| abstract |
PROCESS FOR THE PURIFYING DISTILLATION OF CRUDE SEC-BUTYL ALCOHOL (D#71,200 - DTA-189-F) ABSTRACT OF THE INVENTION Practically anhydrous crude sec-butyl alcohol produced by catalytic direct hydration of n-butenes is freed by means of water from th azeotropically boiling and low-boiling by-products by continuous azeotropic distillation in a separation column, the prepurified anhydrous sec-butyl alcohol obtained is withdrawn and the high-boiling by-products are subsequently separated in a separate column. pr43 |
