What is Ricinoleic Acid?

Ricinoleic acid, formally called 12-hydroxy-9-cis-octadecenoic acid, is a fat. It is an unsaturated omega-9 fat as well as a hydroxy acid that is the main element of seed oil gotten from the seeds of the mature castor plant (Ricinus communis, Euphorbiaceae) or the sclerotia of ergot. About 90% of the fats contained in castor oil are triglycerides developed from ricinoleic acid.

Ricinoleic Acid Uses

Ricinoleic acid particles include hydroxyl, double bonds as well as carboxyl practical teams, which can go through a variety of responses to obtain a selection of high value-added chemicals. Among them, the hydroxyl team can go through esterification, halogenation, polyurethane reaction, alkoxylation, sulfation response, etc; the double bond can go through addition, polymerization, hydrogenation, epoxidation and various other reactions; the carboxyl team can undergo esterification, amidation, saponification Wait on response. Ricinoleic acid and its by-products play a crucial function in the chemical market and are commonly utilized. They have an irreplaceable setting in the oleochemical sector. Ricinoleic acid can be straight utilized as a basic material for materials, a dispersant for pigments and also dyes in printing inks, and also a leather softener; it can be utilized to prepare important chemical intermediates such as sebacic acid, heptanoic acid, and undecenoic acid; as well as it can be made use of to prepare surface-active agents, plasticizers, lubricating substances, and so on; ricinoleic acid downstream items ricinol, suberic acid, methyl ricinoleate and azelaic acid can be made use of in plasticizers, emulsifiers and also soap solutions; sebacic acid can be prepared Nylon collection products, plasticizers, rubber, etc; some ricinoleic acid by-products can additionally be made use of as antistatic agents and softeners for hair. There are lots of sorts of ricinoleic acid series surfactants, among which sulfonated castor oil and also fat soaps acquired by hydrolysis of castor oil are the two most typical types. Utilizing concentrated sulfuric acid as the sulfonating reagent, sulfonated ricinoleic acid is acquired, which has excellent emulsifying power and detergency buildings and can be utilized as a detergent component. Esterify RA to obtain methyl ricinoleate, and afterwards go through amidation and quaternization to acquire a new castor oil-based quaternary ammonium salt cationic surfactant.

Furthermore, some studies have synthesized a brand-new kind of ricinoleic acid-based mercaptotriol (STRA) and used it as a plasticizer for ethyl cellulose (EC) membranes. After incorporating with STRA, the EC membrane has both ductility and also hydrophilic residential properties. has actually been improved, so this new STRA can be used as a basic material for hydrophobic EC membrane layers. There are also research studies on the synthesis of epoxidized castor oil (ECO) as well as castor oil phosphate ester (COPE). Polyvinyl chloride (PVC) mixing systems were prepared utilizing ECO as well as deal as complementary plasticizers specifically, which boosted the efficiency of PVC blends. thermal stability. Furthermore, research studies have manufactured a new polyanhydride RA-SA based upon RA as well as sebacic acid (SA), which can be used as an injectable car. Octyl 10,12-dihydroxy-9-octyloxystearate, as a diester biolubricant stemmed from ricinoleic acid, has a reduced pour point and also unpredictable loss, suggesting that it is a prospective eco-friendly biolubricant. Lubricating substance base oil. Ricinoleic acid-based biopolyester is made use of as a surface modifier for magnetic Fe3O4. Biocatalytic production of undec-9-enoic acid and also undec-9-enoic acid heptyl ester making use of recombinant Corynebacterium glutamicum biocatalytic RA.


Determination of Ricinoleic Acid Content

The function of the creation CN102830190A is to make use of a technique for measuring the outright material of ricinoleic acid in castor seeds, aiming to fix the issue that existing measurement techniques can not accurately determine the absolute content of oleic acid in castor beans.

The object of today invention is to offer an approach for determining the outright material of ricinoleic acid in castor seeds. The technique consists of:

Arbitrarily select 100 castor seeds as well as determine the 100-seed weight as well as bit rate;
Extract crude fat from 100 castor seeds utilizing Soxhlet extraction approach, as well as determine the unrefined fat web content of castor seeds;
Fat methyl esters prepared from castor seeds were utilized for chromatographic evaluation, and also through search and also computation, the loved one material of each fat was obtained.

Further, the decision method makes use of chromatographic analysis of fat methyl esters of castor seeds.

In the approach for determining the absolute content of ricinoleic acid in castor seeds of the here and now development, the fatty acid methyl ester prepared from castor seeds is subjected to chromatographic evaluation to acquire its total ion current; via access as well as calculation, the crude fat in castor seeds is acquired. The proportion of 8 fat components; the absolute web content of each fat in castor seeds is transformed, consisting of the outright material of ricinoleic acid; the outright content of ricinoleic acid in castor seeds is identified just, promptly and also accurately.

Preparation of Ricinoleic Acid

Prep work of ricinoleic acid by typical stress hydrolysis. Oil and water are immiscible and difficult to hydrolyze. After including an acidic emulsifier with high catalytic performance, it can release H+ ions, turn on the activity of oil and water molecules, enhance the possibility of molecular accident, and also boost the solubility as well as ionization level of water in castor oil, emulsifying the oil-water two-phase liquid. The emulsifier right here is naphthalene sulfonate decyl fat, dodecyl benzoic acid or their sodium salts. Mix the 3 ingredients, warm to 50 ° C, and perform a sulfonation reaction for 3 hrs to get the emulsifier “naphthalene sulfonate decyl fat”:

The above heavy steam is directly warmed, as well as the hydrolysis can be finished by reacting under boiling conditions for 8 to 10 hours, and ricinoleic acid is created.
