ABSTRACT:
Purified isopropanol is obtained from a crude reaction mixture by removing high boiling oils with activated carbon, extraction with a high boiling solvent and distillation with energy saving use of distillation vapors to heat successive distillation steps. Recyle of components also improves the overall economics of the process.
