Many natural and artificial flavorings belong to a class of compounds called esters. Esters are produced by a chemical process called esterification, and in this activity, students have the chance to prepare and examine several synthetic flavorings that are esters.
Science offers advances with the introduction of new technologies.
Dowex resin, a product recently developed with new technology, is a less dangerous substitute for concentrated sulfuric acid. Either substance can be used as a catalyst in this activity. Scientific Inquiry Students conduct an investigation to make esters. Students explain how Dowex resin or the sulfuric acid functions as a catalyst in the reactions. Chemical Reactions, Grades 9-12 Chemical reactions occur all around us.
