  • Patent number: 4267347
    Abstract: Process for the preparation of 1,2,4-triazole comprises contacting hydrazine or its aqueous solutions with at least about 2.5 moles of formamide at a temperature of 140.degree. to 210.degree. C. and then recovering the resultant 1,2,4-triazole in yields of 92-98% with 94-98% purity. The formamide is maintained in an excess over about the 2.5 molar amount consumed in the reaction with the hydrazine. Recovery steps for isolating the 1,2,4-triazole are disclosed.

  • Patent number: 4163848
    Abstract: Production of 2-alkyl- or cycloalkyl-4-methyl-6-hydroxypyrimidines by first neutralizing an alkyl imidate ester hydrochloride with a base in the presence of a water-immiscible solvent for the alkyl imidate ester to be freed thereby; condensing the alkyl imidate ester with diketene to form an oxazinone intermediate, which is then reacted in organic solution with gaseous ammonia and recovering the desired substituted 6-hydroxypyrimidine.

  • Patent number: 4052396
    Abstract: Production of 2-alkyl or 2-cycloalkyl-4-methyl-6-hydroxy pyrimidines by first reacting diketene and lower alkanoic or cycloalkanoic acid nitriles in the presence of catalytic amounts of Bronsted or Lewis acids, followed by treating the diketene/nitrile reaction product with ammonia in the presence of acid catalysts.
