The invention discloses a preparation method of a triphenylphosphine polymer self-supporting heterogeneous catalyst whose structure and performance can be adjusted. As an active component, a phosphine-containing porous organic polymer with a hierarchical pore structure is used as a carrier, and the phosphine-containing organic polymer is polymerized from vinyl-functionalized triphenylphosphine. Such coordination bond heterogeneous catalysts are suitable for reactors such as fixed bed, slurry bed, bubbling bed and trickle bed. The heterogeneous catalyst provided by the invention has the characteristics of adjustable structure and catalytic performance, and the catalyst has good stability and is easy to be separated and recovered. |
