Using Novo435 lipase as catalysis and tert-butanol as medium,four glucose fatty acid esters were directly synthesized from glucose and iso-pentanoic acid,n-hexanoic acid,n-octanoic acid,and lauric acid separately.

The result showed that the yield of glucose stearate could be 89 % under optimum reaction conditions as follows: molar ratio of stearic acid to glucose was 1.
