PROCESS FOR PRODUCING HIGHLY PURIFIED N-PROPANOL

摘要

Disclosed is a process for the production of purified n-propanol having a content of n-propyl propionate of less than 0.003 wt.-% as well as the use of the purified n-propanol thus obtainable for the manufacture of medicaments. The process comprises the steps: a) feeding crue n-propanol to a distillation column, b) separately feeding water to said distillation column, c) separating an azeotropic mixture which comprises at least water, n-propanol and organic impurities at the top of the distillation column and d) isolating the purified n-propanol from the bottom of the distillation column.
