245		0	_aDevelopment of non-edible oils for use in the Nigerian surface coating industry with particular reference to rubber (Hevea brasiliensis) seed oil for manufacture of air drying oil modified alkyds
520			_aThe utilization of edible oils for industrial purposes should be discontinued and discouraged in Nigeria for two obvious and important reasons: i. Short supplies leading to competition with food. ii. Scarce foreign exchange to import these oils. There is, therefore, urgent need to investigate and develope available non-ebible oils for use in the manufacture of Alkyd Resins. Rubber seed oil has been reported to have as its constituents, 30-35;of Linoleic Acid and 21-24;of linolenic acid, giving a property similar to a semi-drying oil such as Soya Bean Oil. Rubber seed oil, when alkali refined, could therefore be used in the preparation of air-drying oil modified alkyd. Air-drying alkyds occupy an important place in the paint industry and the demand is estimated at about 16, 000 tons (50;solid resin) of which approximately 2,500 tons of vegetable oil would be needed for the poly-condensation reaction. Rubber seed oil could, therefore, be adopted as a total or partial replacement for the currently used traditional edible oils such as Soya Bean oil or Linseed oil in this industry. Another indgenous oil is Tobacco seed oil derived from the seeds of Nicotiana tabacum, which has the required properties of semi-drying oils and is available locally in massive quantities. The potential of this oils should also be investigated and developed.
