Application of 1-Hydroxycyclohexyl Phenyl Ketone
Photoinitiator 184 is widely used in coatings, inks, electronics, optical fibers, adhesives, printing and other fields, and shows strong vitality. Examples of its application are as follows:
The UV-curable coating is composed of a primer and a topcoat, wherein the components of the primer and the topcoat are respectively in proportion by weight: primer: epoxy acrylate 20-40, urethane acrylate 10-20, 1 ,6-Hexanediol diacrylate 2~6, Trimethylolpropane triacrylate 30~40, 1-Hydroxycyclohexyl phenyl ketone 1~5, benzil dimethyl ketal 3~8, Polyether-modified polydimethylsiloxane 0.2-1; topcoat: acrylate-modified solvent-containing oligomer 40-60, trimethylolpropane triacrylate 30-50, 1-hydroxycyclohexylbenzene methyl ketone 5~10, 2,4,6-trimethylbenzoyl-diphenylphosphine oxide 1~3, polyether modified polydimethylsiloxane 0.5~2, trifunctional ester 1~ 3. Nano-grade color essence 1-3. The preparation method is:
- Prepare primer: add epoxy acrylate, urethane acrylate, 1,6-hexanediol diacrylate, trimethylolpropane triacrylate, 1-hydroxycyclohexylbenzene according to the component ratio of above-mentioned primer methyl ketone, benzil dimethyl ketal, polyether-modified polydimethylsiloxane, disperse and stir at high speed, control the temperature at 20-25°C, and stir at 800-1000 r/min for 0.5h-1h After mixing evenly, filter and remove slag to obtain the finished primer.
- Preparation of topcoat: add acrylate modified solvent-containing oligomer, trimethylolpropane triacrylate, 1-hydroxycyclohexyl phenyl ketone, 2,4,6 —Trimethylbenzoyl-diphenylphosphine oxide, polyether-modified polydimethylsiloxane, trifunctional acid ester, and nano-chromatin were dispersed and stirred at high speed, and the temperature was controlled at 20-25°C, and the temperature was controlled at 800°C. ~1000 r/min stirring for 0.5h~1h, then filter and remove slag to get the finished paint.
By weight, including 25%-50% bisphenol A epoxy acrylate, 25%-50% trimethylolpropane triacrylate, 18%-33% tetrahydrofuran acrylate, 1%-5% 1-hydroxyl ring Hexyl phenyl ketone and each component are prepared according to the above weight ratio. -Hydroxycyclohexyl phenyl ketone is successively added to the mechanically stirred reactor, and while adding, stirring is performed for 2 hours to 3 hours, and finally the discharging valve is controlled to slowly discharge, measure and pack, and the present invention is easy to prepare, Low cost, high mold release, high leveling, high hardness, yellowing resistance, can meet the requirements of high-performance reflective film produced by UV coating method.
The matte antistatic coating material is used for release paper, and the matte antistatic coating material is composed of the following components by mass percentage: 2% of silica particles, acrylic polyol with an average molecular weight of 500-2000 28%, polyoxyalkylene series polyol resin with average molecular weight of 200~2500 36%, polyethylene glycol 20%, cyclomethicone 4%, 1-hydroxycyclohexyl phenyl ketone – photoinitiator 184 is 10%; the particle size of the silica particles is a particle size distribution determined by a laser diffraction scattering method with a particle size in the range of 0.1-2 μm and 1.5-5 μm, respectively, with peaks and an average particle diameter of 4 μm or less.

Preparation of 1-Hydroxycyclohexyl Phenyl Ketone
The specific method of the photoinitiator 184 includes the following steps:
- Cyclohexanecarbonyl chloride carries out electrophilic substitution reaction with benzene under Lewis acid catalysis to obtain only cyclohexyl phenyl ketone.
- Cyclohexyl phenyl ketone reacts with hydrogen peroxide and hydrochloric acid solution under the effect of catalyst to obtain 1-chlorocyclohexyl phenyl ketone.
- The chlorinated intermediate undergoes hydrolysis reaction with aqueous sodium hydroxide solution under the action of a catalyst to obtain 1-hydroxycyclohexyl phenyl ketone.
Utilizing hydrogen chloride in the by-product hydrochloric acid in the process of synthesizing alkyl ketones, in hydrogen peroxide and organic solvent systems, chlorination and hydrolysis are carried out with L potassium molecular sieve catalyst to form α-hydroxy ketones. This new synthesis method has the following advantages: The raw materials are cheap and easy to obtain, safe and environmentally friendly, and the hydrogen chloride generated during the electrophilic substitution reaction of the acid chloride under the catalysis of Lewis acid is fully utilized, and the hydrogen chloride is recycled to reduce the discharge of waste acid water, and is environmentally friendly. The selective chlorination and hydrolysis are completed in the same kettle, the operation is simple, the loss is small, and the yield is high.

- Friedel-Crafts reaction: add benzene and catalyst aluminum trichloride into the reaction kettle, cool down to 5-10 ℃, dropwise add the cyclohexanecarbonyl chloride obtained in step (1), benzene, aluminum trichloride and cyclohexane The weight ratio of hexanoyl chloride is 9:2.9-3.1:3.16-3.36, and the temperature is 15±2°C for at least 2.5 hours to obtain a complex of cyclohexyl phenyl ketone and aluminum trichloride;
- Hydrolysis reaction: add an appropriate amount of dilute hydrochloric acid with a mass concentration of 1.5-2.5% into the complex, stir to separate layers, remove the aqueous layer containing aluminum trichloride, and then add an appropriate amount of water to wash the acid until pH>5 Finish, finally remove unreacted raw material benzene by distillation, obtain cyclohexyl phenyl ketone;
- Chlorination reaction: add cyclohexyl phenyl ketone into the chlorination kettle, heat up to 60±2°C, then feed chlorine gas, and the reaction ends to obtain 1-chlorocyclohexyl phenyl ketone;
- Alkali hydrolysis reaction: add 1-chlorocyclohexyl phenyl ketone into the liquid caustic soda at a weight ratio of 1:0.95-1.10, stir until the reaction ends, then add toluene for extraction, separate the water phase, desolvate, and recover Toluene to obtain crude 1-hydroxycyclohexyl benzophenone;
- Refining: put the crude 1-hydroxycyclohexyl benzophenone into the rectification kettle, rectify the product under the reduced pressure of the Roots pump, and collect the fractions; put the rectified product into the crystallization kettle, and then use The petroleum ether is dissolved and recrystallized, and then centrifuged. The distilled mother liquor is distilled out of the solvent petroleum ether for reuse. After the wet product is dried, the finished product 1-hydroxycyclohexyl benzophenone is obtained.
