ABSTRACT:
A process for preparing dibromonitro-alcohols, and mixtures thereof with bromonitro-alcohols, is disclosed in which dibromonitromethane, and optionally bromonitroethane, is reacted with a C.sub.1 -C.sub.3 aldehyde in aqueous solution at an acid pH, preferably between about 4.0 and about 7.0. An aqueous solution of the aldehyde is prepared and the pH adjusted to the desired acid range by addition of sodium bicarbonate, and the dibromonitromethane, which may include bromonitromethane, is added thereto. The dibromonitro-alcohol product is isolated as a separate phase from the reaction mixture.
