Fatty alcohol polyoxyethylene ether - Reference Information
| properties | the number of ethoxy groups in fatty alcohol polyoxyethylene ether molecules can be adjusted in the synthesis process, so a series of non-ionic surfactants with different properties and uses can be prepared. Fatty alcohol polyoxyethylene ether is the most important class of nonionic surfactants. The ether bond in the molecule is not easy to be destroyed by acid and alkali, so it has high stability, good water solubility, electrolyte resistance, easy biodegradation, and small foam. Fatty alcohol polyoxyethylene ether is a colorless liquid or wax. Its carbon chain length, ethylene oxide addition number and distribution have a great influence on the physical and chemical properties and application performance of the product. The cloud point, relative density, viscosity, etc. of fatty alcohol polyoxyethylene ether increase with the increase of the addition number of ethylene oxide, but its surface activity such as decontamination ability, foaming, wetting and dispersing power It starts to increase with the increase of the addition number of ethylene oxide. After reaching the maximum, the addition number of ethylene oxide continues to increase, and its surface activity begins to decrease again. Fatty alcohol polyoxyethylene ether has good compatibility with other surfactants, is not sensitive to hard water, and has good low-temperature washing performance, but with the increase of water temperature, its solubility will gradually decrease. In the pH range of 3~11, fatty alcohol polyoxyethylene ether hydrolysis is stable. However, they also oxidize slowly in the air, producing some oxidation products, such as acetaldehyde and hydroperoxides, which are more toxic to the skin than surfactants that have not yet occurred. |
| use | fatty alcohol polyoxyethylene ether is widely used to produce fatty alcohol polyoxyethylene ether sodium sulfate (AES). The physical properties of fatty alcohol polyoxyethylene ether make it unfavorable to prepare washing powder, but it is an ideal raw material for liquid detergent. It has better descaling ability than sodium alkylbenzene sulfonate for various fibers, and is especially suitable for washing off grease and dirt excreted by human body from synthetic fiber fabrics. Abroad. The main use of fatty alcohol polyoxyethylene ether is as a synthetic detergent. The domestic commodity brand is Pingjia series products. Except for some of them used for compound liquid detergent, they are mainly used as leveling agent and stripping agent in printing and dyeing industry, raw wool detergent in wool spinning industry, and spinning oil agent in chemical fiber industry. It is widely used as a leveling agent for various dyes and a stripping agent for vat dyes in the textile industry. The general dosage of wool retarding agent is 0.2~1/L. It can be used as a component of spinning finishes for synthetic fibers such as polyester. Used as emulsifier in latex industry and petroleum drilling fluid. This product has unique emulsifying properties for stearic acid, paraffin, mineral oil, etc., and is a component of emulsifier during polymer emulsion polymerization. It can also be used as an emulsifier for glass fiber lubricating oil. This product can remove the dye dispersed on the fabric of the dirt, improve sodium alkylbenzene sulfonate synthetic detergent decontamination ability, reduce the antistatic effect of the fabric. |
| Synthesis | Fatty alcohol polyoxyethylene ether is composed of fatty alcohol (C10 ~ C18 primary alcohol or secondary alcohol) in alkali catalyst (caustic alkali or sodium methoxide) Addition reaction with ethylene oxide occurs in the presence. The reaction rate of primary alcohol is greater than that of secondary alcohol, and the reaction rate of primary alcohol and ethylene oxide to form an adduct is close to the rate of polyoxyethylene ether chain growth. As a result, the final product is actually a mixture of polyoxyethylene ethers with different degrees of polymerization, including the raw alcohol that is not oxygenated. Since the application performance of fatty alcohol polyoxyethylene ether depends to a large extent on the polymerization degree m of polyoxyethylene ether, how to make the distribution curve of n in the obtained product narrowest is the key to improve product quality in the production of fatty alcohol polyoxyethylene ether. It has been found that the catalyst has a great influence on the distribution curve: basic catalysts, such as sodium methoxide, get a wide distribution curve; use acidic catalysts, such as boron trifluoride, tin tetrachloride, antimony pentachloride and trifluoride Ether complexes, etc., get a narrow distribution curve. Although acid catalysis can reach a narrow distribution, it has not been used in production so far because it will increase by-products (such as polyethylene glycol, dioxane, etc.) and equipment corrosion problems. At present, the improvement of catalysts is still an important research topic. |
| application | 1. washing industry: as a non-ionic surfactant, it plays the role of emulsification, foaming and decontamination, and is the main active ingredient of hand sanitizer, laundry detergent, shower gel, washing powder, detergent and metal cleaning agent. 2. Textile printing and dyeing industry: can be used as textile printing and dyeing auxiliaries; It plays an emulsifying role and is often used as emulsified silicone oil, penetrant, leveling agent and polypropylene oil agent. 3. Paper industry: can be used as deinking agent, blanket detergent, deresin agent. 4. In other cases, it can also be used as pesticide emulsifier, crude oil demulsifier, lubricating oil emulsifier, etc. |
