Soya fatty acids

Monobasic Acids. The overwhelming majority of moaobasic acids used ia alkyd resias are long-chain fatty acids of aatural occurreace. They may be used ia the form of oil or free fatty acids (see Fats and fatty oils). Free fatty acids are usually available and classified by their origin, viz, soya fatty acids, linseed fatty acids, coconut fatty acids, etc. Fats and oils commonly used ia alkyd resias are givea ia Table 4. 

Because the total polyol is to be equimolar to PA, the glycerol from the soya oil must therefore be 0.375 mol, which gives 1.125 mol of soya fatty acids. Summarizing thus far ...

The basic reaction of alkyds is esterification. A difunctional acid such as phthalic anhydride, a monofunctional fatty acid such as soya fatty acid, and a polyfunctional alcohol such as glycerine or pentaerythitol are reacted together under conditions of heat, catalyst, and elimination of water. Conventional esterification catalysts are effective. 

Natural source descriptions are used to describe alkyl species that are derived from a particular animal or vegetable source, i.e., coco alcohols, soya fatty acids, and tallow amines. The EPA and CAS currently regard source-derived registrations as the most specific, very narrowly based, description of fatty acid products. Source-based descriptions are interpreted as substances which are solely derived from the named source. A more chemically detailed description is not ordinarily interchangeable with a source-derived description even if the chemically detailed description is totally accurate because sources other than that named could be used. However, a chemically detailed description could be changed to a source-derived description if the substance was derived from the source described. 

About 11% are processed to yield soya fatty acid, amines, amides, esters, soaps and other oleochemical derivatives.

Amoco HS-7 is a soya fatty acid, trimethylol propane, neopentyl glycol, isophthalic acid alkyd of acid value 6. The formulation is available from Amoco Chemicals (publication GTSR-75B). Cymel303 is a hexamethoxy methyl melamine resin at 100% solids supplied by Cytec. 

When f = 1, p = 100%, and the equation predicts that no gelation occurs when bifunctional compounds are used. Therefore, alkyd chemists tend to use formulations in which / = approximately 2.0 in order to get alkyd resins which will not gel during manufacture. In other words, the molar equivalents of hydroxyl should equal the molar equivalents of carboxyl groups. In actual practice an excess of hydroxyl equivalents is used to give specific properties, especially in baking coatings. For example, a typical alkyd with 20% excess of hydroxyl and a functionality of 2 is prepared from phthalic anhydride, 1.0 mole (2 equivalents) glycerol, 1.0 mole (3 equivalents) and soya fatty acids (soyal oil), 0.5 mole (1.5 equivalents).
