Research Interests
Dr. Liotta’s research activities involve both synthetic-organic and physical-organic chemistry. His major interests lie in the areas of structure-property relationships, kinetics and mechanisms of organic reactions, asymmetric synthesis, homogeneous and heterogeneous catalysis (phase transfer catalysis), the development of environmentally benign tunable (supercritical fluids, near critical water, gas expanded liquids)and smart (reversible ionic liquids, DMSO substitutes) solvent systems, and molecular thermodynamics, solution theory, and phase equilibria. A fundamental goal of Dr. Liotta’s research is the development of sustainable and environmentally benign chemicals and chemical processes. Dr. Liotta has been collaborating with Dr. Charles A. Eckert for approximately 20 years.
Dr. Liotta's research group presently consists of five graduate students and five post-doctoral associates in the School of Chemistry and Biochemistry and seven graduate students and one post-doctoral associate in the School of Chemical Engineering (joint with Prof. Charles A Eckert).
During the past forty-four years, Dr. Liotta has presented over four hundred research seminars at various universities, colleges, chemical companies, symposia, professional meetings (ACS), Gordon Conferences, etc. in North America, Europe, Africa, Central America and Asia.
