| titleOfInvention | Improvements in or relating to the preparation of nitro derivatives |
| abstract | A process for the preparation of a nitro derivative of an alkane, cycloalkane or aryl-substituted alkane comprises admixing an alkyl nitrite or cycloalkyl nitrite with a molar excess of an alkane, cycloalkane or aryl-substituted alkane in a reaction zone maintained at a temperature within the range of 140 DEG and 300 DEG C., said hydrocarbon being maintained substantially in the liquid phase by the application of pressure. The terms "alkyl nitrite" and cycloalkyl nitrite are used to denote alkane and cyclo-alkane hydrocarbons in which at least one hydrogen atom has been replaced by a nitrite group. In a modification of the process the alkane, cycloalkane or aryl-substituted alkane contains a non-hydrocarbon substituent inert under the reaction conditions employed. Nitrites specified include cyclohexyl, n-butyl, tert-butyl, ethyl, n-propyl, isopropyl and hexyl nitrite, mixed amyl nitrite and 1,4-butylene dinitrite. Starting materials mentioned include n-nonane, n-decane, 2,3-dimethylbutane, n-hexane, neohexane, isooctane, methylcyclohexane, cycloheptane, cyclopentane, alkylated cycloheptanes and cyclopentanes, ethyl benzene, toluene, p-xylene, cumene, cymene, durene and diisopropyl - benzene. Non - hydrocarbon substituents which may be present in the starting materials include nitro and halo groups, e.g. as in nitrocyclohexane, chlorocyclohexane, chlorodecane and bromopentane. Diluents mentioned include benzene and acetonitrile. The process may be operated continuously. Examples relate to the production of nitrocyclohexane by nitrating cyclohexane with n-butyl nitrite (I)-(IV), to the nitration with n-butyl nitrite of n-nonane, n-decane, ethylbenzene, toluene, chlorocyclohexane, p-xylene, methylcyclohexane, p 2,2-dimethylbutane, cumene and cyclohexane (IV) and to the nitration of cyclohexane with cyclohexyl, isobutyl and tert.-butyl nitrite (V). |
