Description:

Add 120# gasoline to the reactor, Under stirring, aluminum isopropoxide is added as catalyst (the amount of catalyst is 1.01% ~ 1.03% of the total amount of monomer). After replacing the air in the meeting with nitrogen, monomer ethylene oxide is added (solvent: ethylene oxide = 2:1, mass ratio). React at 10 ~ 20 ℃ for 4H. Then gradually raise the temperature to 35 ~ 40 ℃, and then react for 3h. After the polymerization reaction, transfer the material to the distillation kettle, evaporate the solvent, cool and crystallize, filter to obtain the crude product. Vacuum dry to obtain the finished product.

Application:

Colorless viscous liquid or white solid. Low toxicity! Soluble in water and many organic solvents, easily soluble in aromatic hydrocarbons, slightly soluble in aliphatic hydrocarbons. It does not hydrolyze for a long time, is stable to heat, and does not react with many chemical reagents. Some metal salts can dissolve in polyethylene glycol at about 100 ℃ and remain stable at room temperature. These metal salts include chlorides of calcium, cobalt, copper, iron, magnesium, manganese, tin and zinc, potassium iodide and ethyl mercury. It can be used as plasticizer, softener, wetting agent, lubricant, solvent and adhesive. It can also be used as perfume and pharmaceutical preparation.
