Production of polyurethane is increasing since the recent years. Nevertheless, this production uses hazardous chemicals, which is isocyanate. Academy has put a lot of effort to develop some non-isocyante polyurethane routes. One of the most promising is the aminolysis of cyclic-carbonate by diamine. To industrialize this way of production, kinetic and thermodynamic data are needed. The first steps were to optimize the production of methyl oleate, epoxidized methyl oleate and carbonated methyl oleate. Then, a kinetic model was built for a model reaction which is the aminolysis of carbonated methyl oleate by n-butylamine by taking into account the side reaction of amidation. The model fits correctly the experimental data. A Tian-Calvet calorimeter was used to determine the different reaction enthalpies. It was found that the reactions of aminolysis and amidation were few exothermic.

环状碳酸酯植物油的氨解作为非异氰酸酯合成聚氨酯的途径:动力学和热学研究

自最近几年以来,聚氨酯的产量正在增加。然而,这种生产使用的是有害化学物质,即异氰酸酯。学院为开发一些非异氰酸酯聚氨酯路线付出了很多努力。最有前途的方法之一是二胺对环状碳酸酯的氨解作用。为了工业化这种生产方式,需要动力学和热力学数据。第一步是优化油酸甲酯,环氧化的油酸甲酯和碳酸的油酸甲酯的生产。然后,通过考虑酰胺化的副反应,建立用于模型反应的动力学模型,该模型反应是碳酸化的油酸甲酯被正丁胺氨解。该模型正确拟合了实验数据。使用Tian-Calvet量热计确定不同的反应焓。
