Abstract
The invention relates to a 4,4'-bis(2,2-dialkoxyacetyl)biphenyl photocatalyst which may act as a photoinitiator for photopolymerization of an alkene unsaturated compound or a mixture with the same. Compared with traditional photoinitiators, the photocatalyst has double functional groups and enables alkene unsaturated compounds to quickly photopolymerize in light. 4,4'-Diacetylbiphenyl is used as araw material to react with ethyl nitrite (or methyl nitrite) under the action of hydrogen chloride to generate 4,4'-bis(2,2-dialkoxyacetyl)biphenyl. The influence of hydrogen chloride upon the reaction is investigated, and a novel process to synthesize 4,4'-bis(2,2-dialkoxyacetyl)biphenyl with simple operations and good economy and practicality is provided.
