Abstract
Zbog današnje potrebe za smanjenjem negativnih utjecaja na okoliš i količine otapala u kemijskim reakcijama sve se više okrećemo novim, alternativnim metodama dobivanja spojeva. Mehanokemijska sinteza je jedan od tih načina. Umjesto da se kemijske reakcije, kao što je to do sad bio običaj, izvode pomoću raznoraznih, najčešće organskih otapala koja mogu biti toksična, te podrazumijevaju velike unose energije i kasnije otpad koji treba zbrinuti, mehanokemija se javlja kao energetski učinkovita alternativa i omogućava istraživanje kemijskih reakcija bez upotrebe skupih i opasnih otapala. U ovome su radu mehanokemijskom sintezom pripravljene Schiffove baze izvedene iz dialdehida i diamina ručnim usitnjavanjem u tarioniku. Analiza produkata vršila se IR spektroskopijom i termičkom analizom pri čemu je ustanovljeno da je moguće dobiti željene produkte u visokom prinosu.

Due to today's need to reduce negative impacts on the environment of solvents usage in chemical reactions we are increasingly turning to new alternative methods of preparing the compounds. Solvent free synthesis is one of those ways. Instead of chemical reactions, like it was the case so far, that are performed in various, mostly organic solvents, that are toxic and include large inputs of energy and subsequent waste that must be disposed of. Solvent free synthesis occurs as an energy efficient alternative that allows the study of chemical reaction without the use of expensive and hazardous solvents. Herein we demonstrate the classical solvent free synthesis of Schiff bases derived from dialdehyde and diamine by grinding in a mortar by hand. The prepared compounds were characterized by IR spectroscopy and thermal analysis (TGA-DSC) wherein is establish that it is possible to obtain the desired products in high yield.
