On August 1, 2020, Toyooka, Genki; Fujita, Ken-ichi published an article.Quality Control of Pentane-1,5-diol The title of the article was Synthesis of Dicarboxylic Acids from Aqueous Solutions of Diols with Hydrogen Evolution Catalyzed by an Iridium Complex. And the article contained the following:
A catalytic system for the synthesis of dicarboxylic acids e.g., glutaric acid from aqueous solutions of diols e.g., pentane-1,5-diol accompanied by the evolution of hydrogen was developed. An iridium complex bearing a functional bipyridonate ligand with N,N-dimethylamino substituents exhibited a high catalytic performance for this type of dehydrogenative reaction. For example, adipic acid was synthesized from an aqueous solution of 1,6-hexanediol in 97% yield accompanied by the evolution of four equivalent of hydrogen by the present catalytic system. It should be noted that the simultaneous production of industrially important dicarboxylic acids and hydrogen, which is useful as an energy carrier, was achieved. In addition, the selective dehydrogenative oxidation of vicinal diols CH3(CH2)nCH(OH)CH2OH (n = 0, 1, 2, 3) to give α-hydroxycarboxylic acids CH3(CH2)nCH(OH)COOH was also accomplished. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Quality Control of Pentane-1,5-diol
