| titleOfInvention | Production of 4-nitrophenetole |
| abstract | PURPOSE: To obtain the subject compound without using purification process by reacting 4-chloronitrobenzene with ethanol in the presence of an alkali metal hydroxide using 1,3-dimethyl-2-imidazolidinone as a reaction solvent. n CONSTITUTION: 4-Chloronitrobenzene is made to react with ethanol in the presence of an alkali metal hydroxide using 1,3-dimethyl-2-imidazolidinone as a reaction solvent. The reaction is preferably carried out in the presence of an oxygen-containing gas at 30-100°C. 4-Nitrophenetole produced by the process can be used without purification such as recrystallization and is useful as a raw material for the production of 4-phenetidine by catalytic hydrogenation. The process is industrially advantageous and the product is extremely useful as an intermediate for dyes, agricultural chemicals and pharmaceuticals. n COPYRIGHT: (C)1991,JPO&Japio |
