saving and time-saving under room temperature.
