Description:
The Diels-Alder Reaction (DAR) between N -ethylmaleimide and 2,3-dimethyl-1,3-butadiene was studied in microemulsions with ionic liquid (IL) for the first time. The apparent second-order rate constants were determined by spectrophotometry in the microemulsion. The effect of solvent on the DAR rate was investigated and interpreted. The experimental results showed that the reaction rate in the microemulsion with IL was enhanced and it was faster than that in pure isooctane and in generic AOT microemulsion. The effect of the IL on the apparent second rate constant ( k 2 ) was explained. The effect of temperature on the reaction rate was studied, and values of apparent activation energy were estimated in various microemulsion with IL. Copyright © 2012 John Wiley & Sons, Ltd.
