Title: Economical production of pure 1,6-hexane-diol from by-product of oxidation of cyclohexane
Inventor: BAUR KARL GERHARD DR
IPC: C07C29/149
Filed: 1996-03-01
Abstract: A process for the production of 1,6-hexanediol (I) from a carboxylic acid mixture (II) of adipic acid, 6-hydroxycaproic acid and small amounts of cyclohexan-1,4-diol(s) is obtained as by-product of the oxidation of cyclohexane to cyclohexanone/cyclohexanol with (gas containing) oxygen by extraction of the reaction mixture with water. The process involves esterification of the acids and hydrogenation. First, (a) the mono- and dicarboxylic acids in the aqueous (II) are esterified with a low molecular alcohol.  This is followed by 2 distillation stages, in which (b) excess alcohol and low-boiling compounds are removed and (c) the sump is separated into an ester fraction free from cyclohexan-1,4-diol(s) and a fraction of (mainly) cyclohexan-1,4-diol(s).  Then (d) the ester fraction is hydrogenated catalytically and (e) pure (I) is recovered from the hydrogenation product by distillation.
