Abstract

The invention belongs to aromatic ketone compounds, specifically relating to an aromatic ketone coumpound photoinitiator for ultraviolet light radiation solidification and method of manufacturing the same. The method consists of the following two typical steps: a first step of coverting the organic carboxyl acid coumpound into the corresponding acyl chloride intermediate under the action of thionyl chloride, and then the intermediate, without a separation and purifying process, directly performing Friedman-Crafts acylation reaction with biphenyl or disubstituted benzene compounds under the action of the equivalent or catalytic amount of Lewis acid type promotor to couple and obtain aromatic ketone coumpounds; a second step of performing soda treatment to a hydroxy-substituted aromatic ketone raw material to obtain its ion salt, the salt reacts with halogenated hydrocarbon, acyl chloride or other electrophilic reagents to obtain aromatic ketone compounds.

Description

【Technical field】

[0001] The invention belongs to aromatic ketone compounds, in particular to a photoinitiator of aromatic ketone compounds used for ultraviolet light curing, and a method for producing the aromatic ketone compounds. 【Background technique】

[0002] The UV radiation curing process is a photochemical reaction process. Taking ultraviolet ink technology as an example, under the action of ultraviolet energy, the prepolymer is cured into a film in a very short time. The photocuring mechanism of UV ink is divided into four types: free radical polymerization, free radical addition, cationic polymerization and acid curing. The most widely used type of ink. Under the irradiation of ultraviolet light, the photopolymerization initiator in the ultraviolet ink absorbs photons of a certain wavelength and turns into free molecules, which become free radicals, and then through the transfer of intermolecular energy, the polymerizable prepolymer and photosensitive monomer bec...
