Abstract
It is known that fatty acid methyl ester and triglyceride can be hydrogenated by treatment with hydrazine, but hydrazide is formed inevitably.
In this paper, it was found that soybean fatty acid methyl ester, methyl linoleate and soybean oil could be hydrogenated without the formation of long chain hydrazide by addition of the carboxylic acid such as acetic acid or propionic acid as part of solvent.
The reaction of hydrazine with propionic acid was attempted to clarify why long chain hydrazide does not form in the reactions using carboxylic acid as part of solvent. As a result, the main reaction product was identified as 1, 2-dipropionyl hydrazine.
