标题:Effects Of Halide Anions To Absorb So2In Ionic Liquids
摘要:制备了含有卤化物阴离子的离子液体,并研究了卤化物阴离子对离子液体$so_2$溶解度的影响.研究表明,离子液体的$so_2$溶解度在$so_2$/ils 摩尔比 1.91~2.22 之间.$so_2$ 在不同卤化物阴离子的离子液体中的溶解度遵循 Br > Cl > I 的顺序.通过对 $so_2$ 和 [emim]X(其中 X = Cl,Br 和 I)之间相互作用的理论研究,提出了卤化物的主要相互作用发生在咪唑鎓的 $c_2$-H 和 $so_2$ 的 S 上.实验结果进一步表明,$50^{\circ}C$的吸收和$140^{\circ}C$的解吸是可逆的.傅立叶变换红外研究证实了 $so_2$ 吸收的可逆性.

摘要:A solution phase synthesis process for preparing a rare earth perovskite, the process includes reacting an alkali metal material with a first surfactant ligand in the presence of a first solvent to obtain a first precursor complex solution; reacting a rare earth metal halide with a second surfactant ligand in the presence of a second solvent to obtain a second precursor complex solution; and reacting the first precursor complex solution with the second precursor complex solution in the presence of a third surfactant ligand and a third solvent to obtain the rare earth perovskite; wherein: the rare earth perovskite is in the form of nanocrystals; and the first solvent and third solvent comprise a non-coordinating solvent.

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.
