In the field of organic synthesis, triphenylphosphine rhodium chloride is widely used in the hydrogenation of olefin. Its high catalytic activity and mild reaction conditions make many previously difficult hydrogenation reactions proceed smoothly. In addition, the catalyst can also catalyze various reactions of unsaturated compounds, such as hydrosilanization, hydroformylation, borohydride, isomerization, cycloaddition and carbonylation reactions. These reactions are of great significance in drug synthesis, fine chemical production and polymer material preparation.In the petrochemical field, triphenylphosphine rhodium chloride is also used as a paraffin hydrogenation catalyst. Through its catalytic effect, the quality and performance of paraffin products can be significantly improved to meet the demand for high-quality paraffin in different fields. In the field of materials science, the catalytic effect of triphenylphosphine rhodium chloride cannot be ignored.
