摘要:我们目前的1 H,13 C和15个ñNMR的散装离子液体化学位移基于1-丁基-3-甲基咪唑(阳离子也称为1-丁基-3-甲基吡啶)卤化物(氯-,溴-和我-)和三溴化(br 3-)的盐.在类似的icl溶液a表征2-和我3-盐也有报道.基于一些选定的超分子离子聚集体,已进行了一系列dft计算以预测纯il的NMR光谱特征.为了仅测试氯化物盐的温度,振动和构象运动的影响,我们还使用admp方案(原子中心密度矩阵传播分子动力学模型)对气相离子对进行了第一性原理分子动力学模拟. ).我们研究的目的是测试一种简单的基于dft的离子液体中离子对方法是否能够提供可靠的结果,以及在什么条件下该方案是可靠的.我们在三种卤化物的计算光谱和实验光谱之间获得了很好的一致性,−阴离子(x = Cl,Br和i)和吡啶鎓环的原质子(结构安排与卤化吡啶鎓的固态结构没有太大不同).与此相反,当h-键较弱,如在br 3

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.

摘要:“Frozen ionic liquidâ€? microparticles and nanoparticles are disclosed, as are alternative methods of making the particles. The particles may be monodisperse or polydisperse, with spherical or other shapes. The particles may be prepared without specialized equipment, and without harsh conditions. The microparticles and nanoparticles have uses in biomedical, materials, analytical, and other fields.
