AI Technical Summary
Technical Problem
Existing isooctene hydroformylation reactions suffer from low conversion rates and product selectivity, high catalyst production costs, and difficulties in catalyst separation.
Method used
A hypercrosslinked microporous polymer phosphine ligand-Rh catalyst is used. By loading the metal active component Rh onto the hypercrosslinked microporous polymer phosphine ligand, a heterogeneous catalyst is formed, which utilizes its highly ordered crystal structure and large surface area to carry out the hydroformylation reaction.
Benefits of technology
This method enables easy separation and recycling of the catalyst and reaction solution, improves the conversion rate of isooctene and the selectivity of isononal, and simplifies the catalyst preparation process.
