Preferably, double [4 '-(2, the 2- dimethoxy acetyl) phenyl] methane of the compound of formation and double [4 '-(2,2- diethyls
Oxygroup acetyl) phenyl] methane both functions as photoinitiator.
A kind of double [4 '-(the 2,2- dialkoxies acetyl) phenyl] methane of photoinitiator containing unsaturated allyl compound or are containing
There is the application in the photoinitiator of the light polymerization of the mixture of the compound.
The synthetic method of double [4 '-(2, the 2- dialkoxy acetyl) phenyl] methane of a kind of photoinitiator, using two (4- diethyls
Aminosulfonylphenyl) methane is raw material, reacted under the action of hydrogen chloride with nitrous ether (ethyl nitrite) or methyl nitrite, generation it is double [4 '-
(2,2- dialkoxy acetyl) phenyl] methane, reaction temperature is 35-40 DEG C, when the reaction time is 4 small.
The advantages and positive effects of the present invention are：
1st, the invention discloses a kind of new photoinitiator double [4 '-(2,2- dialkoxy second friendly to environment and health
Acyl) phenyl] methane compares with traditional initiator, and such initiator has difunctional, unsaturated allyl compound can be made to exist
Light irradiation is lower to occur quick polymerisation, can be widely applied in photopolymerization reaction material.
2nd, the present invention optimizes reaction condition, provides a simple and direct and warp by the change to reaction raw materials and condition
The production technology of Ji material benefit.
