Diethyl Phenyl Acetamide (DEPA)
Introduction
A premier technology providing institution
for indeginously developed technologies is offering technology
for diethyl phenyl acetamide (DEPA). Diethyl Ethyl Acetamide
is a multi-insect repellent. It is effective against mosquitoes,
leaches and other blood sucking organisms. It is found to
be much more superior and effective as compared to the commonly
used mosquito repellents like Di-methyl phthalate. DEPA can
be used in the form of cream or as a spray, liquid or aerosol.
Process
The process comprises of reacting the aryl acetic acid with
dialkyl amine in presence of catalyst in an autoclave at specified
temperature and pressure for a specified period of time, distilling
out the excess amine, dissolving the residue in ether, washed
with dilute hydrochloric acid and then with water, sodium
bicarbonate and finally with water and drying over magnesium
sulphate. The solution after evaporation of solvent ether
is distilled under reduced pressure to provide dialkyl aryl
acetamide in 80-100% yield. Acidic effluents is neutralised
with caustic soda.
Salient features:
As compared to other insect repellents
the product, is very effective against blood sucking organisms,
mosquitoes files and leaches etc. Presently several types
of mosquito repellents like mosquito coils, liquid spray,
aerosols, mosquito mats, electric liquid, power chock, etc.
are available in the market. But all these products are not
effective in open space.
