WebAug 1, 2024 · Abstract. The isomerization and hydroformylation of butene under the catalysis of Rh-BIPHEPHOS were investigated by varying the butene feed and reaction temperature. The results indicate that in the presence of syngas, with 1-butene as feed, more isomerization product (i.e. 2-butene) is detected in comparison with the … WebHydroformylation, or Oxo Synthesis, is used for the production of aldehydes from alkene compounds. The reaction is catalyzed by organorhodium or organocobalt compounds and adds a hydrogen atom to the C=C bond to form a C-C bond and a formyl group to the molecule, creating an aldehyde. Aldehyde compounds formed by hydroformylation are …
