    摘要: The invention relates to a method for the safe production of nitroethionate, by reaction of 4-nitro-N-methylaniline with 1,3-dioxa-2,4-dithian-2,4-bis dioxide. The method is characterised in that an ether of polyhydric alcohols or a cyclic ether in a nitrile substituted hydrocarbon is chosen as solvent. The risk of localised overconcentration, localised overheating or explosions is avoided by a homogeneous reaction procedure.
