Ricinoleic acid-based biopolymers

Journal of Biomedical Materials Research, 1999
Polyanhydrides synthesized from pure ricinoleic acid half-esters with maleic and succinic anhydrides possess desired physicochemical and mechanical properties for use as drug carriers. Ricinoleic acid maleate or succinate diacid half-esters were prepared from the reaction of crude ricinoleic acid (85% content) with succinic or maleic anhydride.

Organosilicon ethers of ricinoleic acid

Russian Chemical Bulletin, 2020
Interaction of vinyl trichlorosilane with sodium salt of ricinoleic acid is investigated. It is established that the composition and structure of silicon-containing ethers depends on the content of crystallization water in sodium ricinoleate, and the concentration and nature of solvent.

Macrolactones and Polyesters from Ricinoleic Acid

Biomacromolecules, 2005
A systematic study on the synthesis, characterization, and polymerization of ricinoleic acid (RA) lactone is reported. Ricinoleic acid lactones were synthesized by refluxing pure ricinoleic acid in chloroform (10 mg/mL) with dicyclohexylcarbodimide and (dimethylamino)pyridine as catalyst.

Phosphorus-containing esters of ricinoleic acid

AIP Conference Proceedings, 2021
The interaction of thiotrichlorophosphate with the sodium salt of ricinoleic acid in alcohol-benzene mixtures has been studied. Tris(ricinoleate) thiophosphate has been isolated with high yield (80%). Its composition has been determined. The structure of the product was characterized by the following methods: 1H, 13C, 31P NMR, IR spectroscopy, gel ...

Ricinoleic Acid Catabolism in Peroxisomes

Botanica Acta, 1991
AbstractPeroxisomes from castor bean endosperm and mung bean hypocotyl completely degrade ricinoleic acid (12‐D‐hydroxy‐9‐cis‐octadecenoic acid) to acetyl‐CoA. Concomitant NADH formation occurred with a stoichiometry of 9 nmol NADH formed per 1 nmol ricinoleate degraded.

Lactic Acid and Ricinoleic Acid Based Copolyesters

Macromolecules, 2005
Copolyesters based on purified ricinoleic (RA) and lactic (LA) acids with different RA:LA ratios were synthesized by thermal polycondensation and by transesterification of high molecular weight poly(lactic acid) (PLA) with ricinoleic acid and repolyesterification.

Stable polyanhydride synthesized from sebacic acid and ricinoleic acid

Journal of Controlled Release, 2017
Poly(anhydride) are unstable and prone to hydrolytic degradation and depolymerisation via anhydride interchange. They are stored at -20°C, packed under inert atmosphere until use. We synthesized a new poly(anhydride) from ricinoleic (RA) and sebacic (SA) acid with alternating ester-anhydride structure that is stable at 25°C for over 18months.

Final Report on the Safety Assessment of Ricinus Communis (Castor) Seed Oil, Hydrogenated Castor Oil, Glyceryl Ricinoleate, Glyceryl Ricinoleate SE, Ricinoleic Acid, Potassium Ricinoleate, Sodium Ricinoleate, Zinc Ricinoleate, Cetyl Ricinoleate, Ethyl Ricinoleate, Glycol Ricinoleate, Isopropyl Ricinoleate, Methyl Ricinoleate, and Octyldodecyl Ricinoleate1

International Journal of Toxicology, 2007
The oil derived from the seed of the Ricinus communis plant and its primary constituent, Ricinoleic Acid, along with certain of its salts and esters function primarily as skin-conditioning agents, emulsion stabilizers, and surfactants in cosmetics, although other functions are described.

Synthesis of phosphatidylcholines containing ricinoleic acid

Tetrahedron, 2001
Abstract 1,2-Diricinoleoyl- and 1-ricinoleoyl-2-oleoyl-sn-glycero-3-phosphocholine were synthesised with good yields. The synthesis started with the preparation of ricinoleic acid from castor oil. The choice of a suitable agent to protect the –OH group of ricinoleic acid was a key factor to afford the final products.
