Chemical modification of sunflower waste cooking oil for biolubricant production through epoxidation reaction

There are increasing concerns and growing regulations over contamination and environmental pollution. One of the major concerns is the pollution caused by mineral oils. As the world oil reserves are dwindling the pressures for finding alternative replacements are increasing. Vegetable oils are a bio...
