AI Technical Summary
Existing methods for synthesizing hexafluoropropylene trimer suffer from difficulties in obtaining raw materials, harsh reaction conditions, high costs, and significant safety hazards, which limit its industrial production.
A gas-phase reaction system was adopted, and a polymerization catalyst with multiple metals such as Cr, Ni, Fe, Al, Cu, Bi, Zn, Mg, Co, and In as active components was prepared by co-precipitation method. The catalyst was then subjected to gas-phase reaction at 200-800 °C to generate hexafluoropropylene trimer.
This study has developed a method for synthesizing hexafluoropropylene trimer that utilizes inexpensive and readily available raw materials, has a high yield, and is safe for industrial production, thereby reducing production costs and safety risks.
