- Ketone oxime ester photoinitiator green synthetic method
-
The present invention discloses a ketone oxime ester photoinitiator green synthetic method. According to the method, diphenyl sulfide as a raw material is condensed with caprylyl chloride under the effect of a zirconium catalyst, and then a ketone oxime ester photoinitiator can be obtained by oximation and esterification. The method does not relate to high temperature and high pressure reaction, and is mild in reaction conditions, and good in security. No aluminum chloride or zinc waste water is produced due to use of the zirconium catalyst during the synthesis process, produced byproducts can be recycled, no environmentally harmful solvent is used, and the ketone oxime ester photoinitiator green synthetic method is environmentally friendly, and therefore suitable for industrial production.
