Abstract
U okviru ovog rada istražena je kinetika reakcije dimerizacije m-halogennitrozobenzena u ĉvrstom stanju. m-Klor- i m-bromnitrozobenzen pripremljeni su oksidacijom odgovarajućih amino derivata te su izolirani u obliku E-dimera kristalizacijom iz otopine. Sublimacijom mhalogennitrozobenzena pri sniženom tlaku pripremljena je smjesa Z- i E-dimera. Fotodisocijacijom E-dimera te smjese Z- i E-dimera u KBr pastili pri kriogenim uvjetima pripremljeni su monomeri m-halogennitrozobenzena. Kinetike reakcija dimerizacije nakon kriogene fotodisocijacije dimera praćene su na nekoliko razliĉitih temperatura vremenski razluĉenom IR spektroskopijom. Iz temperaturne ovisnosti konstanti brzina reakcija odreĊeni su aktivacijski parametri za reakciju dimerizacije monomera m-halogennitrozobenzena u ĉvrstom stanju.
Abstract (english)
In this diploma thesis, kinetics of dimerization reactions of m-halogenonitrosobenzenes in solid state were studied. m-Chloro- and m-bromonitrosobenzene were prepared by oxidation of the corresponding amino derivatives and were isolated in the form of E-dimers by crystallization from the solution. Mixture of Z- and E-dimers was prepared by sublimation of m-halogenonitrosobenzenes under reduced pressure. Monomers of mhalogenonitrosobenzenes were prepared by cryogenic photodissociation of dimers in KBr pellet. Kinetics of dimerization reactions after cryogenic photodissociation were followed by using time-resolved IR spectroscopy at various temperatures. From the temperature dependence of the reaction rate constants, the activation parameters for the reaction of dimerization of m-halogenonitrosobenzenes monomers were estimated in solid state.
