B. Ricinoleic Acid Remove the hexane layer obtained in Identification Test A, extract again with 5 mL of hexane, and remove the hexane layer. The fatty acids thus extracted have a hydroxyl value corresponding to that of castor oil fatty acids (about 150 to 170). 

Polyglycerol Polyricinoleic Acid is prepared by esterification of polyglycerol with condensed castor oil fatty acids. The castor oil fatty acids are mainly composed of 80% to 90% ricinoleic acid. It is a clear, light brown, viscous liquid. It is soluble in ether, in hydrocarbons, and in halogenated hydrocarbons. It is insoluble in water and in alcohol.

Unsaturated poly(ester-imide) resins are known having imide structures at the end of the molecule or in the backbone. Chain termination by imide is frequently done with the tetrahydrophthalic anhydride (23) aminoethanol (9) reaction product [10,201-204]. In the synthesis of these resins, maleic anhydride is used. It is cheap and a world-wide available raw material, having the advantage of generating per mol only one mol of distillate. Patents are known where fumar-ic acid is claimed, e.g., in [205], but it is probably not frequently used in industrial processes. Anyway, under the conditions of the esterification reaction, a part of the maleate is isomerised into the fumarate [206]. To get materials with good heat resistance the use of THEIC is claimed for branching the unsaturated poly(ester-imide) resins [202]. Flexibility and heat resistance are improved when fatty acids, e.g., castor oil fatty acid [205,207], are build into the macromolecule. 

Epoxy resins have provided excellent corrosion resistant primers for appliances. These can be made from epoxy resins esterified with dehydrated castor oil fatty acids and cured with melamine. Excellent detergent resistance and corrosion resistance are obtained from this type of resin system.

Epoxy esters can also be made water-reducible by reacting maleic anhydride (2,5-furandione) [108-31-6] with epoxy esters prepared from dehydrated castor oil fatty acids. Addition of a tertiary amine opens the anhydride to give amine salts. Like other water-reducible resins, these resins are not soluble in water, but form a dispersion of resin aggregates swollen with water and solvent in an aqueous continuous phase. They are used in baking primers and primer-surfacers. 

Castor oil fatty acids have one double bond per molecule, whereas hydrogenated castor oil fatty acids are saturated consequently, the oils, or alkyds derived from them, are not film forming under autooxidation conditions. However, alkyds prepared from these oils are widely used as polymeric plasticizers for other filmforming resins the two most important types are cellulose nitrate and melamine-formaldehyde condensates. 

Epoxy resins may be converted to coatings with good resistance to mild acid and alkaline environments by esterification of the expoxide and hydroxyl groups with dehydrated castor oil fatty acids. Linseed or soybean oil acid may also be used.
