Abstract
New manufacturing process for 3-5-pyrazolidones characterized by comprising in combination a previous solution of 10 parts of sodium 3n 500-600 parts of a solvent alcohol containing more than 3 carbon atoms such as butyl or amyl alcohol that gives rise to to obtain the corresponding sodium butylate or amylate as condensing medium; the successive addition of a mechanical ester such as ethyl malonate, ethyl n-butylmalonic or ethyl isobutyl malonate and 84 8 parts of a substance such as symmetric diphenylbidrazide; the reaction of the malonic ester and the symmetrical diphenylhydrazide in the presence of the alcoholate and the separation and purification of the compound resulting from the reaction.
