    Abstract: A method is disclosed for the production of peroxide-like derivatives of ozonides by ozonization of the correspoding olefins, comprising the step of placing an olefin in the presence of ozone in solution in a solvent mixture which comprises at least a nonpolar solvent (inert with respect to the olefin concerned) and at least a polar solvent, in which the as formed ozonide is reactively dissolved, a heavy weight phase being formed which contains the peroxide-like derivative. The derivative in question is removed from the reaction environment so as to substract it from superoxidation and polymerization effects.

    Abstract: AN IMPROVED METHOD FOR POLYMERIZATION OR COPOLYMERIZATION OF ACRYLONITRILE IS DISCLOSED, OF THE KIND IN WHICH THE POLYMERIZATION STEP IS CARRIED OUT WITHIN A POLAR ORGANIC SOLVENT, WHEREIN THE CATALYST SYSTEM IS OF THE SOCALLED REDOX TYPE AND COMPRISES A PEROXIDE, A REDUCING AGENT, A FIRST METAL, A SECOND METAL AND A POLYMERIZATION STOPPER WHICH IS SOLUBLE IN THE POLAR ORGANIC SOLVENT. ALSO THE METALS OR THEIR COMPOUND MUST BE SOLUBLE IN THE ORGANIC POLAR SOLVENT AFORESAID. THE METALS ARE COPPER AS A FIRST METAL AND IRON OR CERIUM AS THE SECOND METAL. THE STOPPER SHOULD ALSO BE A SEQUESTING AGENT FOR METALS. THE PREFERRED STOPPERS ARE SOME DERIVATIVES OF ETHYLENE DIAMINO TETRA ACETIC ACID; A FEW OF THESE DERIVATIVES, SUCH AS THE NITRATE, THE CHLORIDE AND THE PHOSPHATE OF EDTA HAVE NOT YET BEEN DESCRIBED HERETOFORE IN THE TECHNICAL LITERATURE. THE ADVANTAGE OBTAINED WITH THE METHOD AND THE COMPOUNDS OF THE INVENTION IS THAT ACRYLONITRILE COPOLYMERS AND COPOLYMERS ARE OBTAINED, WHICH SHOW IMPROVED PHYSICAL PROPERTIES AND A HIGHEST WHITENESS RATING.

    Abstract: The specification describes a process for preparing saturated omega-aminoacids from olefinically unsaturated omega-aldehydoacids. According to the invention, the starting aldehydoacid is transformed into the corresponding iminoacid, and this is subjected to the hydrogenation both of the imino function and of the ethylenic double bond or double bonds, in a single stage and in the presence of an hydrogenation catalyst. The catalyst is a transition metal of one of the first two sub-groups of the VIII group of the periodic system, viz. is chosen among Fe, Ru, Os, Co, Rh, and Ir, and is used in the metal state or as a compound.

    Abstract: There is described a procedure for preparing unsaturated or saturated alpha , omega -dialdehydes, wherein the monoozonide of the corresponding olefine undergoes hydrogenation in a solution and in presence of a catalyst system comprising (A) a noble metal comprising palladium or platinum and carried on a carrier comprising alumina, coal or barium sulphate, and (B) at least one compound of a heavy metal, and wherein, when a saturated dialdehyde is to be prepared, the unsaturated dialdehyde prepared as above undergoes a further catalytic hydrogenation in an organic solvent after removal of component (B) of the said system by means of a treatment with an ion-exchange resin acidified with sulphuric acid, the resin being of such quantity that the acid equivalents of the resin are at least equal to the equivalents of the heavy metal in the component (B) of said catalytic system.
