Soya bean oil

Commercial lecithin is a mixture of phos-phatides and glycerides obtained in the manufacture of soya bean oil. It gives a thick yellow emulsion with water, and is widely used in the food and other industries. 

Most of the trichloroethylene produced is used for metal degreasing. Other important uses are in the scouring of wool and as an extractive solvent, e.g. for olive and soya bean oils. Minor uses are as a heat transfer medium, anaesthetic, insecticide and fumigant, paint remover and fire extinguisher. 

Although the black inks are predominantly based on mineral oil, colors are almost entirely formulated with a soya bean oil vehicle. The superior printabHity of colors and economics of blacks guide the selection of product types by the market. Recently developed low mb blacks offer smudge-resistant print. Their share of the market is growing rapidly. The low mb characteristics of these inks are produced through the use of low stmcture carbon black. The addition of resin further enhances the smudge resistance but imposes a premium price. 

Inks. Basic raw materials for letterpress inks, such as mineral oils, soya bean oil, resins, and pigments, are essentiaHy the same as those used in web offset inks. Inks are tinctoriaHy weak, relatively fluid, and their low and high shear viscosities are low. 

These resins are produeed by reacting a polyhydric alcohol, usually glycerol, with a polybasic acid, usually phthalic acid and the fatty acids of various oils such as linseed oil, soya bean oil and tung oil. These oils are triglycerides of the type shown in Figure 25.30. R], R2 and R3 usually contain unsaturated groupings. The alkyd resins would thus have structural units, such as is shown in Figure 25.31. 

The number of epoxy groups per molecule will vary but for modified soya bean oils there are an average of about four whereas there are about six for epoxidised linseed oils.

The use of IR spectroscopy for the identification of plasticisers was discussed in Section 2.4. Separation by SEC is often required to confirm the use of polymeric plasticisers. Most of the common plasticisers for plastic materials can be detected and analysed either by GC-MS or LC-MS. Complex plasticisers such as epoxidised soya bean oil can be fully characterised by LC-MS using chromatography in hexane/propionitrile with detection by positive ion APCI.

Azomethine metal complex pigments replace the metal with tin stabilizers, resulting in a change in shade. In the case of manganese-laked pigments trouble can also be expected in the presence of epoxy compounds. Pigment preparations based on epoxidized soya bean oil are normally used instead of diisodecyl phthalate pastes in the automotive sector e.g. for coloring PVC roofs etc.

Certain vegetable and animal fats have been used as dampproofers and again emulsions or pastes are preferred and typical formulations are given in Table 4.3 [10]. The fat can be white grease, tallow or soya bean oil and although they all produce hydrophobic concrete, different effects on compressive strength are obtained.
