摘要:在这项工作中,我们报告了离子液体对一类电荷中性亲核试剂的影响.我们研究了 (N) 丁胺,二 (N) 丁胺和三 (N) 丁胺与对硝基苯磺酸甲酯在 [bmpy][n(Tf)(2)],[bmpy][otf] 中的反应和 [bmim][otf](bmpy = 1-丁基-1-甲基吡咯烷鎓;bmim = 1-丁基-3-甲基咪唑鎓)并将它们的反应性 K(2) 与分子溶剂二氯甲烷中相同反应的反应性进行比较和乙腈.结果表明,所有胺在离子液体中比在本工作中研究的分子溶剂中更具亲核性.还与离子液体对氯离子反应性的影响进行了比较,氯离子在离子液体中失活.eyring 激活参数表明,激活熵的变化是造成所见效果的主要原因.这可以部分解释为不同的氢键性质,如 Kamlet-Taft 溶剂参数所示,这些溶剂中的每一种以及溶剂和亲核试剂之间氢键的形成.

摘要:The present invention relates to a method for the depolymerization of a polyurethane mass, preferably thermoset polyurethane. The method comprises four main steps: i) mixing the polyurethane mass with a depolymerization reaction medium comprising an ionic liquid in a proportion equal to or greater than 50% w/w with respect to the total weight of said medium, a superbase as a catalyst, and a nucleophilic agent in a proportion equal to or less than 15% w/w with respect to the total weight of said medium, subjecting said mixture to a temperature between 50-100°C for between 2 minutes and 10 hours; ii) adding a mass of a protic molecular solvent in an amount between 4 and 40 times the weight of the depolymerization reaction medium; iii) subjecting the mixture from step ii) to a temperature between 20-60°C for at least 1 hour; and iv) separating the fractions obtained in step iii), namely, a semisolid fraction comprising at least a polyol mass for reuse in the synthesis of a new polyurethane, and a single-phase liquid fraction comprising at least the ionic liquid and the basic catalyst, for their reuse in a new process for polyurethane depolymerization.
