Reaction Steps

34.6 g of tetraamylammonium cyanate (0.1 mole) and 250 ml of tetrahydrofurane are introduced into the reactor described in example 1. The solution is maintained saturated with CO2 at the atmospheric pressure. 8.4 g of hexamethylene diisocyanate (0.05 mole) are progressively added during 5 minutes. After 10 minutes of reaction, the solvent is evaporated and the obtained solid is washed with carbon tetrachloride. 44 g (yield: 94%) of tetraamylammonium bis-oxadiazinate of the following formula are obtained: ##STR17## this compound having a structure corresponding to that of formula (I).
