摘要: A method of preparing a monohalogenated nitroalkane which comprises reacting equal molar quantities of an alkali metal hydroxide and a nitroalkane in a suitable medium to form a nitronate salt therein, promptly mixing the medium containing the nitronate salt with an equal molar quantity of a halogen to form a monohalogenated nitroalkane in the medium, promptly adding a material to the medium containing the monohalogenated nitroalkane to terminate any further halogenation therein, and recovering the monohalogenated nitroalkane from the medium.

摘要: A method of preparing an amino alcohol of the formula ##STR1## where R.sub.1 is H, lower alkyl or R.sub.2, R.sub.2 is R.sub.3 CHOH in which R.sub.3 is H, alkyl or aryl. R.sub.3 preferably is hydrogen, lower alkyl or monocyclic aryl such as phenyl. The inventive method involves the reaction of halonitroalcohol with hydrogen in the presence of methanol, a suitable buffering agent such as ammonia, and a hydrogenation catalyst to form amino alcohol salt, neutralizing the amino alcohol salt, and recovering the resultant amino alcohol.
