Definition & Meaning | English word DERACEMIZATION

Definitions of DERACEMIZATION

1. (chemistry) The conversion of a racemate into a pure enantiomer or into a mixture in which one enantiomer is present in excess, or of a diastereoisomeric mixture into a single diastereoisomer or into a mixture in which one diastereoisomer predominates

Examples of Using DERACEMIZATION in a Sentence

• Viedma ripening or attrition-enhanced deracemization is a chiral symmetry breaking phenomenon observed in solid/liquid mixtures of enantiomorphous (racemic conglomerate) crystals that are subjected to comminution.
• Percec has made scientific contributions in diverse areas, including the discovery of all helical stereoisomers of polyphenylacetylene, their interconversion and intramolecular electrocyclization with applications in chiral separation, sensors, membranes, molecular machines, the discovery of liquid crystals based on conformational isomerism: polyethers, poly(vinyl ether)s, macrocyclics, covalent and supramolecular dendrimers He revealed double-helices disregarding chirality and deracemization in crystal state, designed the sequence-rearrangement concept to transform dynamic racemic (atactic) into homochiral (isotactic) supramolecular polymers and demonstrated acceleration of self-assembly and disassembly by fluorine and fluorous phase.
