<p>PURPOSE:To easily dissolve many metals by bringing metals into contact with an organic solvent in the presence of quaternary ammonium trihalide obtd. by the reaction between a cationic surface active agent and halogen simple substance. CONSTITUTION:A cationic surface active agent and halogen simple substance expressed by a general formula [RidenticalN-R']<+>.X<-> (in the formula, RidenticalN denotes trialkylamino groups or pyridyl groups, R' denotes 6 to 22 C alkyl groups and X denotes halogen atoms) are dissolved in liquid hydrocarbon, and they are brought into reaction. By bringing metals into contact with the formed quaternary ammonium trihalide shown by a general formula [RidenticalN-R']<+>.X (in the formula, RidenticalN denotes trialkylamino groups or pyridyl groups, R' denotes 6 to 22 C alkyl groups and X denotes halogen atoms) and an organic solvent, the metals are converted into compounds easy to dissolve and are easily dissolved.</p> |
