![عکس صفحه اول مقاله: Kinetics of enzymatic synthesis of geranyl butyrate by transesterification in various supercritical fluids Kinetics of enzymatic synthesis of geranyl butyrate by transesterification in various supercritical fluids](/preview/png/3953.png)
The transesterification of methyl butyrate, ethyl butyrate and butyl butyrate to geranyl butyrate was investigated in supercritical carbon dioxide. The effect of chain length of the butyrate on the rate of transesterification was investigated. The initial rates followed the trend: ethyl butyrate < butyl butyrate < methyl butyrate. The transesterification of butyl butyrate to geranyl butyrate in various supercritical fluids such as ethylene, methane, ethane was also examined. The initial rate of transesterification of butyl butyrate in different supercritical fluids followed the order: ScCO2 < ScC2H6 < ScC2H4 < ScCH4. The highest initial rate was obtained in supercritical methane and the reasons for this observation were proposed. The Ping-Pong Bi–Bi model with inhibition by both acid and alcohol was used to model the experimental data and determine the kinetics of the reaction.
