Method for the production of 1,6-hexanediol |
| abstract |
The invention relates to a method for producing 1,6-hexanediol having a purity of > 99.5 wt. % by catalytic dimerisation of acrylic acid esters, catalytic hydrogenation of the thus obtained hexene diacidic diester in order to form 1.6-hexanediol. Said method consists in: a) dimerising C1- C8-acrylic acid esters in the presence of at least one rhodium compound in order to form mixtures predominantly of 2- and 3-hexene diacdic diesters, b) hydrating the obtained dimerisation discharge in the presence of chrome-free catalysts containing mainly copper as a hydrogenation component and c) purifying the thus obtained raw 1.6-hexanediol by fractionating distillation. |
