What is Acetophenone?
Acetophenone, boiling point( °C)202.3, relative viscosity( water = 1)1.03( 20 °C), relative vapor viscosity( air = 1)4.14, is the simplest sweet ketone, of which the sweet nexus( benzene ring) directly attached to the carbonyl. It exists in the essential canvases of some shops in a free state. The pure product is tintless demitasse. Commercially available products are substantially light unheroic unctuous liquid. Has a hawthorn- suchlike aroma. Slightly answerable in water, fluently answerable in colorful organic detergents, and can volatile with brume.
Molecular structure of acetophenone the methyl C snippet is clicked by sp3 mongrel orbital, and the benzene ring and carbonyl C snippet are clicked by sp2 mongrel orbital. Acetophenone can suffer carbonyl addition response, α-active hydrogen response, and electrophilic negotiation response on the window ring, substantially generating meta-position products. Acetophenone can be prepared by replying benzene with acetyl chloride, acetic anhydride or acetic acid under the catalysis of aluminum trichloride. In addition, acetophenone is a by- product during the catalytic oxidation of ethylbenzene to styrene. Acetophenone is substantially used as a raw material for medicinals and other organic conflation, and also for the medication of spices. It’s used to make cleaner and cigarettes, and can also be used as a detergent for cellulose ethers, cellulose esters, and resins, as Well as a plasticizer for plastics. It has narcotic parcels. At present, acetophenone is substantially attained as by- products of phenol and acetone by oxidation of cumene, and it can also be attained by acetylation of benzene with acetyl chloride.
When used as a detergent, it has the characteristics of high boiling point, stability and affable smell. The solubility is analogous to that of cyclohexanone, which can dissolve nitrocellulose; cellulose acetate; vinyl resin; coumarone resin; alkyd resin; glycerol alkyd resin, etc. frequently with ethanol; Ketone; Esters and other detergents mixed. When used as spices, it’s the blending raw material of hawthorn; mimosa; lilac and other flavors, and is extensively used in cleaner flavors and tobacco flavors. Used in the conflation of mandelic acid; α- phenylindole; ibuprofen,etc., and also used as a plasticizer for plastics.
Naturally occurring: present in milk, cheese, cocoa, raspberry, peas, and Sri Lankan cinnamon oil.
Sensory profile: Almond-like benzaldehyde-like, sweet nutty, fruity after dilution.
Suggested application: It can be used to prepare food flavors such as cherries, nuts, tomatoes, strawberries, apricots, etc. It can also be used in tobacco flavors.

Application of Acetophenone
Acetophenone can be used to prepare α-fluoroacetophenone. The importance of fluorinated compounds in the development of new pharmaceuticals, pesticides and functional materials is well recognized by the scientific and industrial communities. The method for preparing α-fluoro-p-methylacetophenone with p-methylacetophenone is as follows:
Take 1mmol choline chloride and 1mmol TsOH in a round bottom flask, heat to form a eutectic, and slowly cool to room temperature. Add 3ml of acetonitrile, add 2mmol of p-methylacetophenone, slowly add 1.1mmol of DCDMH, react for 3 hours, and continue to stir for 1 hour. After adding 5 mmol of zinc fluoride, 6 mmol of tetramethylammonium fluoride was added in batches, and the reaction was continued for 8 hours at 50° C. After filtering, the filtrate was rotary evaporated to remove the solvent, then added 20ml of 5% dilute hydrochloric acid, extracted with 20ml of dichloromethane, washed twice with 20ml of water until neutral. MgSO4 was dried, and the solvent was removed by rotary evaporation to obtain a crude product, which was separated and purified by column chromatography to obtain the product α-fluoro-p-methylacetophenone.
