摘要：
A process for producing a dibromonitro compound represented by the general formula
wherein R represents a hydrogen atom or a methyl group, which comprises condensing nitromethane with formaldehyde or acetaldehyde in the presence of an alkali, the amount of the aldehyde being at least 1.5 moles per mole of nitromethane; and thereafter without isolating the product, treating the reaction mixture with bromine to brominate the product.
