Then in another tower, of which the height was 1.6m and the inner diameter was 20mm, the pentanol mixture was exactly rectified. The influence factors on separation effect, for example, the material concentration, evaporation velocity, circumfluence rate.etc, were studied and a set of separation system about salt-out -exactitude rectify was upbuilt. The result showed: when the material concentration was 60%, we got our product, 2-methyl-1-butanol, with the concentration over 99% and the top quality recovery over 82.7% which would increase as the material concentration did.
