Abstract:
Geraniol esters were synthesised by direct esterification catalysed by esterases and lipases (five enzymes were tested) in a solvent-free system at 37 degrees C. The best conversions yields, about 85%, on geranyl butyrate and valerate obtained with esterase 30000 from Mucor miehei. The effect of substrate molar ratio alcohol/acid variation was studied. A study of the water production was made in parallel during the esterification reaction.
