In the example being discussed, vinyl acetate monomer is a prochiral species for 20 Evolution of the Chemical Industry hydroformylation. 1. Therefore, two stereoisomers, R and S, 2-acetoxy propanal, are possible. The stereoselectivity would consequently be decided by the relative amounts of the R- and S-2-acetoxy propanals formed during the asymmetric hydroformylation reaction. 5 Importance of Advanced Instrumental Techniques in Understanding Catalytic Phenomena Advances in instrumental techniques have given a major boost to understanding of catalysis science.

In the case of zeolites, the shape and size of pores allow shape selectivity because the active sites in the pores of the zeolites are tailored for the ­reactant of choice. In view of this, many reactions that involve isomers/reactants of different sizes use specific zeolites to keep undesired reactants out of the scene of the reaction. 6 Role of Nanotechnology in Catalysis As mentioned earlier, in the majority of heterogeneous-catalyzed reactions, a catalyst with high surface area is preferred because it presents a very large number of active sites.
