“…Castor oil is a fatty oil obtained by extracting and refining from the mature seeds of the castor plant (Ricinus communis L.) . Due to high content of ricinoleic acid, − it is used in a variety of applications including medicine, chemicals industry, and other technologies . Alkali fusion is one of the unit processes involved in converting castor oil to chemical intermediates with 8–10 carbon atoms .…”

A green and environmentally friendly route of no thinning agent was designed to prepare sebacic acid. Sodium ricinoleate was selected as the raw material to carry out solid-phase cleavage in a tubular furnace. The reaction parameters including catalyst, ratio of sodium ricinoleate/KOH, reaction time, reaction temperature, and absolute pressure were optimized to obtain a high yield of sebacic acid. A satisfactory yield (70.2%) of sebacic acid was received in the presence of 1% catalyst (Fe 2 O 3 ) by weight (w/w), with 5:4 (w/w) ratio of sodium ricinoleate/KOH at 543 K under the absolute pressure of 0.09 MPa in 60 min. Sebacic acid was identified by gas chromatography analysis, and the purity (98.1%) of the product was further assessed by its melting point (306.3 K). Alkaline enhancement generates a better cracking effect. The yield of sebacic acid can be improved by a certain absolute pressure as a result of avoiding oxidation of sodium ricinoleate as well as reducing the residence time of hydrogen.

“…Dehydrated castor oil (DCO) as a kind of drying oil is one of these derivatives. DCO is widely applied to the surface coating industry because of its superior waterproofing ability, good flexibility, rapid drying, outstanding color retention, etc , . DCO is obtained by the catalytic dehydration of castor oil, and the key component of castor oil is ricinoleic acid , …”

n-Dodecyltriethoxysilane (DTEOS) modified NaHSO 4 / MCM-41 catalysts (silanized catalysts) were synthesized by different impregnation sequences and evaluated in the liquid-phase dehydration of castor oil. The samples were evaluated by X-ray diffraction, nitrogen adsorption-desorption, SEM, TEM, FT-IR spectroscopy, XPS, 29 Si MAS NMR spectroscopy, contact angle measurements, NH 3 -TPD, and pyridine-FT-IR spectroscopy. The analyses demonstrated that silanization enhanced the hydrophobicity of the catalysts, and the impregna-* Prof. Dr. J.-F. Ding E-Mail : ycitjfding@sina.com [a] School of Chemical Engineering

“…Following the development of the functionality concept,5 various forms of modifications (e.g., the incorporation of a drying oil into a polyester system to give alkyd resins, thermal polymerization, and the modification of an oil with monomers possessing double bonds) have been introduced to fulfill these stringent requirements 6–8. Castor oil and lesquerella oil, which are naturally nondrying, are now transformed into drying oils through modification by dehydration 9–12. This development in coating technology has given rise to modern‐day hard, oil‐soluble synthetic resins with performance characteristics far superior to those of natural resins.…”

Rubber seed oil (RSO) was modified with different amounts of maleic anhydride, and RSO alkyds (50% oil length) were modified to various extents by the incorporation of different amounts of maleic anhydride and fumaric acid. All the resins were evaluated as water-reducible binders. Modification with maleic anhydride increased the acid and saponification values of RSO but reduced the iodine value. RSO modified with maleic anhydride exhibited lower amounts of volatile organic compounds (Ͻ20 g/L) than the corresponding RSO alkyds (34 -87 g/L). The alkyd samples were superior to the modified RSO in chemical resistance.
