| Introduction | ethylene glycol ether is a kind of ethylene glycol monoether compounds. The structure of ethylene glycol monoethers contains ether bonds, hydroxyl groups and different alkyl groups, which not only have water solubility, but also can dissolve organic molecules, synthetic polymers and natural polymers, widely used as industrial solvents, but also can be used as antifreeze, surfactants, printed circuit board adhesives, skin care additives have broad application prospects in industry. |
| preparation | 46.0gMg(NO3)2 · 6H2O,13.1gCo(NO3)2 · 6H2O was dissolved in 1.4 ml of distilled water, and then 25% gLa(NO3)3 · 6H2O was added to obtain a salt solution. The resulting solution was mixed with by weight of concentrated ammonia water by concurrent dropwise addition, adjust the pH of the mixed solution to 9, react at atmospheric pressure and 40 ℃ for 1H, then cool to room temperature, then aging for 20H, after Conventional Suction filtration, washing, drying, roasting at 500 ℃ for 4H, the monolithic catalyst was obtained and pulverized to 40-60 mesh to obtain the desired catalyst, labeled as GM1. The prepared catalyst GM1 was placed in a tubular membrane in a continuous membrane reactor, and nitrogen was purged outside the membrane, the gas phase ethoxylation of ethylene oxide with ethanol in a molar ratio of 3: 1 was carried out. The ethanol was gasified in a pre-heater at 90 °c, and the temperature of the membrane reactor was maintained at 100 °c, the gas space velocity was 1.5 × 103ml · g-1 · h-1 to obtain ethylene glycol ethyl ether. |
| Use | used as solvent, extraction agent, water repellent and organic intermediate used as nitrocelluloid, pseudo paint and other solvents, leather colorants and emulsion stabilizers The product is a low volatile solvent. It is used as a solvent for nitrocelluloid, lacquer, natural and synthetic resins, etc., and can also be used for leather colorants, emulsion stabilizers, paint diluents, paint strippers, textile fiber colorants, etc. In addition, it is also an intermediate for the production of acetate. used as solvents, as well as leather colorants, emulsifiers, stabilizers, coating diluents, paint strippers, organic intermediates, etc. solvents for nitrocellulose, resin, paint, etc. Leather colorant. Emulsion stabilizer. ethylene glycol ethyl ether is a low volatility solvent. This product is mainly used for the solvent of nitrocellulose paint and flying wing paint, can also be used as varnish coating agent, purification liquid, dye bath, water-soluble pigment and dye solution, refined leather solvent, and can increase the stability of latex.

| production method | results from the reaction of ethylene oxide with ethanol. Ethylene oxide was slowly added to anhydrous ethanol at 25-30 °c until the temperature rose to 70 °c and allowed to stand overnight after completion of the reaction. Ethanol was recovered, neutralized with 10% sodium hydroxide solution to pH = 8, and fractionated to obtain a crude product. By distillation, the 133.5-135.5 °c fraction was collected to obtain the finished product. Consumption of ethylene oxide 863kg per ton of product, anhydrous ethanol 1020kg. |
