    摘要： This invention relates to covulcanizable anti-aging agents which can be produced by the reaction of p-phenylenediamines, which are optionally substituted, and/or of sterically hindered phenols, with bifunctional alkyl, aryl and/or aralkyl compounds and by subsequent reaction of the products thus obtained with sulfur and/or sulfur donor compounds. The anti-aging agents according to the present invention maintain their efficacy over a long period of time and are distinguished in particular by the fact that in practice, they are hardly extracted from the vulcanized products by water, by oil and/or petrol, or by hydraulic fluids.

    摘要： A process for preparing S-(&ohgr;-aminoalkylamino) alkyl aryl sulfide dihydrochlorides includes the steps of (a) reacting aryl mercaptan and (&ohgr;-aminoalkylamino) alkylbromide dihydrobromide to cause condensation thereof in the presence of an organic base in an organic solvent and provide a condensation product; (b) converting the condensation product to a dihydrochloride salt; and (c) precipitating the dihydrochloride salt. Preferably the precipitated dihydrochloride salt is recrystallized. These dihydrochlorides are new and effective antidotes for sulfur mustard toxicity.
