Chloroisocyanurate compounds

Abstract

Novel hydrated, potassium-containing chloroisocyanurate complex compounds and mixtures thereof are described together with processes for preparing the same. The novel compounds of this invention, namely, [(mono-trichloro,) tetra-(monopotassium dichloro,)] penta-isocyanurate tetrahydrate, and hydrated (mono-trichloro,) (monopotassium dichloro,) di-isocyanurate and mixtures thereof, are prepared by reacting in a substantially dry state trichloroisocyanuric acid and potassium dichloroisocyanurate monohydrate, the reaction products being determined by the molecular ratio of the starting materials. These novel compounds are resistant to burning, will not undergo self-propagating decomposition when subjected to a source of intense heat, as for example a hot wire, and are useful as a source of available chlorine in, for example bleaching, sterilizing, oxidizing and disinfecting operations. Further, the novel compounds of this invention and mixtures thereof can be dehydrated to produce the corresponding non-hydrated compounds, namely [(mono-trichloro,) tetra-(monopotassium dichloro,)] penta-isocyanurate and (mono-trichloro,) (monopotassium dichloro,) di-isocyanurate and mixtures thereof, which non-hydrated compounds and mixtures thereof are known in the art and are useful as a source of available chlorine.
