CAS NO.764-48-7
High quality 764-48-7 Best price 2-(Vinyloxy)ethanol free sample
2-vinyloxyethanol is a vinyl ether compound. The double bond of the vinyl ether compound is electron-rich due to the electron donor action of the oxygen atom, and can form a stable carbon cation, thereby facilitating the cationic polymerization reaction. Vinyl ether can achieve the purpose of polymer structure modification, block copolymer synthesis and so on. Its homopolymer and copolymer have good adhesion, miscibility and solubility, lubricants, hair sprays, elastomers, foam materials, pesticides and surface protection materials. In addition, the vinyl ether containing hydroxyl group has good performance advantages in the polycarboxylate water reducing agent industry, and has low sensitivity to sand aggregate containing mud and stone powder, the application effect in commercial concrete is better than that of polycarboxylate superplasticizer prepared by traditional methyl allyl alcohol and 3-methyl-3-buten-1-ol.
28g of potassium hydroxide was dissolved in G of ethylene glycol, added to a 4L reactor, heated and simultaneously replaced with nitrogen, then replace the nitrogen with acetylene, heat up to 180 ℃, pressure 0MPaG, control the flow rate of acetylene 240L/h, react for 6 days, continuously add ethylene glycol during the reaction, ethylene glycol is preheated by the pre-heater and then added to the reactor to keep the liquid level of the reaction solution in the reactor unchanged. On the 2nd day and the 4th day, 651g of the reaction solution is replaced with 13g of potassium hydroxide at the same time, the new reaction liquid is preheated in the preheater, and then added into the reactor. The reaction product is continuously taken out of the reactor by acetylene, and the collected liquid is formed after distillation and condensation, the collecting liquid obtained in the receiver has a mass content of 2-methyl -1, 3-dioxolane of 0.23% and a mass content of 2-vinyloxyethanol of 25.40%, and no ethylene glycol divinyl ether, the mass content of ethylene glycol is 74.03%, and the mass content of other total impurities is 0.34%. After rectification of the collected liquid, the purity of 2-vinyloxyethanol is 99.7%.
