Title:
PRODUCTION METHOD FOR N–(α–HYDROXYETHYL) FORMAMIDE, PRODUCTION METHOD FOR N–(α–ALKOXYETHYL) FORMAMIDE, PRODUCTION DEVICE FOR N–(α–HYDROXYETHYL) FORMAMIDE, AND PRODUCTION DEVICE FOR N–(α–ALKOXYETHYL) FORMAMIDE
Document Type and Number:
WIPO Patent Application WO/2018/105720
Kind Code:
A1
Abstract:
Provided is a production method for N–(α–hydroxyethyl) formamide, having a step (1) in which a basic catalyst stored in a catalyst supply device and formamide are mixed in a mixing tank; and a step (2) in which the formamide mixed with the basic catalyst is brought in contact with acetaldehyde and N–(α–hydroxyethyl) formamide is obtained. In step (1), at least part of the catalyst supply device is vibrated while the basic catalyst is supplied to the mixing tank.
