  Halogen-free ionic liquids and their utilization as cellulose solvents

  摘要：

  This work demonstrates a novel synthesis route to halogen-free ionic liquids. A one-pot synthetic reaction route avoiding the use of toxic and high-energetic alkyl halides was developed to reduce the environmental impact of the synthesis process of ionic liquids. However, the elimination of halogens and alkyl halides in the preparation of ionic liquids is not just an environmental issue: the aforementioned species are also among the most common and persistent contaminants in today's Ionic Liquids (ILs). Thus, this paper introduces a range of quaternized nitrogen based ionic liquids, including both aromatic and non-aromatic components, all prepared without alkyl halides in any step of the process. Moreover, bio-renewable precursors such as (bio-)alcohols and carboxylic acids were employed as anion sources and alkylation media, thus avoiding halogen contamination or halogen-containing anions. The IL's prepared were designed to dissolve cellulose, some of which was included in a cellulose dissolution study using a sulphite cellulose from the company Domsjo. (C) 2012 Elsevier B.V.

  A quaternary ammonium hydroxycarboxylate is produced by quaternizing a tertiary amine with a hydroxycarboxylic ester represented by the following Formula 1: 1 wherein R 1 to R 3 are as defined in the disclosure. By using only one tertiary amine having at least one substituent different from R 1 of the ester moiety of the hydroxycarboxylic ester and by controlling the reaction conditions, a mixture of quaternary ammonium hydroxycarboxylates having different quaternary ammonium ions is produced. By reacting an inorganic acid with the quaternary ammonium hydroxycarboxylate or its mixture, a quaternary ammonium salt of inorganic acid or its mixture is produced.
