Preface

In the wake of more stringent health and environment concerns, the world requires more and clearer awareness about the production of valuable chemicals from bio-resources or natural products as well as the use of these natural products in areas of health and environment. With this objective in mind, *Ethanol and Glycerol Chemistry – Production, Modelling, Applications, and Technological Aspects*, discusses the green production of ethanol and glycerol by feasible methods and their possible applications in medical sciences and for environmentally friendly fuel production via a practical approach and appropriate modelling.

The book is organized into three sections and nine chapters contributed by authors from around the globe. Section 1, "Production of Ethanol and Glycerol", is an introductory section that includes three chapters. Chapter 1 by Manikandan Kanagasabai et al., focuses on the production of ethanol from bioresources. Chapter 2 by Chakali Ayyanna et al., discusses the production of bioethanol. Chapter 3 by Lethiwe D. Mthembu et al., illustrates the catalyzed production and applications of glycerol.

Section 2, "Conversion of Glycerol into Aromatic Compounds", focuses on the transformation of glycerol into valuable organic products and includes two chapters. Chapter 4 by Israel Pala-Rosas et al., describes the synthesis of pyridine bases from glycerol using sustainable methods. Chapter 5 by Patrick U. Okoye et al., deals with the preparation of bio-based aromatics via catalytic transformation of glycerol.

Section 3, "Applications", includes four chapters on applications of ethanol in medical sciences. Chapter 6 by Ali Amoushahi et al., illustrates the utility of ethanol inhalation in the treatment and prevention of COVID-19. Chapter 7 by Steven W. Stogner et al., focuses on the use of an old treatment, nebulized ethanol, for a new disease. Chapter 8 by Pietro Salvatori et al., theoretically describes the utility of ethanol inhalation for the disinfection of SARS-COV-2-contaminated airways. Finally, Chapter 9 contributed by Guilherme D. Machado et al., illustrates the modelling of Ethanol to predict the Liquid-Liquid Equilibrium in Food and Fuel Systems.

We congratulate all the authors for providing quality data, research, and analysis and participating in this volume. We would like to thank the staff at IntechOpen, especially Author Service Managers Ms. Marija Nezirovic, Ms. Martina Ivancic, Ms. Nika Karamatic, and Ms. Ana Javor.
