| 摘要 |
Quaternary ammonium nitrates having a low chloride content are prepared by reacting a quaternary ammonium chloride with ammonium nitrate, potassium nitrate or sodium nitrate at an initial temperature of above about 50 DEG C., in a substantially non-aqueous solvent comprising dimethyl formamide or a saturated monohydric alcohol having from one to four carbon atoms, the products being a quaternary ammonium nitrate and an insoluble chloride salt, Numerous suitable starting materials are specified, the organic radicals being unsubstituted or substituted by group such as amide or ether groups, the quaternary nitrogen atom being in some cases a member of a heterocyclic ring. Examples are given.
