Abstract
Abstract The bioconversion of waste C1 gases into formic acid and hexanol is highly important for the sustainable synthesis of diverse chemicals from non-petrochemical sources and the reduction of greenhouse gas emissions. Herein, we valorized formic acid and hexanol by subjecting them to lipase-catalyzed esterification to afford hexyl formate. The maximum conversion was 98.28% with Novozym 435 of 15 g/L, a formic acid to hexanol molar ratio of 1:5, a reaction temperature of 40 °C, and with 1,2-dichloroethane as a solvent for 1.5 h. The original enzymatic activity was retained even after 20 cycles, while conversion was maintained above 95%. These results may generally contribute to the lipase-catalyzed synthesis of formate esters and be used to efficiently valorize waste C1 gases into short-chain flavored esters.
