摘要： 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.

摘要： A process for semiquantitative colorimetric detection of organic peroxides, especially ether peroxides, with the aid of peroxide indicating means comprising an absorbent carrier impregnated with peroxides, a colorimetric indicator, optionally a buffer, and optionally other additives. The indicating means is immersed in a solution of peroxides in a volatile organic solvent having a boiling point of below 80 DEG C., preferably of below 50 DEG C., and withdrawn. The indicating means is placed in a water vapor atmosphere having a relatively constant temperature between about 20 and 100 DEG C. to evaporate the organic solvent and deposit moisture on the surface thereof, and then examined for color change.

摘要： A process is disclosed for the preparation of granular or pulverulent organic peroxides which are solid at temperatures ranging from -20 DEG to 55 DEG C by solidifying the peroxide in liquid form with a liquid cooling medium which at most hardly dissolves the peroxide, which is liquid at a temperature of -20 DEG C or lower, and which is gaseous at the storage temperature of the peroxide to be solidified. An example of the liquid cooling medium is liquid nitrogen and an example of the organic peroxide is diisopropylperoxydicarbonate. The present process permits the formation of granular or pulverulent solid organic peroxides without traces of liquid peroxide which can cause safety problems.

摘要： New organic peroxides having the formula ##EQU1## may be prepared by reacting a monohydroperoxide selected from R.sub.5 OOH and R.sub.6 OOH with an unsaturated carbonyl compound having the formula ##EQU2## the reaction being carried out in the presence of an acid catalyst at a temperature between about -30.degree.C and +80.degree.C, the molar ratio of the carbonyl compound to the hydroperoxide being between about 1:2 and 1:10. The new organic peroxides are particularly useful for crosslinking plastomers, vulcanizing elastomers, and as initiators for radical polymerizations.
