IPC: D01F2/28
Filed: 1936-05-22
Abstract: Continuous artificial filaments, artificial yarns, foils, and the like of organic derivatives of cellulose are subjected to the action of hot water or wet steam under pressure at a temperature above 100 DEG  C., in the absence of tension sufficient to stretch them.  The extensibility of the materials is thereby improved. The hot water or wet steam employed may contain low concentrations of swelling agents, e.g. acetone, methylene ethylene ether or dioxane.  Temperatures of 110 DEG , 120 DEG , and 140 DEG  C. are specified, and steam when employed, is of high degree of wetness, e.g. 5 to 10 per cent.  The process is particularly applicable to materials which have been stretched, for example up to 100, 150, or 180 per cent of their original length, and suitable stretching processes are those described in Specifications 438,584 and 438,656, wherein stretching takes place in the presence of saturated or wet steam. The shrinking operation may be carried out on the materials in package form, or whilst they are travelling, and for the latter purpose, the apparatus of Specifications 438,584, 443,707, and 443,773 may be employed.

Title: Process for the purification of triaryl phosphates
Inventor: REEVES GEORGE
IPC: C07F9/12
Filed: 1958-05-09
Abstract: Phenolic impurities are removed from a crude triaryl phosphate by suspending the latter in water, adding an aqueous solution of a diazotised sulphonated aryl amine to the suspension in an amount in excess of that required to react with the phenolic impurity, sufficient alkali having been incorporated in the suspension to ensure that the final mixture is alkaline, so that the phenolic impurity is converted into a sulphonated azo dye which dissolves in the aqueous phase and separating the triaryl phosphate from the aqueous phase.  The reaction between the phenolic impurity and the diazotised aryl amine is preferably effected at a temperature between 55 DEG C. and 65 DEG C.  The process is particularly applicable to the purification of triaryl phosphates, e.g. triphenyl or tricresyl phosphate, obtained by reacting phosphorus oxychloride and a phenol in the presence of anhydrous magnesium chloride as catalyst and an example is given for the purification of triphenyl phosphate obtained in this way and using p-sulphanilic acid as the sulphonated aryl amine.
