1-hydroxycyclohexyl phenyl ketone has another name called photoinitiator 184 and (1-hydroxycyclohexyl)phenyl-methanon which is one of the most inportant freeradical photoinitiator in chemcial industry. Photoinitiator can absorb radiation energy ,after chemical reaction produce reactive intermediates materials which obtain initiator polymerizing power and this materials is the main ingredient in any UV system
The photoinitiator 1-hydroxycyclohexyl phenyl ketone was prepared using cyclohexanecarboxylic acid as raw materials through acyl chloridation,Frield-Crafts reaction,halogenation and hydrolysis.PCl 3 was selected as acyl chloridation agent in the new process and the molar ratio of CCA to PCl 3 was 1¡Ã0.43.The reaction proceeded at 75¡æ for 2.5 h.The yield was 94.6%.Bromine was used in halogenation at 70¡æ for 0.25 h and the yield was 98%.Compared with the traditional procedure,the method metioned in this article not only reduced the emission of hazardous gas,but also shortened the reaction period.The total yield was 70%.
In additional, Jinchemical adopt the new improving technology and specilized catalyst to produce photoinitiator 184 which is purer and brighter and higher assay of 99.3%min steadily. We have established relevant operational procedures and description of this product storage ,package and transportation and we promise every customer will receive high-quality products and use the highest quality raw materials into the next production chain. |
