  organic laboratory techniques: Green Chemistry Experiments in Undergraduate Laboratories Jodie T. Fahey, 2018-02-02 Since the introduction of green chemistry principles in industrial processes, interest has continued to grow and green chemistry has started to take roots in educational laboratories of all disciplines of chemistry. Entire courses centered around green chemistry are becoming more prevalent. By introducing students to green chemistry at a collegiate level, they will better be prepared for industry, graduate schools, and also have a better appreciation for the environment. This book includes experiments that cover a range of green chemistry principles, particularly in the field of organic chemistry. Green chemistry, as we know it today, revolves around a set of twelve principles that were outlined 1998. The experiments presented in this text utilize many of the 12 Principles of Green Chemistry. Each chapter presents an experiment that utilizes at least one, if not more, of these principles. This book is targeted for any professor who would like to introduce green or greener laboratory experiments for their students in any chemistry course regardless of level. The book is designed to introduce students to the ideas, principles, and benefits of green chemistry and inspire educators to adopt more green chemistry principles in their course.

  organic laboratory techniques: Environmental Chemical Analysis S. Mitra, B.B. Kebbekus, 2018-10-03 The study of the environment requires the reliable and accurate measurement of extremely small quantities of chemicals and the ability to determine if they are pollutants or naturally occurring species. Historically, a dilute and disperse method of waste disposal has been accepted; yet as we learn the long-term consequences of such an approach, it is clear that more rigorous waste management techniques are necessary to understand the sources and fates of contaminants and to regulate their discharge. This volume presents the details of the basic analytical science involved in making these measurements. It concentrates on the basic principles of sampling and sample preparation, followed by the chemical principles of the major instrumental methods used in chemical analysis, and detailed discussions of the major environmental matrices. This book also provides coverage of topics usually only partially discussed in textbooks, such as quality assurance plans and statistical data handling. Students majoring in environmental sciences need a foundation in measurement techniques used in the field. Environmental Chemical Analysis gives students a thorough grounding in this field and enough information to judge the quality and interpret the information produced in the analytical laboratory.
  organic laboratory techniques: Experimental Organic Chemistry Clark F. Most, 1988-02-09 Acquaints students with all basic laboratory procedures, coordinating enough theory and technique to enable readers to fully comprehend the reactions being studied and the procedures involved. Material is organized in four sections: techniques, experiments, organic qualitative analysis, and appendixes. The first section introduces students to all common organic techniques and provides an illustrative experiment with each. A unique format helps train the research-oriented student to look for relationships that are not immediately apparent. The experiments section moves on to more complex experiments involving synthetic procedures followed by work-up and analysis requiring more than one technique. Instructions are complete and easy to follow, and a set of pre-laboratory experiments encourages students to determine goals before beginning lab work. The appendixes cover less-referred-to techniques: sublimation, density determination, and molecular weight determinations; and contaion a pronunciation guide and a compilation of chemical hazards.
