る。When adding aqueous ammonia, a method can be adopted in which an amount obtained by adding the above-mentioned equivalent amount required for the reaction and the amount lost by evaporation, for example, 5 times the equivalent amount, is used. Can be achieved. Alternatively, it is also possible to use a method in which only the minimum necessary amount is initially charged and replenish the evaporation during heating, or a method in which a necessary amount of aqueous ammonia is charged into a pressure-resistant closed vessel such as a pressure cooker to cause a reaction. Good. According to these methods, the amount of ammonia water used can be reduced. In particular, in the case of a method using a closed container, almost no ammonia is released, so that the cost of the exhaust treatment can be reduced. By maintaining ammonia alkalinity during heating, the dichlorodiammine platinum (II) crystal is completely replaced by tetraammineplatinum (II) dichloride.

If it is less than 70 ° C., the reaction proceeds slowly, and the reaction rate is more preferably 70 ° C. or more. On the other hand, if the temperature exceeds 80 ° C., the solubility of ammonia decreases, which is not preferable. The form of the reaction differs depending on the heating temperature.
Since the crystal does not dissolve, it takes the form of a so-called solid-liquid reaction that changes directly from dichlorodiammineplatinum (II) crystal to tetraammineplatinum (II) dichloride crystal. Therefore, at the end of the reaction, the whole solution becomes a homogeneous solution.
In an intermediate heating temperature range, for example, 75 ° C., the above-mentioned state is mixed.
