Abstract
PURPOSE: To prepare the titled compound useful as a slime controlling agent for paper-manufacturing industry, with low consumption of a brominating agent, in a short time, in high yield, by brominating m-nitroacetophenone in an aqueous medium.
CONSTITUTION: m-Nitroacetophenone is dispersed in an aqueous medium pref. as fine powder, and made to react with a brominating agent added thereto obtain m- nitro-ω-bromoacetophenone. The brominating agent is pref. bromine. Although water can be used as the aqueous medium, the addition of an acid or a salt to the medium accelerates the absorption of bromine and shortens the reaction time. The reaction temperature is pref. room temp.W100°C, esp. 60W90°C.
