Description :
The availability and price of crude petroleum is challenging Indian economy seriously.
We must think of some basic solutions to this problem. Our industrial and household
products like detergents, paints, printing Inks, lubricants, cosmetics are all based on
crude petroleum. Our laboratory has taken a serious note of this situation and we have
made scientific efforts to replace petroleum products with products of vegetable origin.
In this paper, concentrating on one modification of vegetable oil by the process of
malenization. In fact it is quite simple to modify vegetable oils like linseed oil, and
coconut oil by treatment with Maleic anhydride. The conditions for the preparation of
malenized oil in terms of mole ratio of reactants, temperature and catalyst have been
synthesized. The malenization of oils has also been tried by microwave synthesis. The
results are promising and the reactions can be completed in 3 to 5 minutes. These
malenised oils have been compared with standard active materials like linear Alkyl
benzene sulphonate and Alpha olefin sulphonate. The malenized oils can successfully
replace Acid slurry and Alpha olefin sulphonate to the extent of fifty to seventy percent.
Liquid detergents based on malenized oils have been formulated and analyzed for
various characteristics like foaming, detergency and stain removing. Malenized oils
appear to be a promising substitute for crude petroleum based active materials.
