中文摘要	This paper presents a series of structural modifications of soybean oils for lubricant. The reaction was monitored and products were confirmed by NMR and FTIR. The structural modification is carried out in four stages, (I)synthesis of soybean oil isooctyl ester from soybean oil; (2) synthesis of epoxy-soybean oil isooctyl ester from soybean oil isooctyl ester;(3)synthesis of hydroxylated products from epoxy soybean oil isooctyl ester with fatty acid; (4) esterification of the hydroxylated product with anhydride. Rheological behaviour of the products was measured. Pour points of the products (3) were observed as low as -24 degrees C (lauric acid) and -15 degrees C (isooctanoic acid) respectively. When the hydroxyl groups in the products were esterified with and acid anhydride, the pour points were became higher, which were -21 degrees C (lauric acid) and -6 degrees C (isooctanoic acid) without pour point depr- essant, and -27 degrees C(lauric acid) and-24 degrees C (isooctanoic acid) with 1% of pour point depressant respectively. The products have suitable viscosity and viscosity index, and the viscosity indices are all above 100.
