Abstract
U ovom radu je istražena kinetika reakcija dimerizacije p-jod- i p-klornitrozobenzena te disocijacije E-dimera p-jodnitrozobenzena u čvrstom stanju. p-Jod- i p-klornitrozobenzen pripravljeni su oksidacijom odgovarajućih amino derivata mehanokemijski odnosno u otopini. E-dimer p-jodnitrozobenzena pripravljen je kristalizacijom iz otopine. Kinetika dimerizacije p-jod- i p-klornitrozobenzena istražena je nakon fotodisocijacije dimera u KBr pastili pri kriogenim uvjetima. Također je istražena mogućnost dimerizacije p-klornitrozobenzena nakon kriogene depozicije para monomera na pločicu cezijeva jodida. Kinetike reakcija dimerizacije i disocijacije praćene su pri različitim temperaturama vremenski razlučenom IR spektroskopijom. Iz temperaturne ovisnosti koeficijenata brzina reakcija određeni su aktivacijski parametri za reakciju dimerizacije monomera i disocijacije dimera phalogennitrozobenzena.
Abstract (english)
In this work, kinetics of dimerization reactions of p-iodo- and p-chloronitrosobenzene and dissociation of E-dimer of p-iodonitrosobenzene in solid state were studied. p-Iodo- and p-chloronitrosobenzene were prepared by oxidation of corresponding amino derivatives by mechanochemical synthesis and in a solution. E-dimer of p-iodonitrosobenzene was prepared by crystallization from the solution. Kinetics of dimerization of p-iodo- and pchloronitrosobenzene was investigated after photodissociation of dimers in KBr pellet under cryogenic conditions. In addition, the possibility of dimerization of p-chloronitrosobenzene after cryogenic deposition of monomer molecules on the cesium iodide surface was studied. Kinetics of dimerization and dissociation reactions were followed at different temperatures by using time-resolved IR spectroscopy. From the temperature dependence of the reaction rate constants, the activation parameters for the reaction of dimerization of monomers and dissociation of dimers of p-halogenonitrosobenzenes were estimated.
