Magnetic nano catalyst modified by dendrimer has excellent performance.

Magnetic nano catalyst modified by dendrimer has excellent performance: 1. better stability 2. better solubility, can be dissolved in many organic solvents 3. higher catalytic activity 4. higher catalytic selectivity. In a variety of organic solvents, it can catalyze a variety of substance in the hydroformylation reaction, such as catalytic styrene, 4 – fluoro-styrene, bromostyrene, etc., in appropriate conditions, conversion rate can reach 100%, the performance of selectivity reaches 98%, in addition, magnetic nanoparticle catalysts modified by dendrimer, can be recycled to reuse, after recycled five times it can still maintain excellent catalytic activity. Weihai CY Dendrimer Technology Co., Ltd.-Professional Manufacturer for low cost dendritic polymers. -The newest 4th class polymers.
