1. A process for preparing a triazolinone of the formula (II) ##STR519## in which R1 represents hydrogen, amino, or represents C1 -C6 -alkyl which is optionally substituted by fluorine, chlorine, bromine, cyano, C1 -C4 -alkoxy, C1 -C4 -alkylcarbonyl or C1 -C4 -alkoxy-carbonyl, or represents C3 -C5 -alkenyl or C3 -C6 -alkinyl, each of which is optionally substituted by fluorine, chlorine and/or bromine, or represents C3 -C5 -cycloalkyl which is optionally substituted by fluorine, chlorine, bromine and/or C1 -C4 -alkyl, or represents phenyl-C1 -C3 -alkyl which is optionally substituted by fluorine, chlorine, bromine, cyano, nitro, C1 -C4 -alkyl, trifluoromethyl C1 -C4 -alkoxy and/or C1 -C4 -alkoxy-carbonyl, or represents phenyl which is optionally substituted by fluorine, chlorine, bromine, cyano, nitro, C1 -C4 -alkyl, trifluoromethyl, C1 -C4 -alkoxy, fluorine- and/or chlorine-substituted C1 -C3 -alkoxy, C1 -C4 -alkylthio, fluorine- and/or chlorine-substituted C1 -C3 -alkylthio, C1 -C4 -alkylsulphinyl, C1 -C4 -alkylsulphonyl and/or C1 -C4 -alkoxy-carbonyl, or represents C1 -C4 -alkylamino which is optionally substituted by fluorine, cyano, C1 -C4 -alkoxy or C1 -C4 -alkoxy-carbonyl, or represents C3 -C6 -cycloalkylamino or di-(C1 -C4 -alkyl)-amino,R2 represents C1 -C6 -alkyl which is optionally substituted by fluorine, chlorine, bromine, cyano, C3-C6 -cycloalkyl, C1 -C4 -alkoxy or C1 -C4 -alkoxycarbonyl, or represents C3 -C6 -alkenyl or C3 -C5 -alkinyl, each of which is optionally substituted by fluorine, chlorine and/or bromine, or represents C3 -C6 -cycloalkyl which is optionally substituted by fluorine, chlorine, bromine and/or C1 -C4 -alkyl, or represents cyclohexenyl, or represents phenyl-C1 -C3 -alkyl which is optionally substituted by fluorine, chlorine, bromine, cyano, nitro, C1 -C4 -alkyl, trifluoromethyl, C1 -C4 -alkoxy and/or C1 -C4 -alkoxy-carbonyl, or represents phenyl which is optionally substituted by fluorine, chlorine, bromine, cyano, nitro, C1 -C4 -alkyl, trifluoromethyl, C1 -C4 -alkoxy, fluorine- and/or-chlorine-substituted C1 -C3 -alkoxy, C1 -C4 -alkylthio, fluorine- and/or chlorine-substituted C1 -C3 -alkylthio, C1 -C4 -alkyl-sulphinyl, C1 -C4 -alkyl-sulphonyl and/or C1 -C4 -alkoxy-carbonyl, which process comprises heating a compound of the formula (IX) ##STR520## in which R27 represents methyl, ethyl or phenyl, at a temperature range of 50°

  • C. to 150°

    C., optionally in the presence of a diluent.
