, (2019/05/16)
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.

Paragraph 0003; 0034, (2016/10/07)
The present invention relates to an alpha-amino acetophenone photoinitiator preparation method, particularly to a preparation method of 2-benzyl-2-dimethylamino-1-(4-morpholinophenyl)butanone and 2-(4-methylbenzyl)-2-dimethylamino-1-(4-morpholinophenyl)butanone. According to the present invention, 1-p-fluorophenyl-1-butanone is adopted as the raw material, and only the safe and cheap solvent is used in the whole method to conveniently prepare 2-benzyl-2-dimethylamino-1-(4-morpholinophenyl)butanone and 2-(4-methylbenzyl)-2-dimethylamino-1-(4-morpholinophenyl)butanone; and the method has characteristics of cheap and readily available raw materials, high yield, no requirement of intermediate purification, and continuous reaction without solvent replacement, and is the preparation method with characteristics of low cost, environmental protection and easy operation and suitable for industrialization.

, (2008/06/13)
Titanocenes of the formula I STR1 in which R1 are cyclopentadienyl? groups and R2 and R3 are aromatic radicals which are substituted in both ortho-positions by fluorine and, in addition, are substituted by a pyrrylalkyl group, amidoalkyl group or imidoalkyl group, are suitable as photoinitiators for the photopolymerization of ethylenically unsaturated compounds.
