摘要

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.
