Abstract	Milling reactions are conducted in high-energy ball mills in a closed assembly comprising of a milling jar, sample, and a milling media. So far, monitoring a reaction course of such reactions required periodic disruption of the milling process and sampling for further ex situ analysis. Thus, information obtained in that way might not reflect the true nature of milling reactions. Recently introduced in situ approach based on synchrotron powder X-ray diffraction and Raman spectroscopy for monitoring milling reactions have been superior to the already established ex situ analysis. This thesis represents a further development of methods for uninterrupted real-time and in situ monitoring of milling reactions. Here, a detail description of experimental setup and data analysis is given, and developed methods were used for studying solid-state synthesis of metal-organic frameworks ZIF-6 and ZIF-8, Knoevenagel condensation between barbituric acid and vanillin, isotope-exchange reactions between benzoic acid and deuterated water, 2-pyridone, or paracetamol, and finally, competitive cocrystallization reactions between nicotinamide and benzoic, anthranilic, or salicylic acid.
Abstract (croatian)	Reakcije mljevenjem odvijaju se u specijaliziranim mlinovima unutar zatvorenih posuda u kojima se nalaze reaktanti i kuglice. Praćenje takvih reakcija je zahtjevalo periodičko zaustavljanje mljevenja i uzorkovanje reakcijske smjese za daljnu anlizu ex situ. Stoga, informacije dobivene na ovaj način ne moraju nužno odgovarati stvarnim kemijskim i fizikalnim procesima koji se odvijaju tijekom reakcije. Nedavno uvedene metode praćenja reakcija mljevenja, temeljene na difrakciji na praškastom uzorku i Ramanovoj spektroskopiji in situ, pokazale su se superiornim u usporedbi s dosad korištenim metodama ex situ. U ovoj disertaciji prikazan je daljnji razvoj metoda za neprekidno praćenje reakcija mljevenja, te je dan detaljan opis eksperimentalnog postava i obrade prikupljenih podataka. Razvijene metode iskorištene su u proučavanju sinteze u čvrstom stanju metalo-organskih mreža ZIF-6 i ZIF-8, Knoevenagelovoj kondenzaciji između barbiturne kiseline i vanilina, reakcijama izmjene izotopa između benzojeve kiseline i deuterirane vode, 2-piridona ili paracetamola, i kompetitivnim reakcijama kokristalizacije između nikotinamida i benzojeve, antranilne ili salicilne kiseline.
