Effect of alcohol chain length on the optimum conditions for lipase-catalysed synthesis of adipate esters

Immobilized Candida antarctica lipase B, Novozym® 435, was used in the esterification of adipic acid and alcohols with different chain lengths (C1–C18). Optimum conditions for the synthesis of adipate esters were obtained using response surface methodology (RSM) with respect to important reaction pa...
