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.
