Abstract

Nitrophenyl alkyl ethers can be advantageously prepared by reacting a nitrophenol with an alkyl halide in water as the reaction medium in such a manner that the nitrophenol is laid before with the water and the alkyl halide and a hydrogen halide-binding compound are then added simultaneously.
