The unique structure of castor oil offers interesting prop-erties, making it appropriate for various industrial applica-tions.
Castor oil is known to consist of up to 90% ricinoleic, 4% linoleic, 3% oleic, 1% stearic, and less than 1% linolenic fatty acids. Castor oil is not commonly used in alkyd resin formulations and there are few reports on the alcoholysis of castor oil triglycerides.
For the preparation of castor oil-based monomers, castor oil was first alcoholized with glycerol, pentaerythritol, and an aromatic diol; BPA propoxylate and the alcoholysis products were then malinated, as shown in Figure (Can ).

Castor oil is increasingly becoming an important bio-based raw material for industrial applications. Castor Oil to Chlorosulfuric Acid The oil is non-edible and can be extracted from castor seeds from the castor plant belonging to the family Euphorbiaceae. The oil is a mixture of saturated and unsaturated fatty acid esters linked to a glycerol.
The presence of hydroxyl group, a double bond, carboxylic group and a long chain. 4National Research Institute for Chemical Technology (NARICT), Zaria E-mail: [email protected] and Technology, Vol. 4, No 5,– X (P) The presence of a hydroxyl group on C of ricinoleic acid makes castor oil unusually polar, thus promoting hydrogen bonding.
This accounts for the oil’s unique. Castor Oil and its Chemistry CasChem supplies a variety of castor oil grades whose uses are dictated by acid value, moisture level, color and purity. Castor Oil, also known as ricinus oil, is a triglyceride of fatty acids which occurs in the seed of the castor plant, Ricinus communis (India, Brazil).
Castor Oil is unique among all fats and oils. Properties & Chemical Composition of Castor Oil – Chemical, Physical Properties & Specifications of Castor Oil Grades & Derivatives – Cold-pressed castor oil has low acid value, low iodine value and a Specific Gravity @ oC % Volatiles by volume @ 21 oC (70 F) Boiling Point oC ( F) Melting Point.
Castor oil is a vegetable oil pressed from castor beans. Castor oil is a colourless to very pale yellow liquid with a distinct taste and odor. Its boiling point is °C ( °F) and its density is g/cm 3. It is a triglyceride in which approximately 90 percent of fatty acid chains are ricinoleates.
Oleate and linoleates are the other significant components. Col d–pressed castor oil has low acid value, low iodine va lue and a slightly higher saponification value than solvent–extracted oil and it is lighter in colour (Table 1) (Ogunniyi, ).
Nkouetcha et al. () used castor oil as an alternative to mineral oil in power transformers . Amdebrhan et al.
() has shown that castor oil can be used as a biolubricant . Castor oil. Castor oil consists largely of glycerides of ricinoleic acid or hydroxy octadecenoic acid. The chemical reactions of castor oil, undecylenic acid, hydroxylstearic acid, sebacic acid, and ny depict the uniqueness of this agricultural oil.
By dehydration, castor oil is converted to a conjugated acid oil similar to tung or oiticica oil. Chlorosulfuric acid (IUPAC name: sulfurochloridic acid) is the inorganic compound with the formula HSO 3 Cl.
It is also known as chlorosulfonic acid, being the sulfonic acid of is a distillable, colorless liquid which is hygroscopic and a powerful lachrymator.
Salts and esters of chlorosulfuric acid are known as chlorosulfates. Castor oil is a popular natural treatment for various common conditions and often used in natural beauty products.
This article lists 7 benefits and uses of castor oil. Castor oil, nonvolatile fatty oil obtained from the seeds of the castor bean, Ricinus communis, of the spurge family (Euphorbiaceae). It is used in the production of synthetic resins, plastics, fibres, paints, varnishes, and various chemicals including drying oils and plasticizers.
Castor oil is.

Many of the benefits gained by using castor oil are a result of its chemical composition. Castor oil is a particular type of triglyceride fatty acid, with nearly 90 percent of its fatty acid substance is ricinoleic acid, which is an unsaturated omega-9 fatty acid.
The ricinoleic acid in castor oil works as an anti-inflammatory and is an. Sigma-Aldrich offers a number of Castor oil products. View information & documentation regarding Castor oil, including CAS, MSDS & more. CASTOR OIL can develop heat spontaneously in the air.

TCC’s Castor Oil is a vegetable oil obtained from the castor bean (technically the castor seed, as the castor plant, Ricinus Communis, is not a member of the bean family).Castor oil is a colorless to very pale yellow liquid with a mild or no odor and somewhat unpleasant taste.
It is a triglyceride in which approximately 90 percent of fatty acid chains are ricinoleic acid.

The dehydration reaction kinetics of castor oil was investigated with sodium bisulfate-sodium bisulfite mixture (SB-SB) or p-toluenesulfonic acid as catalyst. Reactions were carried out at, and °C, and a kinetic model was determined for each case. The reactions with SB-SB catalyst at and °C and with p-toluenesulfonic acid at °C followed second-order kinetics.
Castor oil and Glyceryl Ricinoleate absorb ultraviolet (UV) light, with a maximum absorbance at nm. Castor oil and Hydrogenated Castor Oil reportedly were used in and cosmetic products, respectively, in ; fewer uses were reported for the other ingredients in this group.
The highest reported use concentration (81%) for castor oil. In castor oil and vernonia oil, however, ricinoleic acid and vernolic acid are the major constituents, respectively. Fatty acid compositions of commonly used vegetable oils are listed in Table 1.
The higher the percentage of unsaturation, the better the VOs will be in preparing environmentally acceptable lubricants (base stock/additives).
