甲醛和异戊烯普林斯（Prins）缩合反应的动力学研究
Kinetics of Prins Condensation of Formaldehyde with Isopentene
摘要
Abstract
The Prins condensation intrinsic kinetics of formaldehyde with isopentene was studied with the strong acidic cation-exchange resin as catalyst .The formaldehyde react with isopentene under 2 .0 MPa of N2 pressure and at 333~373 K in a batch reactor .The kinetic model was put forward with a reasonable assumption .The kinetics parameters were obtained using non-linear regression methods .The results show that the positive reaction rate constant and the reverse reaction rate constant are both increased when the reaction temperature increasing .The activation energy is determined as 31 .74 kJ/mol for the positive reaction and 85 .04 kJ/mol for the reverse reaction .The pre-exponential factors of the positive reaction and the reverse reaction is respectively 6 .866 × 103 and 3 .75 × 1010 ;the kinetic model is simulated .关键词
