    摘要： Soluble methylol phosphine adducts which contain one or more methylol phosphine radicals (PCH2OH) are prepared by reacting in a suitable solvent tris(hydroxymethyl)phosphine with an amide or amine which contains one or more hydrogens attached to trivalent nitrogen. These soluble adducts are particularly valuable for the preparation of thermosetting flame resistant polymers by reacting them with nitrogenous compounds which contain two or more hydrogen and methylol groups attached to trivalent nitrogen. The adducts are also valuable for the preparation of flame-, glow-, wrinkle-, and shrink-resistant knit and woven textiles by causing the adducts to react with nitrogenous compounds in or on the textile structure by application of heat.

    摘要： An improved chainless mercerizer utilizing a series of graduated rollers which increase the efficiency of a chainless mercerizer. Each driven roller is constructed incrementally larger in diameter than the previous driven roller in the direction of fabric travel through the mercerizer. The fabric being mercerized is stretched incrementally tighter as it is transferred from one driven roller to the next succeeding one, thereby increasing the forces opposing widthwise shrinkage. The idler rollers have a uniform diameter approximately that of any of the driven rollers.

    摘要： 1. A PROCESS FOR PREPARING PHOSPHINIDYNETRIMETHANOL TRIACETATE, WHICH PROCESS COMPRISES; (A) REACTING ACETIC ANHYDRIDE AND TETRAKIS(HYDROXYMETHYL)PHOSPHONIUM CHLORIDE IN PYRIDINE AT ROOM TEMPERATURE BY DISSOLVING 303 GRAMS (1.59 MOLES) OF SAID TETRAKIS(hYDROXYMETHYL)PHOOSPONIUM CHLORIDE IN 1800 MILLILITERS OF PYRIDINE AT ROOM TEMPERATURE, AND SLOWLY ADDING ABOUT 727 GRAMS (7.13 MOLES) OF ACETIC ANHYDRIDE WHILE STIRRING THE REACTION MIXTURE, TO MAINTAIN A TEMPERATURE OF THE MIXTURE AT BELOW 40*C; (B) CONTINUING THE REACTION UNTIL ALL OF THE TETRAKIS(HYDROXYMETHYL)PHOSPHONIUM CHLORIDE IS CONSUMED, THE SAID ACETIC ANHYDRIDE BEING PRESENT IN EXCESS; (C) REMOVING THE PYRIDINE BY DISTILLATION UNDER VACCUM TO OBTAIN AN OILY RESIDUE; (D) WASHING THE OILY DISTILLATION RESIDUE WITH WATER TO REMOVE UNREACTED STARTING MATERIALS AND UNDESIRED WATER-SOLUBLE PRODUCTS THEREBY OBTAINING A BROWN OIL WHICH SEPARATES; (D) DRYING THE SEPRATED BROWN OIL WITH ANHYDROUS SODIUM SULFATE OR SUITABLE SUBSTITUTE DRYING AGENT THEREFOR; AND (F) DISTILLING THE PRODUCT FROM (E) UNDER VACUUM TO OBTAIN PHOSPHINIDYNETRIMETHANOL TRIACETATE, A COLORLESS PRODUCT.

    摘要： IMPROVED CATALYST SYSTEMS HAVE BEEN FOUND THAT CAN BE USED IN PLACE OF THE CATALYST SYSTEMS PREVIOUSLY REQUIRED TO CURE FLAME-RETARDANT FINISHES FOR CELLULOSE TEXTILES. THESE IMPROVED CATALYST SYSTEMS CONSIST OF A MIXTURE OF ALUMINUM CHLORHYDROXIDE AND AN ACID SELECTED FROM THE GROUP PHOSPHORIC ACID, AXALIC ACID, LACTIC ACID OR A MIXTURE SELECTED FROM THE GOLLOWING: ZINC CHLORIDEGLYCOLIC ACID, MAGNESIUM CHLORIDE-CITRIC ACID, AND MAGNESIUM CHLORIDE-GLYCOLIC ACID. UNLIKE CELLULOSIC FABRICS TREATED WITH THE THP-AMIDE OR THPOH-AMIDE FINISHES WITH OR WITHOUT OTHER CATALYST SYSTEMS, FABRICS SIMILARLY PROCESSED WITH THE IMPROVED CATALYST SYSTEM, THAT IS, THE ONES CONTAINING ALUMINUM CHLORHYDROXIDE HAVE LOWER STIFFNESS VALUE AND A MUCH BETTER HAND.
