Abstract：Polyoxometalates supported by metal-organic frameworks (MOFs) were synthesized and used as catalysts in the one-pot oxidative esterification of glycerol. Reaction conditions were as follows: pH value was 8, catalyst loading was 8%, and the reaction time was 24 hours. A yield of 48.6% was obtained, and the selectivity of esters was 34.5%. The whole process was sustainable and mild, and catalysts could be recycled. The recyling of the by-products of biodiesel could be achieved. Studies on the catalytic factors and mass transfer of MOFs were carried out. The process was analyzed.

Key words：glycerol; oxidative esterification; metal-organic frameworks; mass transfer
