Acetophenone CAS 98-86-2


Acetophenone is the simplest aromatic ketone in which the aromatic nucleus (benzene ring) is directly attached to the carbonyl group. It exists in the free state in the essential oils of some plants. Pure product is colorless crystal. Commercially available products are mostly light yellow oily liquid. Has an aroma like hawthorn. Slightly soluble in water, soluble in a variety of organic solvents, can be volatile with the vapor. Molecular structure of acetophenone: methyl C-atoms are bonded by sp3 hybridized orbitals, benzene ring and carbonyl C-atoms are bonded by sp2 hybridized orbitals. Acetophenone can occur carbonyl addition reaction, α-active hydrogen reaction, but also can occur on the benzene ring electrophilic substitution reaction, mainly generated meso products. Acetophenone can be produced by the reaction of benzene with acetyl chloride, acetic anhydride or acetic acid catalyzed by aluminum trichloride. In addition, acetophenone is a by-product of the catalytic oxidation of ethylbenzene to styrene. Acetophenone is mainly used as a raw material for pharmaceuticals and other organic synthesis, and is also used in the preparation of fragrances. Used in the production of soap and cigarettes, can also be used as a solvent for cellulose ether, cellulose esters and resins and plastic plasticizers, hypnotic. Nowadays, acetophenone is mostly obtained as a by-product of the oxidation of isopropylbenzene to make phenol and acetone, and it can also be made from benzene by acetyl chloride acetylation.

1.Performance and use

When Acetophenone is used as a solvent, it has the characteristics of high boiling point, stability and pleasant odor. Solubility is similar to cyclohexanone, and it can dissolve nitrocellulose, cellulose acetate, vinyl resin, coumarone resin, alkyd resin, glycerol alkyd resin, etc. It is often mixed with ethanol, ketone, ester in Chemicalbook and other solvents. It is often mixed with ethanol, ketone, ester and other solvents. When used as spice, it is the blending raw material of hawthorn, mimosa, lilac and other flavors, and is widely used in soap flavors and tobacco flavors. It is used to synthesize phenylglycolic acid, α-phenylindole, isobutylphenylpropionic acid and so on.

Used as raw material for manufacturing spices and medicine

Used as extractant. Catalyst for olefin polymerization. Plasticizer. Photosensitizer. Organic synthesis.
