  • Process for preparing divinyl ethers
    Patent number: 8946487
    Abstract: Process for preparing divinyl ethers by reacting compounds having two hydroxyl groups (hereinafter referred to as diols) with acetylene, wherein the hydroxyl groups are incompletely reacted with acetylene and the resulting product mixture therefore comprises the monovinyl ether in addition to the divinyl ether and the monovinyl ether is separated off from the product mixture by extractive distillation in the presence of an extractant.
    Type: Grant
    Filed: February 16, 2012
    Date of Patent: February 3, 2015
    Assignee: BASF SE
    Inventors: Thomas Maidhof, Helmut Kronemayer, Georg Heinrich Grosch, Regina Vogelsang, Klaus Peter Gumbel, Tim Balensiefer, Alexey Shilkin
  • Enzymatic hydrolysis of a cellulose material treated with an ionic liquid
    Patent number: 8486669
    Abstract: A process for preparing glucose from a cellulose material, in which a cellulose-comprising starting material is provided and treated with a liquid treatment medium comprising an ionic liquid whose anions are selected from among polyatomic anions and the cellulose-comprising material which has been treated with the ionic liquid is subjected to an enzymatic hydrolysis, is described.

  • PROCESS FOR THE PREPARATION OF MONOETHYLENICALLY UNSATURATED GLYCOSYLAMINES
    Publication number: 20120016114
    Abstract: The present invention relates to a process for the preparation of monoethylenically unsaturated glycosylamines, in which an aldehyde sugar is reacted with a primary aliphatic amine or ammonia in aqueous medium and, without interim isolation, is reacted with the anhydride of a monounsaturated carboxylic acid, or an aldehyde sugar is reacted directly with allylamine, and to a process for the preparation of polymers which comprise N-acylated glycosylamine groups in copolymerized form, and to novel unsaturated N-maleinylated glycosylamines.
