  摘要：

  制备了一系列亲水性的N，N-二甲基吡咯烷鎓和N，N-二甲基哌啶基离子液体（ILs），并将其用作Wacker中的反应介质氧化作用 的 苯乙烯 经过 过氧化氢 使用 氯化钯2 作为 催化剂。将这些IL的效率与亲水性和疏水性进行了比较咪唑鎓 系统（包括具有 腈功能）。离子液体的性质强烈影响产物的分布。特别是在疏水性IL中，1,3-二苯基-1-丁烯 产生于 苯乙烯 二聚化 被检测到，除了预期的 苯甲基酮。的形成1,3-二苯基-1-丁烯 可能归因于 钯（0） 来自“氯醇”（可能是在 瓦克工艺）的副反应。因此，IL能够促进或不利于“氯醇“ 到 ”ClPdOOH“ 经过 过氧化氢给出均相或双相系统的化合物，似乎是影响选择性的主要因素。

  Dissolving-grade pulp compositions are prepared by treating a cellulosic material with an extractant comprising a cellulose solvent and co-solvent. The dissolving-grade pulp compositions comprise at least 90 wt. % glucan, from 0.6 to 5 wt. % xylan, and have distinct molecular weights, and elemental metal ions from known and commercially available dissolving-grade pulp compositions.

  Hemicellulose compositions are prepared by treating a cellulosic material with an extractant comprising a cellulose solvent and co-solvent. The hemicellulose compositions preferably comprise from 55 to 99 wt. % xylan and have distinct molecular weights, elemental metal ions, and intrinsic viscosities when compared to known hemicellulose compositions.

  A process for treating a cellulosic material comprising pretreating the cellulosic material and then extracting the cellulosic material with an extractant to selectively extract hemicellulose therefrom and separating the extracted hemicellulose to form a cellulosic product comprising less hemicellulose than the cellulosic material. The extractant comprises a cellulose solvent and a co-solvent. The cellulosic product advantageously retains its cellulosic fiber morphology. The processes involve separating and recovering the hemicellulose and separating and recycling various process streams employed in the process.
