标题:基于烷基硫酸盐的质子和非质子离子液体是否对水和酒精稳定热力学方法
摘要:在开发涉及这些新型材料的任何工业应用和方法之前,了解在其他分子(例如水)存在下化学稳定性随离子液体(ils)温度变化的知识至关重要.在较大的温度范围和组成范围内,液相平衡和密度可以提供有关il纯度和化学稳定性的基本信息.Il科学界要求从参考数据中获取准确的测量值.在这项工作中,研究了在水和各种醇(甲醇,乙醇,1-丁醇和1-辛醇)存在下,不同的基于烷基硫酸盐的离子液体的稳定性,以了解它们在高达423.15 K的温度下的稳定性.分别进行水解和酯交换反应.根据这项调查,很明显,基于硫酸甲酯和硫酸乙酯的离子液体在水的存在下不稳定,因为毫无疑问地观测到了硫酸甲酯或硫酸乙酯阴离子水解为甲醇或乙醇和氢化阴离子.这样的观察可以帮助解释不同群体在文献中发表的物理性质的差异.此外,似乎热力学平衡过程驱动了这些水解反应.换句话说,这些水解反应实际上是可逆的,从而提供了通过基于硫酸氢的il与相应的醇(甲醇或乙醇)

摘要:The present invention provides for a method to deconstruct a biomass comprising: (a) introducing one or more individual components of an ionic liquid (IL) or deep eutectic solvent (DES) to a biomass, wherein the one or more individual components, and optionally any components already present in the biomass, form an IL or DES, or mixture thereof, which solubilizes the biomass to form a solubilized biomass mixture, wherein at least one individual component is introduced to the biomass separately from any other individual component; (b) optionally introducing an enzyme and/or a microbe to the solubilized biomass mixture such that the enzyme and/or microbe produces a sugar from the solubilized biomass mixture; and, (c) optionally separating the sugar from the solubilized biomass mixture.

摘要:The present invention relates to a process for chemical conversion of cellulose isolated from aromatic spent biomass to hydroxymethyl furfural using an eco-friendly and economical liquids system with recoverable and reusable solid Indion catalysts and zeolite-phosphomolybdic acid hybrid catalysts. The present invention further relates to the preparation of an effective hybrid catalyst i.e. zeolite-phosphomolybdic acid catalyst for synthesis of HMF. The selectivity and yield of HMF is nearly doubled in zeolite-phosphomolybdic acid hybrid catalyst compared to the individual catalysts (zeolite or phosphomolybdic acid) or combination of catalysts viz. zeolite and phosphomolybdic acid.

摘要:A fine polymer particle production method includes producing an emulsion in a liquid prepared by dissolving and mixing a polymer A and a polymer B in organic solvents in which a solution phase composed primarily of the polymer A and a solution phase composed primarily of the polymer B are formed as separate phases, and bringing it into contact with a poor solvent for the polymer A to precipitate the polymer A. This method serves for easy synthesis of fine polymer particles with a narrow particle size distribution and the method can be effectively applied to production of highly heat-resistant polymers that have been difficult to produce with the conventional methods.
