Technologies - 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.
