반응 단계
To a solution of ethylene glycol (248 g, 4 moles) and boron trifluoride etherate catalyst (1 ml) in dichloromethane (20 ml) preheated to 45° C. was added t-BGE (130 g, 1 mole) dropwise at such a rate so as to maintain a gentle reflux. After completion of addition, stirring was continued for about 15 hours. The solution was then adjusted to pH 7.5 by addition of sodium hydroxide and the product removed by distillation. Tertiary butoxymethyl diethylene glycol was obtained in 71 percent yield having a boiling point of 105° C.-115° C./1 mm.
