Abstract/Description
A greener chemistry method, mechanochemistry involves milling reagents to induce reactions rather than using thermal energy and hazardous solvents which can negatively impact the environment. Mechanochemical alternatives to solution-based synthesis of 1, 3-dimethylbenzimidazolium iodide (HBZM-Me2I) were analyzed to further the study of environmentally sustainable reactions, determine maximum yield, and minimize environmental impact. Successful syntheses of HBZM-Me2I and its derivatives are important as they are useful for antimicrobial agents and are expensive to synthesize on a large scale. Developing new methods of successful synthesis will be a step forward for more practical industrial applications. Unlike typical mechanochemical methods, both liquid and solid reagents were used during this study to reduce hazardous liquids emitted into the waste stream. Through this method, environmental impact was minimized and an eco-friendly method of syntheses of HBZM-Me2I was determined. The results were kinetically analyzed and determined to fit sigmoidal models. Kinetically fitting data provides important information on reaction conversion over time and estimates completion times for future kinetic studies.
