  Phenoxy herbicidal ammonium ionic liquids

  摘要：

  Ammonium ionic liquids with the 4-chloro-2-methylphenoxyacetate anion were synthesized and characterized. Physicochemical properties, such as thermal stability, phase transition temperatures, viscosity, density, refractive index, as well as surface activity and herbicidal activity were determined. Improved physicochemical properties suggest a reduced environmental impact of newly formed group of herbicidal ionic liquids (HILs). HILs with a longer substituent can be characterized with better herbicidal activity in comparison with commercial products. (C) 2014 Elsevier Ltd. All rights reserved.

• Two step process for sweetening a sour hydrocarbon fraction

  公开（公告）日：1992-08-26

  This invention relates to a two step process for sweetening a sour hydrocarbon fraction containing tertiary mercaptans and primary or secondary mercaptans. In one step the mercaptans in the sour hydrocarbon fraction are reacted with hydrogen in the liquid phase and in the presence of a selective hydrogenolysis catalyst to selectively hydrogenolyse the tertiary mercaptans. In another step, the primary and/or secondary mercaptans are oxidized by reacting them with an oxidizing agent in the presence of oxidation catalyst and a basic component. The selective hydrogenolysis step and the oxidation step may be carried out in any order, i.e., either hydrogenolysis first followed by oxidation or vice versa.

  本发明涉及一种分两步对含有三硫醇和一硫醇或二硫醇的酸性烃馏分进行甜化的工艺。 在一个步骤中，酸性烃馏分中的硫醇在液相和选择性氢解催化剂存在下与氢反应，选择性地氢解叔硫醇。 在另一个步骤中，一级和/或二级硫醇在氧化催化剂和碱性成分的存在下与氧化剂发生反应而被氧化。 选择性氢解步骤和氧化步骤可以以任何顺序进行，即先氢解后氧化或反之。
