| Abstract: |
| A new esterification equipment of combining microwave heating and water separation from azeotropic rectification solves the problem of the reaction quickly under the condition of microwave but water separation slowly. This equipment can synthesize butyl ester rosin within 2 hours.The effect of the reaction substance's ratio,microwave power and the catalyzer dosage on the reaction process is discussed. |
| Key words: azeotropic rectification microwave butyl ester rosin esterification |
