PROCESS FOR PREPARING 4-NITROPHENETOLE

4-Nitrophenetol is prepared by reaction of 4-chloronitrobenzene with ethanol and alkali metal hydroxides in the presence of phase-transfer catalysts by carrying out the reaction at temperatures from 60 DEG to 95 DEG C. and under pressure in the presence of oxygen-containing gases diluted with inert...

Zusammenfassung:4-Nitrophenetol is prepared by reaction of 4-chloronitrobenzene with ethanol and alkali metal hydroxides in the presence of phase-transfer catalysts by carrying out the reaction at temperatures from 60 DEG to 95 DEG C. and under pressure in the presence of oxygen-containing gases diluted with inert gases, there being at the start of the reaction 0.2 to 1.0 mol of alkali metal hydroxide metered each hour into the reaction mixture for each 1 mol of 4-chloronitrobenzene.
