Abstract
Diisononyl adipate is a plasticizer which has excellent property of low temperature resistance and is permitted in food contact materials. In this study, diisononyl adipate was synthesized from adipic acid and isononyl alcohol in a solvent-free system via immobilized lipase-catalyzed esterification. Liquid Eversa lipase from Thermomyces lanugutosus was immobilized on Lewatit VP OC 1600 carrier. The effects of temperature, substrate molar ratio, water activity of enzyme, vacuum, and enzyme loading on the reaction efficiency were investigated. Application of vacuum played a key role to achieve a 100% conversion. The optimal temperature, molar ratio (adipic acid to isononyl alcohol), water activity of enzyme, vacuum were 50 degrees C, 1:3, 015, 13.3 kPa, and 10% (based on weight of total substrate). Under these conditions, 100% conversion was achieved within 6 h.
