- Green synthesis method of carbazole oxime ester photoinitiator
-
The invention discloses a green synthesis method of a carbazole oxime ester photoinitiator. According to the method, N-ethyl carbazole is taken as the raw material; then N-ethyl carbazole carries out condensation reactions with o-toluoyl chloride and acetic anhydride/acetyl chloride in the presence of a zirconium catalyst, and finally the condensation reaction product is oximated and esterified to obtain the carbazole oxime ester photoinitiator. The synthesis method does not need high temperature and high pressure, the conditions are mild, and thus the synthesis method is very safe. During the synthesis process, a zirconium catalyst is used, no aluminum chloride or zinc wastewater is generated therefore, the generated byproducts can be recovered, moreover, no solvent that is harmful to the environment is used, and the synthesis method is environment-friendly and is suitable for industrial production.
