    摘要:
    一系列烷基三亚甲基膦氯化物离子液体,由三亚甲基膦和相应的1-氯烷烃(CnH2n+1Cl,其中n = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12或14)制备而成。本工作的焦点在于可变链长如何影响物理性质,如熔点/玻璃化转变、热稳定性、密度和粘度。通过QPSR相关性和基团贡献方法解释了实验密度和粘度数据。我们首次展示了离子液体的经验交替效应的实例。

    2,3-dichlorobutadiene-1,3 of high purity is produced from 1,2,3,4-tetrachlorobutane by a process comprising the steps of dehydrochlorination, chlorination of the reaction product obtained in the dehydrochlorination step and subsequent separation of a 2,3-dichlorobutadiene-1,3 composition from the reaction product of the chlorination step.
    高纯度的2,3-二氯丁二烯-1,3是通过从1,2,3,4-四氯丁烷中经过脱氯化、氯化脱氯化步骤得到的反应产物进行氯化,然后从氯化步骤的反应产物中分离出2,3-二氯丁二烯-1,3组成的过程来生产的。

    One main limiting factor for the technoeconomics of future bioprocesses that use ionic liquids (ILs) is the recovery of the expensive and potentially toxic IL. We have demonstrated a new series of phase‐separable ionic liquids, based on the hydrophobic tetraalkylphosphonium cation ([PRRRR]+), that can dissolve lignin in the neat state but also hemicellulose and high‐purity cellulose in the form of
    使用离子液体(IL)的未来生物过程的技术经济学的一个主要限制因素是昂贵且潜在有毒的IL的回收。我们已经证明了一系列基于疏水四烷基alkyl阳离子([ PRRR ] +)的可相分离的离子液体,该液体可以以纯净状态溶解木质素,但也可以以电解质溶液的形式溶解半纤维素和高纯度纤维素。与偶极非质子溶剂一起使用。例如,IL三辛基甲基乙酸acetate([P 8881[OAc])在添加40 wt%的DMSO的情况下,在60°C时最多可溶解19 wt%的微晶纤维素(MCC)。发现MCC饱和点取决于溶液中DMSO和IL的摩尔比。在最佳饱和度下,摩尔比约为1:1 [P 8881观察到[OAc]为脱水葡萄糖单元,这表明高效溶剂化。在Lindman假设的背景下,这归因于这些更多的两亲阳离子-阴离子对的积极贡献。MCC上的溶液状态HSQC NMR光谱进一步说明了这种有效的溶解。最后,还证明了通过添加水溶液这些电解质

    According to a production process, aromatic ethers are producible by reacting phenols with an oxirane compound with use of an anion exchange resin as a catalyst. According to another production process, aromatic ethers having an alcoholic hydroxyl group are producible by a crystallization-purification step of using a solvent having a solubility parameter ranging from 7.5 to 12.5 for purification by crystallization. Further, according to still another production process, producible are aromatic ethers having an alcoholic hydroxyl group, wherein the content of a metal in the aromatic ethers is less than 100 ppm by mass, and the content of a halogen element in the aromatic ethers is less than 100 ppm by mass.

    Purified chlorinated alkenes are produced by a process in which a mixture of i) a first chlorinated alkene that has at least one beta-chlorine substituent and no alpha-chlorine substituents and ii) a second chlorinated alkene that has at least one alpha-chlorine substituent is contacted with chlorine in an amount sufficient to further chlorinate the second chlorinated alkene, but which is insufficient to cause conversion of more than 20% of the first chlorinated alkene. The resultant reaction product may be easily enriched to provide a chlorinated alkene product wherein a) the weight percentage of chlorinated alkenes having at least one beta-chlorine substituent and no alpha-chlorine substituents, based on the total weight of the chlorinated alkenes present in the enriched chlorinated alkene product compared to b) the weight percentage of chlorinated alkenes having at least one beta-chlorine substituent and no alpha-chlorine substituents, based on the total weight of the chlorinated alkenes present in the mixture prior to chlorination is increased by at least 0.25 wt. %.
