PROCESS FOR PRODUCTION OF PURIFIED ALCOHOLS |
摘要 |
<p>A process for producing purified alcohols yielding good results in the acid wash color test which comprises the condensation step of subjecting an aldehyde to aldol condensation and dehydration to obtain a corresponding condensate, the hydrogenation step of hydrogenating the condensate into a crude alcohol, and the purification step of distilling the crude alcohol to obtain a purified alcohol, characterized by feeding into the purification step a crude alcohol containing compounds having oxygenic heterocycles bearing carbon-carbon double bonds in the cycle in a concentration of as low as 200 ppm by weight or below. In particular, the aldehyde is n-butyraldehyde, the condensate is 2-ethylhexenal, and the alcohol is 2-ethylhexanol.</p> |
