WebRacemization. In chemistry, racemization is a conversion, by heat or by chemical reaction, of an optically active compound into a racemic (optically inactive) form. This creates a 1:1 molar ratio of enantiomers and is referred to as a racemic mixture (i.e. contain equal amount of (+) and (−) forms). dustbuster historyWebThe asymmetric atom is called a chirality center, a type of stereocenter. A ... An example of such an enantiomer is the sedative thalidomide, which was sold in a number of countries around the world from 1957 until 1961.
