Abstract:
A process for preparing 2,6-dialkylcyclohexylamine, e. g. , 2,6-dimethylcyclohexylamine, from a corresponding dialkylphenol, e. g. , 2,6-dimethylphenol, by passing the phenol over a bed of a hydrogen-transfer catalyst in the presence of ammonia at elevated temperatures and pressures.
A process is provided for the manufacture of methomyl oxime comprising the steps of chlorinating acetaldoxime dissolved in N-methylpyrrolidone at a temperature range of -10. degree. C. to 0. degree. C. to form a N-methylpyrrolidone solution of acethydroxamoyl chloride; thioesterifying the acethydroxyamoyl chloride in said solution at a temperature range of about 0. degree. C. to 10. degree. C. at pH in the range 6-7.

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.
