| titleOfInvention | Production of n-vinylformamide |
| abstract | PURPOSE: To obtain the titled compound in high yield, by etherifying N-(α- hydroxyethyl)formamide with a polyhydric alcohol, heating the ether compound under reduced pressure in a liquid phase and carrying out thermal decomposition while distilling away N-vinylformamide. n CONSTITUTION: N-(α-Hydroxyethyl)formamide is etherified with a polyhydric alcohol such as dihydric alcohol, etc., in the presence of a catalyst of a mineral acid such as sulfuric acid, etc., at 0W100°C for 0.5W5hr, heated in a liquid phase at ≤200Hg reduced pressure at 90W200°C and thermal decomposition is carried out while distilling away formed N-vinylformamide, to give the aimed compound. n EFFECT: A small amount of by-products such as resin component, etc., is formed, the temperature of the thermal decomposition is lower than a conventional gaseous-phase method so this process is advantageous with respect to heat energy. There is not such problem in operation as clogging of a reaction tube with resin like a gaseous-phase method and this process is an industrially improved method. n USE: A polymerizable monomer to provide a water-soluble polymer as a flocculant. n COPYRIGHT: (C)1987,JPO&Japio |
