Kinetic study and reactivity trends of hydroxide ion attack on some chromen-2-one laser dyes in binary water-methanol and water-acetone mixtures
The kinetics of base-catalyzed hydrolysis of 7-dimethylamino-4-methyl-2_H_-chromen-2-one (DMAC) and 7-diethylamino-4-methyl-2_H_-chromen-2-one (DEAC) in binary water-methanol and water-acetone mixtures were studied in the temperature range from 288 to 313 K. The activation and thermodynamic parameters of these reactions were evaluated and discussed. The change in the activation energy in going from water to aqueous methanol and aqueous acetone was estimated from the ... Read more
