Dichloromethane is used as a noncombustible solvent and extractant for oils, fats, waxes, fish oil, etc. from industrial and animal products, as well as caffeine, hops, castor oil, cocoa butter, and ethereal oils from substances of plant origin. It is used in the deparaffination of petroleum and the azeotropic dewatering of solvents. Dichloromethane is a constituent of paint-removal pastes and baths, but is increasingly being replaced by aqueous systems. It is used as a solvent in the production of cellulose-acetate-based or cellulose-acetobutyrate-based films and is employed industrially in the leather, metal, rubber, adhesives, and plastics industries. 

Today palm oil is widely used in food applicahons and preferred for frying and baking applications because of its good oxidative stability and high solid fat content. Palm oil contains about 50% saturated (42 8% palmitic and 4-5% stearic acids) and 50% unsaturated fatty acids (37-41% linoleic and 9-11% linolenic acids). The fatty acid composition of palm kernel oil resembles that of the coconut oil rather than that of palm oil. Palm kernel oil is rich in lauric (about 48%), myristic (16%) and oleic (15%) acids. Both palm oil and pahn kernel oil are commercially separated into stearin (solid) and olein (liquid) fractions for special applications. The stearin fraction obtained from palm kernel can be used as a cocoa butter substitute. The olein fraction is used in baked goods and soap manufacturing. Imitation palm-oil-based cheese, hand and body lotion, fatty acid methyl esters for use as fuel or solvent, and epoxidized pahn oil to produce plasticizers and stabilizers for conventional polyvinyl chloride plastics are some of the other products that are produced from palm oil (Basiron, 2005).
