Article Preview

Abstract:

The catalytic effect of Brønsted acidic ionic liquid for PET hydrolysis reaction under microwave irradiation has been investigated through orthogonal experiment in this article, and the influence of main reaction conditions has also been studied. The results shown that the influence level sequence of reaction factors was: catalyst kind > reaction time > reaction temperature > catalyst dosage. According to a further study of catalyst dosages influence on PET depolymerization degree, the optimal reaction condition was finally concluded as below: [Hexanemi [HSO4] used as catalyst, catalyst dosage: 0.01 mol/2 g PET, reaction time: 210 min, reaction temperature: 195 °C.
