1. a hydroformylation process, comprising:

  • I. cycloolefin is added in rhodium catalyst solution, and under hydrogen and carbon monoxide, heat this rhodium catalyst solution to carry out hydroformylation reaction, make this cycloolefin form cycloalkanes aldehyde, this cycloolefin comprises Dicyclopentadiene (DCPD), three cyclopentadiene, two cyclohexadiene or hexamethylene olefine aldehydr;

    Ii. the first layer and the second layer is divided into after the extraction liquid that to add containing carbon number be the first ring alkanol of 5 ~ 19 mixes with this rhodium catalyst solution, wherein this first layer comprises in fact this rhodium catalyst solution, and this second layer comprises in fact this extraction liquid containing first ring alkanol and this cycloalkanes aldehyde;

    Iii. this first layer and this second layer solution is separated;

    AndThis second layer is carried out hydrogenation, and make this cycloalkanes aldehyde form the second cycloalkanol, wherein this first ring alkanol is identical with the chemical structure of this second cycloalkanol.
