Abstract
U prijavi je opisan postupak za sintezu hidrazida nikotinskih kiselina opšte formule (1) gde R1 predstavlja C(=O)NHNH2 grupu ili vodonikov atom, a R2 vodonikov atom ili C(=O)NHNH2 grupu, iz cijano-piridina opšte formule (2) gde R1 predstavlja cijano-grupu ili vodonikov atom, a R2 vodonikov atom ili cijano-grupu, pomoću hidrazin-hidrata u atmosferi vazduha ili inertnog gasa u prisustvu kompozitnog zeolitskog katalizatora i vode.The application describes a process for the synthesis of nicotinic acid hydrazides of general formula (1) wherein R1 represents a C (= O) NHNH2 group or a hydrogen atom and R2 a hydrogen atom or a C (= O) NHNH2 group from cyano-pyridine of the general formula (2) ) where R1 represents a cyano group or hydrogen atom and R2 represents a hydrogen atom or cyano group, by hydrazine hydrate in an atmosphere of air or inert gas in the presence of a composite zeolite catalyst and water.
