Lipase-Catalyzed Synthesis of Cetyl Palmitate in the Presence of n-Hexane and Ethyl Ether

Figure 3

Effect of temperature on the esterification of palmitic acid with cetyl alcohol using n-hexane as solvent. (□ – –) 37.5°C; (△ —) 55°C. Reaction conditions: stirring speed of 600 rpm, initial molar ratio of cetyl alcohol to palmitic acid of 1 : 1, catalyst loading of 1 wt% (in relation to the mass of substrates), and n-hexane to substrates’ mass ratio of 1 : 1.
