Castor oil derivatives

For the most part, additives control the appHcation or theological properties of a paint. These additives include materials for latex paints such as hydroxyethylceUulose, hydrophobicaHy modified alkah-soluble emulsions, and hydrophobicaHy modified ethylene oxide urethanes. Solvent-based alkyd paints typically use castor oil derivatives and attapulgite and bentonite clays. The volume soHds of a paint is an equally important physical property affecting the apphcation and theological properties. Without adequate volume soHds, the desired appHcation and theological properties may be impossible to achieve, no matter how much or many additives are incorporated into the paint. 

Castor oil, derived from the beans of Acinus communis is converted to a drying oil by heating with catalysts to yield dehydrated castor oil. 

By comparison, the synthesis of SIN s involved a castor oil derived crosslinked elastomer and crosslinked polystyrene as... 

A 100% natural polymer based entirely on agricultural products, the polyester elastomer obtained by reacting castor oil with a castor oil derivative, sebacic acid, was the basis for the synthesis of SIN s. 

Based on castor oil derived elastomers and crosslinked polystyrene, a simultaneous mode of polymerization can be successfully employed to synthesize prototype engineering materials such as tough, impact resistant plastics and reinforced elastomers. 

Hypersensitivity reactions A few patients receiving the injection have experienced anaphylactic reactions. Although the exact cause of these reactions is not known, other drugs with castor oil derivatives in the formulation have been associated with anaphylaxis in a small percentage of patients. 

Much work has been done on the incorporation of castor oil into polyurethane formulations, including flexible foams [64], rigid foams [65], and elastomers [66]. Castor oil derivatives have also been investigated, by the isolation of methyl ricinoleate from castor oil, in a fashion similar to that used for the preparation of biodiesel. The methyl ricinoleate is then transesterified to a synthetic triol, and the chain simultaneously extended by homo-polymerization to provide polyols of 1,000, 000 molecular weight. Polyurethane elastomers were then prepared by reaction with MDl. It was determined that lower hardness and tensile/elongation properties could be related to the formation of cyclization products that are common to polyester polyols, or could be due to monomer dehydration, which is a known side reaction of ricinoleic acid [67]. Both side reactions limit the growth of polyol molecular weight.

Another interesting castor oil-derived platform chemical is 10-undecenal, which is at the same time a challenging substrate for olefin metathesis. For the SM of 10-undecenal, Dixneuf et al. modified C3 and C5 by insertion of SnCl2 into one Ru-Cl bond [48]. Modification of C3 led to a binuclear complex, which showed a conversion of 70% at a catalyst loading of 0.33 mol%. On the other hand, both the modified and unmodified C5 gave conversions over 70% with catalyst loadings of 1.25 mol%, but also led to formation of a high amount of by-products.
