MANUFACTURING METHOD OF LINEAR OR BRANCHED DIOL
-
Paragraph 0023; 0031, (2018/04/10)
PROBLEM TO BE SOLVED: To manufacture diol having 6 or more carbon atoms at a low cost. SOLUTION: There is provided a manufacturing method of long chain linear or branched diol, by a hydrogenation reaction of a compound having a carbon chain with 1 to 4 carbon atoms between a furan ring and an aldehyde group in presence of a solid catalyst to manufacture diol having 6 to 9 carbon atoms.

Studies on the Autoxidation of Nonbranched Aliphatic Monocarboxylic Acids and Their Methyl Esters

Valeric, caproic, and heptanoic acid and their methyl esters were oxidizied at 140 deg C by molecular oxygen.The oxidation mixtures were reduced by LiAlH4, and the mono- and dihydroxy compounds formed were analyzed gaschromatographically.From the results obtained one can conclude that nonbranched aliphatic acids and their methyl esters are attacked by the chain-carrying peroxy radicals at the different C-H bonds with almost the same regioselectivity as normal paraffins.Only the β- and to a smaller extent the α-positions are desactivated by the neighbouring carboxylic group.
