标 题 :Synthesis of alkoxy and phenoxy substituted aryl sulfides
发明人：HANSON HARRY T; SAPP JR JOHN B
权利人:CELANESE CORP
摘要:Provided is a novel process for the synthesis of aryl sulfides substituted with an alkoxy or phenoxy substituent. The process comprises reacting an alkoxy or phenoxy substituted aromatic compound with a sulfur dihalide, preferably sulfur dichloride, in the presence of an alkali metal tetrafluoroborate catalyst, with the amount of said aromatic reactant compound preferably being sufficient to solvate the sulfur dichloride and catalyst sufficiently to allow the reaction to occur.

摘要:A synthesis method of cathode material for lithium battery is provided. The method includes dissolving lithium, nickel and cobalt acetate in a solution, adding ammonium dihydrogen phosphate to the solution, adding acid to the solution, heating the solution to a first temperature for a first period of time to form a solid mixer material, and sintering the solid mixer material at a second temperature for a second period of time.

标题 :Process for the preparation of carbinols

摘要:Organic compounds containing a carboxylic acid or carboxylic acid anhydride group are reduced when contacted with an alkali metal borohydride and a boron trihalide in a liquid medium in which diborane is soluble in the form of a labile borane adduct. Hydrolysis of the reaction mixture then provides a useful synthesis of the corresponding carbinols. n The alkali metal borohydride-boron trihalide reagent may either be preformed and reacted subsequently with an organic compound containing a carboxylic acid or anhydride group, or the alkali metal borohydride-boron trihalide reagent may be produced in the presence of an organic compound containing a carboxylic acid or anhydride group. This development makes it possible to synthesize a wide variety of carbinols which are valuable and useful intermediates in organic synthesis.

标题:Synthesis of carbon/silicon composites
发明人：GROSS KARL J; WANG JAMES C F; ROBERTS GREGORY A
摘要:The present embodiment relates to a method for preparing a composite graphite-silicon negative electrode material whereby an essentially dry mixture of graphite carbon powder and an element or elements selected from the new IUPAC Group Number 12-15 of the Periodic Table of Elements that can form alloys or compounds with lithium is prepared to provide an electrochemically active mixture. A mechanical agitation process serves to mix the constituent materials and to produce a fine dispersion with intimate contact between graphite and the Group 12-15 materials. A lithium ion battery negative electrode of this composition takes synergistic advantage of the high lithium capacity of some IUPAC Group materials and the long cycle-life of graphite negative electrode materials.
