In line with the further thriving demand for downstream derivatives of allyl alcohol, cumene and vinyl acetate monomer worldwide, Chang Chun Group decide to expand the operation of allyl alcohol, cumene and vinyl acetate monomer in Singapore.
Alicyclic compounds can also display cis-trans isomerism. As an example of a geometric isomer due to a ring structure, consider 1,2-dichlorocyclohexane: Optical Isomerism . Main article: Chirality. Optical isomers are stereoisomers formed when asymmetric centers are present, for example, a carbon with four different groups bonded to it. Enantiomers are two optical isomers (i.e. isomers that are reflections of each other). Every stereocenter in one isomer has the opposite configuration in the other.
