Several of the dialkylamides of (trichlorophosphoranyli-dene)sulfamic acid are colorless oils which are obtained from the reaction mixture by evaporation of the solvent and purified by vacuum distillation. The latter is accompanied by some decomposition and a definite reduction in total yield. Caution. It is extremely important that air he kept out during the vacuum distillation. Otherwise, decomposition can he vigorous and extensive.) The chlorine atoms in all of these compounds are highly susceptible to solvolytic attack.
