Abstract: : CONTINUOUS PROCESS FOR THE PRODUCTION OF PEROXYCARBOXYLIC ACID COMPOSITIONS Peroxycarboxylic acid compositions containing stabilizing ingredients are produced by the hydrogen peroxide peroxidation of corresponding carboxylic acids which are not substantially soluble in water by a continuous process in which the peroxidation reaction takes place in solution in concentrated sulfuric acid, or other strong acid, while that solution is intimately interdispersed, by means of agitation, with methylene chloride, or other organic solvent, in which the resulting peroxycarboxylic acid is soluble, but the carboxylic acid is not, and the sulfuric acid, or other acid, is recovered from the effluent of the process by reacting it with borax and caustic soda or soda ash to form crystals of boric acid and sodium salt of the strong acid which, in admixture with peroxycarboxylic acid recovered from the effluent, form the peroxycarboxylic acid composition product. The methylene chloride is also recovered from the effluent and recycled to the process.

Abstract: A novel process, the products produced and their use in rendering rayon flame retardant. The process comprises treating partial esters of phosphonitrilic chloride with a tertiary amine base to form a polymeric phosphazene. The condensed polymeric phosphazenes so produced are very efficacious in rendering rayon flame resistant and they have excellent retention during the process of spinning rayon fibers and in subsequent laundering of fabrics produced from the flame-resistant rayon.

Abstract: 1390306 Preparing polymeric phosphazenes FMC CORP 16 Aug 1973 [17 Aug 1972] 38713/73 Heading C2P [Also in Division C3] A polymeric phosphazene is obtained by reacting a phosphonitrilic chloride polymer with a metallic alkoxide or an alkanol in the presence of an acid acceptor, the alkyl portion of the alkoxide or alkanol containing 1 to 12 carbon atoms, to produce a chlorine-containing phosphazene ester containing 1 to 15% unreacted chlorine by weight and heating the chloroester at 100‹ to 250‹ C. to form a condensed polymeric phosphazene ester of increased molecular weight. The starting polymer may be a linear or cyclic polymer but is preferably a mixture of linear and cyclic polymers. The condensation step which may be carried out in the presence of a catalyst, e.g. copper, involves elimination of alkyl halide and the final product may contain residual chloride. The products are useful as flame retardants for regenerated cellulose.
