Abstract
In the production of hydroxylammonium salts by the action of a mineral acid on a primary nitroalkane, the nitroalkane is slowly added to a mixture of at least 0.8 moles. of mineral acid per mole. of nitroalkane and at least 0.8 moles. of water per mole. of nitroalkane. During the mixing the temperature is preferably maintained between 90 DEG C. and 150 DEG C., and after the mixing has been completed between 120 DEG C. and 160 DEG C. The preferred nitroalkane is 1-nitropropane and the preferred mineral acid is sulphuric acid. Nitroethane and nitrobutane are also specified. Carboxylic acids are also formed, propionic acid being obtained when 1-nitropropane is employed. In an example, hydroxylammonium acid sulphate, produced by the action of sulphuric acid on 1-nitropropane, was converted to the chloride by adding the sulphate to a solution of methanol in hydrochloric acid, and filtering off the chloride produced.ALSO:Carboxylic acids are obtained in the production of hydroxylammonium salts by adding a primary nitroalkane to a mixture of at least 0.8 moles. of mineral acid and 0.8 moles. of water per mole. of nitroalkane, and preferably maintaining the temperature at 90-160 DEG C. during the addition and at 120-160 DEG C. after addition. The preferred mineral acid is sulphuric acid. The preferred nitroalkane is 1-nitropropane, which give propionic acid. Nitroethane and nitrobutane are also referred to.
