The invention relates to a kind of α - amino ethyl ketone photoinitiator intermediate preparation method, in particular to photoinitiator 2 - benzyl - 2 - dimethylamino - 1 - (4 - morpholino phenyl) butanone and 2 - (4 - methyl benzyl) - 2 - dimethylamino - 1 - (4 - morpholino phenyl) butanone intermediate 1 - (4 - morpholino-phenyl) - 1 - butanone. To overcome the shortcomings of the prior art, provides a does not need to add the heavy metal catalyst, does not need high-temperature high-pressure feeding, after treatment is simple, the appearance of the product is good, is suitable for the industrial production of α - amino ethyl ketone photoinitiator preparation method of the midbody.

, (2018/09/08)
The invention discloses a synthetic method of 2-benzyl-2-dimethylamino-1-(4-morpholinophenyl) butanone. The synthetic method comprises the following steps: (1) carrying out a Friedel-Crafts reaction on chlorobenzene with n-butyryl chloride under the catalysis of aluminium trichloride to obtain a compound I; (2) carrying out a bromination reaction on the compound I with bromine under the action ofa catalytic oxidizing agent to obtain a compound II; (3) carrying out a substitution reaction on the compound II with dimethylamine to obtain a compound III; (4) carrying out a quaternization reactionon the compound III with benzyl chloride to obtain a compound IV; (5) carrying out a substitution reaction on the compound IV with morpholine under the action of a composite catalyst to obtain a compound V; and (6) carrying out a rearrangement reaction on the compound V under the action of an alkali so as to obtain the 2-benzyl-2-dimethylamino-1-(4-morpholinophenyl) butanone. The synthetic methodprovided by the invention has the advantages of mild technological condition, simple operation, high selectivity and high total yield.

The present invention improves curability and reduces post-curing migration in a photopolymerization initiator. As a photopolymerization initiator, the present invention uses a compound obtained as a result of a Michael addition reaction between an [alpha]-aminoacetophenone skeleton-containing compound (I) represented by general formula (1), and a reactive compound (II) which functions as a Michael acceptor. (In formula (1), R1 represents an aliphatic group or the like, R2-R3 each independently represent an aliphatic group or the like, R4-R7 each independently represent a hydrogen atom or the like, X1 represents a single bond or a C1-6 alkylene group, X2 represents a carbonyl group or the like, and Y1 and Y2 represent a group represented by general formula (2) or the like. Meanwhile, when Y1 and Y2 both have a structure represented by general formula (2), the X5 in one or both is -NH-.) (In general formula (2), X3 and X4 each independently represent a C2-6 straight-chain or branched alkylene group or the like, and X5 represents a single bond, -O-, or -NH-.)
