Technical Report for the Period 1 January 1963 to 30 June 1963
Abstract
The four hydrazine perchlorates, viz. hydrazine perchlorate and its hemihydrate, and hydrazine diperchlorate and its dihydrate have been made in quantities of a few hundred grams from hydrazine and "Analar" grade sixty per cent perchloric acid. The monoperchlorate presents little difficulty; the extreme impact sensitiveness which has been reported (with F.I. worse than lead azide) has not been found even on material shown by the Karl Fischer test to be anhydrous. The dihydrate of hydrazine diperchlorate is also easy to obtain by mixing the cooled constituents. It is best dehydrated by low pressures (0.01 tor) at room temperature with a liquid nitrogen trap or phosphorus pentoxide to take up the water; it is not easy to avoid loss of some perchloric acid, and the analysis is often low in acid (the second perchloric acid titrates in aqueous solution as free acid). No solvent has been found for recrystallization of the anhydrous material; it hardly dissolves in liquid sulphur dioxide, and loses perchloric acid on washing with ether, tetrahydrofuran, and many others.
