Procedure for the obtaining of 5-amino-4-cyano-1- (2,4,6-trichlorophenyl) pirazol or one of its salts. It consists of the reaction of 2,4,6-triclorophenyl hydrazzine with a lower alcoholethylenomalononitril, whose bottom alcoxy group contains 1-4 carbon atoms. The reaction is carried out in a polar solution, inert, like ethanol, at a temperature comprised between 3 and 150 c. These compounds have applications in agriculture as herbicides and regulators of the growth of the plants. (Machine-translation by Google Translate, not legally binding)
