- Acetophenone is a
crystalline ketone that is used as a solvent for cellulose ethers and
esters in the manufacture of alcohol-soluble resins. It can be found
naturally in apple, cheese, apricot, banana, beef and cauliflower.
- This chemical may be
obtained by the dry distillation of a mixture of the calcium salts of
acetic and benzoic acids. Currently 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.
- Complex metal hydrides,
such as sodium borohydride, are the most commonly used reducing agents
in synthetic chemistry. In this experiment, acetophenone was reduced by
sodium borohydride in the presence of ethanol to form 1-phenylethanol.
The goal was to achieve as close to 100% yield as possible for
1-phenylethanol once its synthesis had been confirmed. Its presence was
confirmed by the chromic acid test, which oxidized the product back to
acetophenone.
- This chemical may be
obtained by the dry distillation of a mixture of the calcium salts of
acetic and benzoic acids. Currently 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.
- The percent yield was
found to be 47.3% for 1-phenylethanol, but this could have been improved
if more care been taken when performing the experimental rocedures. The
1H NMR, 13C NMR, and IR spectra for both acetophenone and
1-phenylethanol were predicted and compared. It was determined that the
major difference in the spectra came from the deshielding effect of the
carbonyl group present in acetophenone.
- Solvents are used as
additives in industrial production e.g. in the adhesive, paint, varnish
and household cleaning agent industries. They are also used as
components in pharmaceuticals, cosmetics, cleaning and paint stripping
agents. Therefore solvents are contained in many everyday products and
we come into contact with them consciously or unconsciously almost every
day.
- 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. Some 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.
- 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.
