| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| overview | glyceryl trioleate is an ester organic substance, which is used as an emulsifier, emulsion stabilizer and wetting agent in food and cosmetics. in drug production, with the continuous expansion of clavulanic acid production, the demand for glyceryl trioleate will be increasing. glyceryl trioleate has been widely used in industry. as a pharmaceutical raw material, it has high requirements for its quality. |
| Application | Glyceryl trioleate has been widely used in industry. As a medicinal raw material, it is generally used as an emulsifier. It can be used in the textile printing and dyeing industry and the pharmaceutical and food fermentation industry. It can also be used as a lubricant in the textile industry; a smoothing agent for post-metal processing; used as an emulsifier and emulsion stabilizer, and wetting agent in food and cosmetics; in medicine, can produce penicillin inhibitor clavulanic acid. |
| preparation | preparation steps are as follows: 1. take a certain proportion of glycerol and oleic acid, wherein the molar ratio of glycerol to oleic acid is 2.3-3.2:1, and the optimal ratio is 2.6-3:1; 2. take 0.1%-1% of the total amount of catalyst, the optimal dose is 0.3%-0.6%, the catalyst is p-toluenesulfonic acid, solid super strong acid, self-made catalyst, etc., among which the best is self-made catalyst; 3., the above-mentioned glycerol, oleic acid and catalyst are added to the reactor, the reactor is heated, and the reaction temperature is kept at 140-220 ℃, the optimal reaction temperature is 190-220 ℃, and the reaction time is 4-8 hours, and the optimal reaction time is 6-8 hours; 4. after the reaction is over, the reactant is dehydrated by vacuum dehydrator until the acid value reaches the standard. The standard is as follows: the appearance is light yellow clear liquid; Acid value/(mgKOH/g):≤ 2; Hydroxyl value/(mgKOH/g):185-205; Saponification value/(mgKOH/g)≤ 25; Moisture: ≤ 1%. |
| traits | colorless and odorless liquid |
| use | glyceryl trioleate can be used as textile lubricant and cosmetic emulsifier. It can also be used as a matrix for cream, lotion and lipstick. Used as an industrial emulsifier and a lubricant in the textile industry. Lubricants used in the textile industry, smoothing agents for metal post-processing Determination of natural fat components. Emulsifiers, opacifying agents, defoamers, finishing agents, lubricants, and pharmaceutical raw materials. |
| production method | add 1 mol of glycerol to the reaction kettle, preheat to 60 ℃, and add 3 mol of oleic acid, water-carrying agent benzene and catalyst sulfuric acid. Reflux is heated under reduced pressure, dehydrated for 4 h, cooled, neutralized with 5% Na2CO3 aqueous solution, separated from the water layer, and dehydrated under reduced pressure to obtain the product. |
