Method for the production of 1.6-hexanediol |
摘要 |
<p>Production of 1,6-hexanediol of purity at least 99.5 % comprises: (1) catalytically dimerizing a 1-8C acrylic acid ester in presence of rhodium compounds to a mixture mainly of 2- and 3-hexenedioic acid diesters; (2) hydrogenating the ester mixture in chromium-free mainly copper-containing catalysts; and (3) purifying the resulting diol mixture by fractional distillation.</p> |
