摘要:具有弱缔合抗衡阴离子的溶剂变色过渡金属(tm)络合物通常用于评估传统的中性溶剂和阴离子的配位能力.但是,在离子液体(il)中使用时,许多常见的假设不再可靠.这项研究研究了在弱溶剂中,Il阴离子在传统溶剂中以及在使用一系列溶剂变色铜络合物的il溶剂中的弱配位能力.[cu(acac)(tmen)] [x](acac =乙酰丙酮酸酯,Tmen =四甲基乙二胺)形式的络合物,其中[x]-= [clo 4]-,Cl-,[no 3]-,[scn]-,[otf] −,[ntf 2已经合成了]-和[pf 6]-并在实验和计算上进行了表征.已经检查了基于这些阴离子以及咪唑鎓和吡咯烷鎓阳离子的il,其中一些被羟基和腈基官能化.已对il-阴离子配位进行了研究,并将其与典型的弱配位阴离子进行了比较.我们发现,在铜中心存在竞争的潜力,传统上被认为是弱缔合的阴离子的情况表明,离子液体中的协调能力

标 题:Synthesis of organohalosilane monomers from conventionally uncleavable Direct Process Residue
发明人：LEWIS KENRICK MARTIN; NEELY JOHN DAVID
权利人:LEWIS KENRICK MARTIN; NEELY JOHN DAVID; MOMENTIVE PERFORMANCE MAT INC
摘要:Disclosed herein is a catalytic process for the synthesis of organohalosilane monomers from tetraorganodihalodisilanes and other compounds that are not cleaved during the conventional hydrochlorination of Direct Process Residue. The process is characterized by the use of a catalyst containing (1) one or more heterocyclic amines and/or one or more heterocyclic ammonium halides, and (2) one or more quaternary Group 15 onium compounds.

摘要:The invention is directed to a simple and new method for the homogeneous synthesis of cellulose ethers. Ionic liquids are not only used as solvent, but also as reaction media for the homogeneous etherification of cellulose. The dissolved cellulose is treated with the etherification agent in the absence of organic and/or inorganic bases and in the absence and/or in the presence of moderate amounts of water. The obtained cellulose ethers show new distributions of substitution on the polymer chain, resulting in new properties and applications.

标题 :Synthesis of organohalosilane monomers via enhanced cleavage of direct process residue
发明人：LEWIS KENRICK MARTIN; NEELY JOHN DAVID
权利人:LEWIS KENRICK MARTIN; NEELY JOHN DAVID; MOMENTIVE PERFORMANCE MAT INC
摘要:Discloses herein is a catalytic process for producing organohalosilane monomers from a high-boiling residue resulting from the Direct Reaction of an organohalide with silicon. The high-boiling residue contains more conventionally cleavable compounds than conventionally uncleavable compounds. The process includes heating the residue in the presence of a catalyst comprising (1) one or more heterocyclic amines and/or one or more heterocyclic ammonium halides, and (2) one or more quaternary Group 15 onium compounds.

摘要:The present invention relates to the manufacture of nitrile compounds from unsaturated organic compounds by reaction with hydrogen cyanide. It relates more particularly to the manufacture of nitrile compounds of use in the synthesis of adiponitrile, an important chemical intermediate in the manufacture of major chemical compounds, such as hexamethylenediamine and ε-caprolactam. The invention provides a process for the manufacture of organic compounds comprising at least one nitrile functional group by carrying out a hydrocyanation reaction between hydrogen cyanide and an organic compound comprising at least one ethylenic unsaturation. This reaction is carried out in the presence of a catalytic system comprising a metal element chosen from the group consisting of nickel, platinum and palladium and an organophosphorus ligand, the reaction medium additionally comprising an ionic liquid in the liquid state at least at the temperature at which the hydrocyanation reaction is carried out.
