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 ice/liquid mixtures of the coolant and the sample solution were respectively added in the Dewar bottle and the sample container to precool for 2~3 hours under stirring. Then some of the coolant liquid was replaced with coolant ice, the motor stirrer was restarted, and the temperatures were read from the Beckmann thermometer.

实验时，先调节寒剂的组成使其凝固点低于待测溶液的凝固点～2℃，然后分别在保温瓶和凝固点杯中加入寒剂和待测溶液的冰水，启动搅拌器预冷却2~3小时，接着更换保温瓶中的寒剂冰水，重新启动搅拌器，记录贝克曼温度计读数。

A device for determining molar mass with freezing point depression was improved,which consists of the Dewar bottle,sample container,Beckmann thermometer,and motor stirrer.
