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.
Claims17
A method for producing N-(α-hydroxyethyl)formamide, comprising:
- a step (1) of mixing a basic catalyst stored in a catalyst supply facility with formamide in a mixing tank;
- a step (2) of bringing the formamide mixed with the basic catalyst into contact with acetaldehyde and obtaining N-(α-hydroxyethyl)formamide;
- wherein
- the basic catalyst is supplied to the mixing tank while vibrating at least a part of the catalyst supply facility in the step (1).
A device for producing N-(α-hydroxyethyl)formamide, comprising:
- a catalyst supply facility for storing a basic catalyst;
- a mixing tank for mixing the basic catalyst supplied from the catalyst supply facility with formamide;
- a third tank for bringing the formamide which is mixed with the basic catalyst and supplied from the mixing tank into contact with acetaldehyde and obtaining N-(α-hydroxyethyl)formamide;
- and
- a vibration imparting means for vibrating at least a part of the catalyst supply facility.
A device for producing N-(α-alkoxyethyl)formamide, comprising:
- a catalyst supply facility for storing a basic catalyst;
- a mixing tank for mixing the basic catalyst supplied from the catalyst supply facility with formamide;
- a third tank for bringing the formamide which is mixed with the basic catalyst and supplied from the mixing tank into contact with acetaldehyde and obtaining N-(α-hydroxyethyl)formamide;
- a fourth tank for bringing the N-(α-hydroxyethyl)formamide supplied from the third tank into contact with an alcohol in presence of an acid catalyst and forming N-(α-alkoxyethyl)formamide;
- and
- a vibration imparting means for vibrating at least a part of the catalyst supply facility.
