ABSTRACT
This work enlarge the study of the enzymatic hydrolysis mediated by ultrasound
primary, secondary and tertiary acetates models.
The substrates used in this reactions were: 1-methylpentyl acetate, 1-
methylhexyl acetate, 1-methyloctyl acetate, 1,5-dimethyl-4-hexenyl acetate, 1-butyl-2-
propenyl acetate, 2-ethyl-hexyl acetate, 1-isobutylpentyl acetate, 1-phenyletyl acetate,
ciclohexyl(phenyl)methyl acetate, 1,2,3,4-tetrahydro-1-naphthalenil acetate and 1-
methyl-1-(5-methyltetrahydro-2-furanyl)ethyl acetate. Some alcohols prepared by these
enzymatic hydrolysis are pheromones (sulcatol, 2-methyl-4-octanol, 1-phenylethanol
and 2-(5-methyltetrahydro-2-furanyl)-2-propanol), which can be used in the control of
insects. The enzymes valued in these reactions were: pig liver esterase (PLE), Candida
rugosa lipase (CRL) and Aspergilus oryzae protease (AOP).
In general way, the use of ultrasound bath lead to an appreciative decrease in the
reaction time of enzymatic hydrolysis reactions for alkyl and aryl acetates when
compared with the use of magnetic stirring in the same reactions, excepting when PLE
was used. in enzymatic hydrolysis of the 1-isobutylpentyl acetate.
