摘要

"Su00ecntese 1,3 - aliphatic diols using low concentration of ligand and extraction with water.A process for synthesizing 1,3 diols, aliphatic in single step by hidroformilau00e7u00e3o and hydrogenation of oxirana, carbon monoxide and hydrogen.By employing a catalyst comprising a cobalt carbonyl compound and a compound of metal co catalyst bound with a binder.In a molar ratio of ligand to metal atom cocatalisador in the range of 0.2: 1,0 0,6 1,0, optionally in the presence of a promoter.In the recovery of the product is preferably carried out by extraction with water of a phase rich in diol from the reactional mixture in the bulk.The changes in the process may be beneficial, particularly in combination, with reference to the recovery of the product.Recycling of the catalyst and the economic viability of a general process in one step for the production of 1,3 - aliphatic diols.
