METHOD FOR PREPARING 5-HYDRAZINOTETRAZOLE-MERCURY (II) PERCHLORATE Russian patent published in 2004 - IPC

FIELD: inorganic chemistry, chemical technology. SUBSTANCE: invention relates, in particular, to methods for preparing mercury (II) compounds used as initiating explosive substance, in film charges for devices generating flat impact waves and others. Invention provides preparing 5-hydrazinotetrazole-mercury (II) perchlorate with the yield of the end product 50%, not less. Method for preparing involves mixing mercury (II) compounds as mercury (II) salt or mercury (II) oxide with 5-hydrazonotetrazole or its salt in 5-70% perchloric acid solution at temperature 10-70 C in the mole ratio 5-hydrazinotetrazole or its salt : mercury (II) compound = (0.8-2.0):1. Precipitate of 5-hydrazinotetrazole- mercury (II) perchlorate is filtered off, washed with water and alcohol and dried. Mercury (II) perchlorate is used as a mercury (II) salt. EFFECT: improved preparing method. 2 cl, 3 ex
