The major market for plasticizers is dominated by ptimary plasticizers, phthalate esters, while 10—15% of plasticizers are derived from vegetable oils. The annual plasticizer market is "0.91 MMT (1 million t) and growing. Of the epoxidized vegetable oils, soybean oil is used in "75% of production. Epoxy linseed oil is used in vinyl liners of botde caps and medical mbing, where extraction of plasticizet must be avoided. Epoxy sunflower oil is more compatible with vinyl resin, while epoxy tall oils are used in some plastic products. 

In a collaborative study, a general guideline for separation and quantitation of triglycerides was developed by Firestone [871]. Six different vegetable oils (soybean, almond, sunflower, olive, rapeseed and palm) were characterized using a high carbon load Cjg column (RI detector) and a 50/50 acetone/acetomtrile mobile phase mixture. A presentation of a separation factor versus the number of double bonds... 

To prepare any of the above systems, the formulation chemist must choose an optimum emulsifier system that is suitable for the preparation of the emulsion and maintenance of its long-term physical stability. The oil that may be used as drug carrier has to be nontoxic, e.g. vegetable oils (soybean and safflower), synthetic glycerides (including simulated human fats), and acetoglycerides.

The hydroformylation of vegetable oils (soybean, high oleic safflower, safflower, and linseed) using Rh(CO)2(acac) as the catalyst precursor in the presence of PPhs or (PhOlsP was studied. The ligand (PhO)3P resulted in a lesser reactivity compared to TPP in contrast to the rates of bulky phosphite ligands reported in the literature [16]. 

E. is used for the manufacturing of epoxidized vegetable oils (soybean and linseed oil) and of epoxidized alkyl esters of oleic acid and tall oil fatty acid (- epoxides). 

Green coloration, present in many vegetable oils, poses a particular problem in oil extracted from immature or damaged soybeans. Chlorophyll is the compound responsible for this defect. StmcturaHy, chlorophyll is composed of a porphyrin ring system, in which magnesium is the central metal atom, and a phytol side chain which imparts a hydrophobic character to the stmcture. Conventional bleaching clays are not as effective for removal of chlorophylls as for red pigments, and specialized acid-activated adsorbents or carbon are required. 

BHA and BHT, which are both fat soluble, are effective ia protecting animal fat from oxidation, and are often added duting the rendering process. Propyl gallate is also effective, but it has limited fat solubiUty, and turns bluish black ia the presence of iron. It is typically used as a synergist ia combination with BHA or BHT. TBHQ is most effective against oxidation ia polyunsaturated vegetable oils (qv), and is often used ia soybean oil (19). 

The total commercial lecithin potential if all vegetable oils were degummed worldwide would be 552,000 t (Table 7). Although soybean, sunflower, and rape lecithins are available in the market, the principal commercial interest is only in soybean lecithin. The aimual worldwide production is 130,000 t (Table 8). 

Industrial, ie, nonfood, utilization of vegetable oils is much smaller than food usage. Soybean oil usage in the United States for industrial purposes was ca 2% of total production in 1993. Quantities are given in Table 13 (55). 

Polyunsaturated fatty acids in vegetable oils, particularly finolenic esters in soybean oil, are especially sensitive to oxidation. Even a slight degree of oxidation, commonly referred to as flavor reversion, results in undesirable flavors, eg, beany, grassy, painty, or fishy. Oxidation is controlled by the exclusion of metal contaminants, eg, iron and copper addition of metal inactivators such as citric acid minimum exposure to air, protection from light, and selective hydrogenation to decrease the finolenate content to ca 3% (74). Careful quality control is essential for the production of acceptable edible soybean oil products (75). 

Nonfood Uses. Vegetable oils are utilized in a variety of nonedible applications, but only a few percent of the U.S. soybean oil production is used for such products (see Table 13). Soybean oil is converted into alkyd resins (qv) for protective coatings, plasticizers, dimer acids, surfactants (qv), printing inks, SoyDiesel fuel (methyl esters used to replace petroleum-based diesel fuel) and other products (76). 

Vegetable oils, typically soybean, are important feedstocks for the commercial production of the RRR forms of vitamin E. 

Many similar hydrocarbon duids such as kerosene and other paraffinic and naphthenic mineral oils and vegetable oils such as linseed oil [8001-26-17, com oil, soybean oil [8001-22-7] peanut oil, tall oil [8000-26-4] and castor oil are used as defoamers. Liquid fatty alcohols, acids and esters from other sources and poly(alkylene oxide) derivatives of oils such as ethoxylated rosin oil [68140-17-0] are also used. Organic phosphates (6), such as tributyl phosphate, are valuable defoamers and have particular utiHty in latex paint appHcations. Another important class of hydrocarbon-based defoamer is the acetylenic glycols (7), such as 2,4,7,9-tetramethyl-5-decyne-4,7-diol which are widely used in water-based coatings, agricultural chemicals, and other areas where excellent wetting is needed.

Biodiesel is diesel fuel produced from vegetable oils and other renewable resources. Many different types of oils can he used, including animal fats, used cooking oils, and soybean oil. Biodiesel is miscible with petroleum diesels and can he used in biodiesel-diesel blends. Most often blends are 20 percent biodiesel and 80 percent traditional diesel. Soy diesel can be used neat (100%), hut many other types of biodiesel are too viscous, especially in winter, and must be used in blends to remain fluid. The properties of the fuel will vaiy depending on the raw material used. Typical values for biodiesel are shown in Table 1. 

Phylloquinone (vitamin Kl) is the form of vitamin K synthetized by mainly green leafy vegetables and such also appears in plant oils (soybean, cottonseed, canola, olive). Both are good sources for a daily supply, although the need of such a supply is still under discussion. Table 1 shows some good sources and their content of vitamin Kl. 

Flaky piecrusts used to contain lard, or at least butter. Solid fats are important in baking, as they separate sheets of dough into thin, independent flakes. Traditional solid fats are animal-derived saturated fats, such as lard and butter. Some vegetable fats, such as coconut and palm kernel oils, are solid, but they are more expensive than some liquid vegetable oils like corn oil, cottonseed oil, or soybean oil. These oils come from plants that are used for more than just the oil they provide. Using several different parts of the plant makes growing them more economical. 

It is the last two problems, particularly in urban areas, that are causing most public concern. Most recent research into biodiesel has focused on vegetable oils such as soybean, sunflower, palm and rapeseed. Although animal fats have been considered, their availability in the quantities required have precluded serious utilization.
