General
- Acetophenone is
a crystalline ketone that is used as a solvent for cellulose ethers
and esters in the manufacture of alcohol-soluble resins.
- These in turn
are used in perfume. Acetophenone is used to create fragrances that
resemble almond, cherry, honeysuckle, jasmine, and strawberry. It is
used in chewing gum. It can be found naturally in apple, cheese,
apricot, banana, beef and cauliflower.
Process
- This chemical
may be obtained by the dry distillation of a mixture of the calcium
salts of acetic and benzoic acids.
- acetophenone
mainly comes as a by-product of the phenol-acetone synthesis in the
cumene oxidation process. At one time it was used as a hypnotic under
the name of hypnone.
- Acetophenone is
also extracted from the production stream and marketed in a commercial
quality of 98 % and 99 % purity. It is a basic raw material in
hydrocarbon resins for the production of adhesives and printing inks.
Acetophenone is also a precursor to certain agrochemicals. A very
special application of Acetophenone is its use in the production
of synthetic musk for the perfume industry.
Market
- Some solvents
have however proven to be harmful or are suspected of being harmful.
This has led to a flood of regulations for the protection of health
and the environment which have been put into practice by industry.
- solvents are now
completely prohibited, others are limited in their application areas
and many substances are now being recycled and re-used. The vast
quantity of legal measures has brought about major changes in the
solvent market.
