Abstract: There is described the preparation of a flameproofing compound useful in the production of cellulosic fibres having a high resistance to combustion, said preparation comprising treating a phosphonitrile halide with a saturated alcohol, treating the halogen containing alkoxy derivative thus obtained with an unsaturated alcohol, and copolymerizing the alkyl substituted alkoxy derivative product thus obtained with an unsaturated acid, forming an alkaline aqueous solution-suspension adapted to be easily and intimately mixed with alkaline aqueous solutions of cellulose xantogenate to obtain a viscous mass of cospinnable components which are co-coagulable in a cellulose xantogenate coagulating bath. Obtaining essentially homogeneous yarns including the flameproofing compound in their cross-sections.

Abstract: A process for preparing alpha , omega -dicarboxylic acids of the formula HOOC-(CH2)n-COOH in which n=6 to 10 is disclosed. The process consists of the catalytic oxidation of a compound of formula X-(CH2)n-CHO wherein X is CHO or COOH and n is 6 to 10 by O2 pure or in mixture with inert gas, possibly under pressure, in at least one polar solvent, at a temperature comprised between 20 DEG and 90 DEG C. and in the presence of a catalyst. The catalyst is chosen from the group consisting of at least one cobalt (II) salt and one ferrous salt. The amount of the catalyst is
