PROCESS FOR THE CONTINUOUS PURIFYING DISTILLATION OF CRUDE SEC-BUTYL ALCOHOL OBTAINED BY CATALYTIC HYDRATION OF AT LEAST ONE N-BUTENE |
摘要 |
<p>Crude, virtually anhydrous sec-butyl alcohol, prepared by catalytic direct hydration of n-butenes is freed from the by-products which can be distilled azeotropically and are highly volatile by continuous azeotropic distillation in a separation column by means of water, the pre-purified sec-butyl alcohol which is obtained in anhydrous form is removed and the high-boiling by-products are then separated off in a separate column. …<IMAGE>… </p> |
