ABSTRACT

Fats and oils are an important part of the diet, providing caloric content and essential fatty acids to the consumer. However, fats and oils are also important feedstocks for the chemical industry. For untold centuries, they have served as a source of soaps, §ammable fuel for illumination, lubricants, and drying oils for paints and coatings, to name the more prominent applications. The discovery of petroleum followed by expanded production, re­ning, and chemical conversion processes provided cheaper and more abundant substitutes for many of these applications. The relatively recent focus on increasing the use of renewable resources to manufacture products has led to a resurgence of nonpetroleum products to replace those derived from petroleum. This has resulted in increased interest in developing oils and fats with properties enhanced for chemical feedstock use. With the
