It is reported that the ammonolsis rate of aliphatic acid esters is very slow than that of aliphatic acids. Authors carried out experiments on amidation of methylated aliphatic acid in the flow reactor system, semi-batch reactor system and in the batch reactor system. As a result, it was found a very interesting phenomenon at the semi-batch system mentioned above. Starting from the materials, using palmitic acid methylate, azelaic acid dimethylate, azelaic acid semi-methylate and adipic acid dimethylate, these were charged into the heated reactor respectively, and ammonia was blown into the reactor at a constant velocity. In these reactions, when the same or different sort of aliphatic acid was added, it was found that the ammonolysis rate of these esters could be very fast and that the reaction rate of aliphatic acids was later than that of those esters. This paper reports on the effect of added aliphatic acids in the amidation of methylated fatty acid.
