| 摘要 |
1 : 2-Dinitroethane is stabilised by the addition of an aromatic sulphonic acid such as benzene-, p - toluene-, or naphthalene - 2 - sulphonic acid, naphthalene-1 : 5-, naphthalene-2 : 7-, anthraquinone-1 : 5- or anthraquinone-1 : 8-disulphonic acid or mixtures of these. The stabiliser is incorporated in the 1 : 2-dinitroethane when molten either before or after a vacuum distillation, or the mixture of the stabiliser and 1 : 2-dinitroethane may be crystallised from a mutual solvent such as methyl and ethyl alcohols.
