Macromolecular Materials and Engineering, 2015 AbstractNovel bio‐based and biodegradable electrospun membranes, containing bactericidal ricinoleic acid (RA) units either by copolymerization with butylene succinate (BS) units or by blending PRA and PBS homopolymers, are characterized in their chemical, thermal, mechanical and surface properties. In the blends E. coli and S.

Engineering Ashbya Gossypii for the Production of Ricinoleic and Linoleic Acid
Chemical Engineering Transactions, 2016 Ashbya gossypii is a natural overproducer of riboflavin or vitamin B2, and it is used nowadays in industrial scale for its production. This filamentous fungus is suitable for metabolic engineering approaches due to the development of a large number of molecular biology techniques, its fully sequenced genome and its high similarity to the model organism

Sucrose Monoesters of Ricinoleic Acid and 12-Ketooleic Acid
The Journal of the Society of Chemical Industry, Japan, 1959 リシノール酸およびそれを酸化して得られる12-ケトオレイン酸のサッカロースモノエステルを合成して,その界面活性剤としての諸性状を明らかにするとともに,既に報告があるサッカロースモノステアレートおよびオレエートと,同一条件下における比較検討を行って,脂肪酸基の構造の差異によるその界面活性能の相違について研究を行った結果,(1)これら4種のエステルの表面張力,界面張力は各濃度においてほぼ同じであり,大きい差異はない。(2)浸透性は1%以下の濃度にあっては12-ケトオレエートが,1%にあってはリシノレートが大で,脂肪酸部に親水基を持つものが良好であり,ステアレート,オレエートと大きい差異を生じた。(3)起泡性は12-ケトオレエート>リシノレート>オレエート>ステアレートの順となり,特にステアレートは小さく,

Development of ricinoleic acid-derived plasticizers and their utilization in polylactic acid
Polymer BulletinAbstract External plasticization technique is widely used to improve Polylactic Acid (PLA) processability and flexibility. The key to successful plasticization is the miscibility and diffusion of plasticizers to the polymer structure to ensure the long-term stability of the material.

Ricinoleic acid-based functional polymers
, 2020 Ricinoleic acid is a component of various bio-based copolymers. However, synthesis and properties of high-molecular-weight polyricinoleate homopolymers are not widely investigated due to high cost of monomer and catalysts. In the first part of this thesis, low cost approach for the synthesis of high-molecular-weight polyricinoleate is presented by ...

Ricinoleic acid-based biopolymers
Journal of Biomedical Materials Research, 1999Polyanhydrides 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, 2020Interaction 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.
