Cationic photoinitiator. Photoacid generator. | [Synthesis]
Add a mixed compound solvent ethyl acetate and water solution into a 1L four-neck flask equipped with a stirring blade, condenser tube, and thermometer, and turn on the stirring. Add triphenylthiobromide to the system, slowly add sodium perfluorobutane sulfonate to the reaction system, and raise the temperature to 60°C. Incubate the reaction for 9 hours, monitor its progress, take samples to detect completion, and cool it to 0-5°C—centrifugation to obtain wet crude triphenyl sulfur perfluorobutane sulfonium salt. The crude product was recrystallized with a mixed solution of n-butanol and water under stirring at 85°C for 40min, and after cooling to 0-5°C, the obtained solid was dried below 80°C to obtain 150.32g of solid product. The product yield was 81.17%.
