B01J2231/347 - CPC Classification

Classification description:

Catalytic reactions performed with catalysts classified in; Addition reactions at carbon centres, i.e. to either C-C or C-X multiple bonds; Other additions, e.g. Monsanto-type carbonylations, addition to 1,2-C=X or 1,2-C-X triplebonds, additions to 1,4-C=C-C=X or 1,4-C=-C-X triple bonds with X, e.g. O, S, NH/N 1,2-additions, e.g. aldol or Knoevenagel condensations via cationic intermediates, e.g. bisphenol A type processes
