ABSTRACT:
Compounds containing a chloroammelide moiety having the formula ##STR1## wherein R is alkali metal or H, Y is Cl or H, and Y is H when R is H, said compounds being not fully hydrated when R is alkali metal, contain both free and combined chlorine, and are attractive for use in bleaching. Those not fully hydrated can be prepared by removing combined water of hydration from more fully hydrated compounds obtained by chlorinating an aqueous mixture of ammelide and alkali metal ions. The fully hydrated compound wherein R is H is prepared by chlorinating an aqueous mixture of ammelide and about 2-2.2 moles of alkali metal ion per mole of ammelide.
