Esterification of acetic acid with alcohol isoamyl in the presence of enzymatic catalyst
The Candida antarctica Lipase B immobilized on polyurethane catalysed esterification of acetic acid with isoamyl alcohol in mechanical and ultrasonic system in a system solvent-free, was studied. The maximum esterification of isoamyl acetate used immobilized catalyst was the highest esterification,...
