Abstract: SUBSTITUTED 3-AMINOINDAZOLES ARE OBTAINED BY REAXTING BENZONITRILE DRRIVATIVES WHICH CONTAIN AN XR-GROUP (X=O, R=ALKYL, ARYL) IN THE 2-POSITIONS, WITH TRONEGATIVE SUBSTITUENT IN THE 3- AND 5-POSITIONS, WITH OPTIONALLY MONOSUBSTITUTED HYDRAZINE, OPTICALLY IN A SOLVENT AND OR IN THE PRESENCE OF CATALYTIC QUANTITIES OF AN ACID. THE RADICALS R IN THE GROUP XR- ARE PREFERABLY ALKYL RADICALS WITH FROM 1 TO 4 CARBON ATOMS AND ARYL RADICALS WITH UP TO 12 CARBON ATOMS. THE COMPOUNDS E.G. 3 - AMINO-5,7-DINITROINADAZOLE ARE SUITABLE FOR USE AS YELLOW, ORANGE OR RED PIGMENTS FOR EXAMPLE FOR DYEING PLASTICS.

Abstract: THIS INVENTION RELATES TO NEW SULPHENAMIDES OF 2FORMYL PROPYL-2-SULPHENIC ACID AND THEIR USE IN THE PRODUCTION AND PROCESSING OF MIXTURES BASED ON A NATURAL OR SYNTHETIC RUBBER. THE NOVEL COMPOUNDS ARE PREPARED BY REACTING 2-FORMYL PROPYL-2-SULPHENIC CHLORIDE WITH AMINES AND AMIDES IN THE PRESENCE OF AN ACID BINDING AGENT. THE RETARDERS CAN BE MIXED INTO THE RUBBER IN THE USUAL WAY.
