Steps:

1-4 Example 2
Oleic acid-based ionic liquid microemulsion components and their amounts: 1.4 parts by weight [Bmim]BF4,40.5 parts by weight of oleic acid,21.9 parts by weight of Triton X-100,4.8 parts by weight of 1-octyl-3-methylimidazolium hydrogensulfate, 31.4 parts by weight of n-butanol; At 28 ° C, The Triton X-100 and 1-octyl-3-methylimidazolium hydrogensulfate mixed, stir at 400 rpm, stir for 8 minutes to obtain a clear and transparent mixture, and then add oleic acid and n-butanol. The mixture was stirred at a speed of 400 rpm and stirred for 10 minutes to obtain a clear and transparent mixture. [Bmim] BF4 was added dropwise to the mixture and stirred for 5 minutes to obtain a clear transparent oleic acid based ionic liquid microemulsion. 51 g of oleic acid-based ionic liquid microemulsion was taken, and the esterification reaction was carried out under a nitrogen atmosphere with heating and stirring, wherein the stirring speed was 600 rpm, the reaction temperature was 100 ° C, and the reaction time was 8 h. After the completion of the reaction, petroleum ether was added to extract the target product, and the petroleum ether mixture containing the target product was rotary-screwed to obtain a product. The yield of butyl oleate was 95.2% and the oleic acid conversion was 97.1%.The selectivity is 98.0%.
