mono-methyl polyethylene glycol 5,000 glycidyl ether

反応条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To ethylene glycol monomethyl ether (86.4 g, 2.27 moles), ground caustic soda (16.7 g, 0.83 moles) was added by several portions and caustic soda was dissolved by heating to 80° C. Ethylene glycol glycidyl methyl ether (50 g, 0.76 moles) was then added dropwise. After the completion of the dropwise addition, the solution was stirred for 2 hours and then air-cooled at room temperature. The solution was neutralized with hydrochloric acid and a salt was deposited by adding acetone, followed by filtration. Low-boiling materials were removed under reduced pressure to obtain 67 g (yield 85%) of 1,3-bis(2-methoxyethoxy)-2-propanol. was dissolved After the completion of the dropwise addition air-cooled at room temperature followed by filtration were removed under reduced pressure
