At present, the industrial method for preparing α-hydroxyarylketone photoinitiators is: using benzene as raw material, the phenyl ketone intermediate is prepared by Fu’s acylation reaction with acyl chloride catalyzed by lewis acid, and then replaced by halogen (bromine or chlorine), and finally hydrolyzed under the action of concentrated alkali (sodium hydroxide).
Frequently Asked Questions
Q: What is a UV curing initiator?
A: The photocuring system mainly includes photoinitiators, reactive diluents, oligomers, auxiliary agents and other components. Among them, photoinitiators (also known as photosensitizers or photocuring agents) refer to a class of photoinitiators that can be used in the UV (250 ~420nm) or the visible light region (400~800nm) absorbs energy to produce free radicals, cations and other compounds that initiate monomer polymerization, crosslinking and curing. However, the wavelengths absorbed by different photoinitiators are different. The classification of photoinitiators can be mainly divided into two categories: free radical and ionic. Free radicals can be divided into type I and type II; ionic types can be divided into cationic and anionic. The photoinitiator is the starting point of the formulation, and the final use is affected by the performance requirements and the formulation system. There is only the most suitable photoinitiator, not the best photoinitiator.
Q: What are the areas of action of UV curing initiators?
A: The initiator is located in the middle and upper reaches of the industrial chain. The raw materials of the photocuring industry chain are mainly basic chemical materials and special chemicals, etc., and photoinitiators are located in the middle and upper reaches of the industry chain. The mercapto compound series products can be used as photoinitiator raw materials, and are mainly used in the fields of medicine and pesticide manufacturing; photoinitiators are used in many fields such as photoresists and supporting chemicals, UV coatings, UV inks, etc., and the terminal applications span electronic products , home decoration and building materials, medicine and medical treatment, etc.
