Peroxycarboxylic acids are prepared by the oxidation of a fatty acid with an excess of hydrogen peroxide in the presence of a strong acid catalyst. The yield is improved and the reaction time is reduced by intimately dispersing throughout the reaction mixture an inert water immiscible solvent for the peroxycarboxylic acid. The product may be recovered in crystalline form from the solvent phase.

Novel sulfate salts of C. sub. 10 -C. sub. 20 linear alkyl glyceryl ether alcohols, useful as biodegradable surfactants in detergent compositions, are prepared by reacting a stoichiometric excess of C. sub. 10 -C. sub. 20 linear alkyl alcohol with glycidol predissolved in hexyl acetate, to selectively produce C. sub. 10 -C. sub. 20 linear alkyl glyceryl ether alcohols containing 1-3 glyceryl units, sulfating said ether alcohols, and neutralizing the sulfates with base.

Salts of dihalogenated isocyanurates are prepared by reacting amino substituted triazines with at least stoichiometric amounts of a halogen containing compound at a temperature of 35. degree. to 70. degree. C. and at a pH value of 6. 5 to 11. 0 until all of the available sites on the triazine molecule are N-halogenated and N, N-dihalogenated exocyclic nitrogen is removed.

Process for purifying crude cyanuric acid whereby crude cyanuric acid is digested with a mono-substituted salt of a dibasic or tribasic inorganic acid at a temperature of about 160. degree. C to about 220. degree. C under at least the autogenously developed pressure to digest the crude cyanuric acid. A novel, large, free-flowing cyanuric acid product is recovered free of any hard cement-like masses.

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.
