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.摘要翻译: 一种由通式表示的二溴硝基化合物的制备方法,其中R表示氢原子或甲基,该方法包括在碱的存在下将硝基甲烷与甲醛或乙醛缩合,醛的量为每摩尔至少1.5摩尔 硝基甲烷; 然后不分离产物,用溴处理反应混合物以溴化产物。
