Properties, Uses and Production Process of Fatty Alcohol Polyoxyethylene Ethers
[Summary Description] Fatty alcohol polyoxyethylene ether series products at room temperature for colorless transparent liquid or white wax-like body, non-toxic, non-irritating, is a nervous nonionic surfactant, its function with fatty alcohol and ethylene oxide addition number difference and difference.
Fatty alcohol polyoxyethylene ether series products at room temperature for colorless transparent liquid or white wax-like body, non-toxic, non-irritating, is a nervous nonionic surfactant, its function with fatty alcohol and ethylene oxide addition number difference and difference. This product is oil-soluble emulsifier, can enhance the solubility of materials in organic solvents. It is an excellent emulsifier for preparing W/O emulsion, and it is also an important component of synthetic fiber oil. It is used as a solubilizer and defoamer in other industries. Fatty alcohol polyoxyethylene ether is widely used in the production of fatty alcohol polyoxyethylene ether sodium sulfate. The physical function of fatty alcohol polyoxyethylene ether makes it not conducive to the formulation of washing powder, but it is the aspiring material of liquid detergent. It has better detergency for all kinds of fibers than sodium alkylbenzene sulfonate, and is especially suitable for washing the grease and dirt excreted by the human body on synthetic fiber fabrics. In the international. The important use of fatty alcohol polyoxyethylene ether is as synthetic detergent. The commodity trademark is Pingpingjia series products. In addition to one-sided use for compound liquid detergent, it should be used as leveling agent and stripping agent in printing and dyeing industry, as raw wool cleaning agent in wool textile industry, and as spinning oil in chemical fiber industry. The use of non-ionic surfactants in the textile industry is widely used as a leveling agent for all kinds of dyes, recovery dye stripping agent, wool retarder ordinary dosage of 0.2~1/L. It can be used as a component of spinning finish for synthetic fibers such as polyester. Emulsifier in latex industry and kerosene drilling fluid. This product has a strange emulsifying function to stearic acid, paraffin, mineral oil and so on. It is the component of emulsifier in polymer emulsion polymerization. It can also be used as an emulsifier for glass fiber lubricants. This product can remove the dye evacuation gathered in the fabric of the dirt, the progress of sodium alkyl benzene sulfonate synthetic detergent decontamination talent, weaken the anti static effect of the fabric. Fatty alcohol polyoxyethylene ether by fatty alcohol in the presence of alkali catalyst and ethylene oxide addition reaction. The reaction rate of primary alcohols is greater than that of secondary alcohols and the reaction rate of primary alcohols with ethylene oxide to form 1 adducts is close to the rate of polyoxyethylene ether chain enhancement. As a result, the product is actually a mixture of polyoxyethylene ethers with different degrees of polymerization, including non-oxyethylated material alcohols. Because the use function of fatty alcohol polyoxyethylene ether depends to a great extent on the polymerization degree m of polyoxyethylene ether, how to make the diffusion curve in the obtained product very narrow is the link of improving product quality in the production of fatty alcohol polyoxyethylene ether. It has been found that the catalyst has a great influence on the diffusion curve: basic catalysts, such as sodium methoxide. Obtain wide diffuse curve; accept acid catalyst, such as boron trifluoride, tin tetrachloride, antimony pentachloride and boron trifluoride diethyl ether joint venture, narrow diffuse curve. Although acid catalysis can reach narrow diffusion, it has not been accepted in production so far because it will cause by-product increase and equipment erosion problems. The improvement of current related catalysts is still an intense research topic.
