fluoride and butyrate it occurred to us that since butyric acid greatly inhibits the hydrolysis of ethyl butyrate sodium butyrate.

Catherine is studying the hydrolysis of ethyl butanoate; In a different reaction Catherine wants to make butyl ethanoate.
Effect of ptI on the rate of hydrolysis of tributyrin and ethyl butyrate by milk. ]ipases. which was hydrolyzed between the pH of 5.7 and 6.0.
the hydrolysis reactions of aroma compounds with hydrolyzable functional groups In particular a significant number of aroma compounds contain carboxylic acid ester moieties which can participate in various acid- and base-catalyzed and neutral hydrolysis mechanisms [8-10] For example of the 738
hydrolysis of C-4 ethyl ester where no aggregation occurs In the C-5 to C-8 experiments ester-containing micelles (ECM) are mainly formed by cooperative aggregation of alkanoate anions with ester molecules ECM is formed only after a threshold concentration of the alkanoate anion has been reached In a phase-
to synthesize ethyl butanoate from tributyrin and ethanol; none of these lipases could produce ethyl butanoate from butanoic acid and ethanol under similar conditions (data not shown) Figure 2 shows the impact of a w and NaCl on ethyl butanoate synthesis by Palatase from ethanol and tributyrin Lowering the a w from 0 99 to 0 83 moderately
The effects of temperature ethanol concentration and pH on the rate of hydrolysis of common volatile esters of wine (ethyl butanoate ethyl hexanoate ethyl octanoate ethyl decanoate isobutyl acetate isoamyl acetate hexyl acetate and 2-phenylethyl acetate) were investigated in model situations
