“…Therefore, the thermal treatment of esterified castor oil derivatives can be considered as an additional approach for the synthesis of dehydrated castor oil, yielding similar products as depicted in Fig. 6 [51][52][53]. Dehydrated castor oil is well known for its non-yellowing and outstanding color retention characteristics; it has better drying properties than linseed oil and its water and alkali resistance can be almost as good as for tung oil [54].…”

Castor oil is, as many other plant oils, a very valuable renewable resource for the chemical industry. This review article provides an overview on this specialty oil, covering its production and properties. More importantly, the preparation, properties and major application possibilities of chemical derivatives of castor oil are highlighted. Our discussion focuses on application possibilities of castor oil and its derivatives for the synthesis of renewable monomers and polymers. An overview of recent developments in this field is provided and selected examples are discussed in detail, including the preparation and characterization of castor oil-derived polyurethanes, polyesters and polyamides.

“…For instance, in the manufacture of non-drying alkyd resin, castor oil is esterified with phthalic anhydride (3). Fatty acid esters of castor oil, as well as acetylated castor oil, were reported previously as the starting materials for the preparation of dehydrated castor oil (4,5). Additionally, secondary esters of castor oil formed with drying oil fatty acids were also studied in order to obtain a material with drying oil properties (6).…”

In this study, esterification of castor oil with oleic acid was investigated in view of the reaction kinetics under various conditions. Potassium hydroxide, p-toluenesulfonic acid and tin chloride (SnCI22H20) were used as catalysts. Reaction was carried out at 200~ 225~ and 250~ by using equivalent proportions of the reactants. For tin chloride, experimental data fitted the second-order rate equation, while for the other catalysts the obtained data fitted the third-order rate equation.

“…Many catalysts are reported for dehydration of castor oil, the most widely used being sulfuric acid, sodium bisulfate, and acid-activated clays (8)(9)(10)(11)(12)(13)(14). An additional way to produce DCO is to split the secondary esters of castor oil (15)(16)(17)(18). Our laboratory has studied the kinetics of splitting secondary esters of castor oil with fatty acids (19).…”

The dehydration reaction kinetics of castor oil was investigated with sodium bisulfate-sodium bisulfite mixture (SB-SB) or p-toluenesulfonic acid as catalyst. Reactions were carried out at 210, 220, and 230°C, and a kinetic model was determined for each case. The reactions with SB-SB catalyst at 210 and 220°C and with p-toluenesulfonic acid at 210°C followed second-order kinetics. A first-order rate equation showed the best fit to the experimental data for the reaction with SB-SB at 230°C. p-Toluenesulfonic acid-catalyzed reactions at 220 and 230°C were also first-order reactions. Additionally, some mathematical equations were derived between iodine value, refractive index, viscosity, and reaction time. JAOCS 74, 409-412 (1997).
