It was generally synthesized with the methods described in literatures (9) and (10) in China, while in foreign countries, azelaic acid was mainly prepared with the methods described in literatures〔11〕and 〔12〕.

国内一般利用文献〔9，10〕的方法制备，而国外近年来主要以文献〔11，12〕的方法获得壬二酸，另外，还出现了以煤和工业废料为原料获取壬二酸的报道〔13〕。

On the condition of using fatty acids of rapeseed oil as raw material,85% acetic acid as solvent, pelargonic acid as recrystalization solvent, this paper prepared azelaic acid and brassylic acid by ozonolysis ,oxidation decomposition ,recrystallization etc.

以蓖麻油酸为原料、85%醋酸水溶液为溶剂，经臭氧化、氧化分解、沸水萃取等过程制备壬二酸的最佳反应条件为：m：m(85%醋酸)=1：4，臭氧化温度20-25℃；氧化分解温度90-95℃，催化剂醋酸锰/醋酸铜用量为原料蓖麻油酸质量的0.09%，氧化分解4h，壬二酸的收率为62.5%。

It is seen that oxygen group function of additives is very remarkably in tribological characteristics, that is EP property of dihydroxy docosanoic acid without active element is very near to that of SO with active element sulfur.

双羟基廿二酸的极压性与不含氧基团的硫化烯烃十分接近，以液体石蜡为基础油，最大无卡咬负荷P〓值，前者为539N，后者为588N，再者相差49N，可以看出，氧基团的作用是十分显著的，即无活性元素的双羟基廿二酸的极压性可以十分接近于含活性元素的抗磨极压剂硫化烯烃。
