    • Phenolic glycol ethers, e.g., ethylene glycol phenyl ether, are prepared by a continuous, nonaqueous process comprising the steps of (A) contacting under isothermal reactive conditions in a first reactor or reaction zone an alkylene oxide, e.g., ethylene oxide, with (i) a stoichiometric molar excess of a phenolic compound, e.g., phenol, and (ii) a catalytic amount of a base, e.g., sodium hydroxide, homogeneously dispersed throughout the phenolic compound, to form a first intermediate phenolic glycol ether product, (Bj transferring the first intermediate phenolic glycol ether product to a second reactor or reaction zone, and (C) subjecting the first intermediate phenolic glycol ether product to adiabatic reactive conditions in the second reactor or reaction zone to form a second intermediate phenolic glycol ether product comprising phenolic glycol ether, unreacted phenolic compound, catalyst, water and byproduct glycols. In addition, the mono-/di-product weight ratio can be adjusted by increasing or decreasing the amount of base catalyst employed.
    • 酚醛二醇醚,例如乙二醇苯基醚,通过连续的非水性方法制备,包括以下步骤:(A)在等温反应条件下在第一反应器或反应区中接触环氧烷,例如环氧乙烷与(i )化学计量摩尔过量的酚类化合物,例如苯酚,和(ii)催化量的碱,例如均匀分散在整个酚类化合物中的氢氧化钠,形成第一中间体酚二醇醚产物(Bj转移 将第一中间体酚二醇醚产物加入到第二反应器或反应区中,和(C)使第一中间体酚二醇醚产物在第二反应器或反应区中进行绝热反应条件以形成包含酚二醇的第二中间体酚二醇醚产物 醚,未反应的酚类化合物,催化剂,水和副产物二醇,另外,单/二产物重量比可以通过 增加或减少所用的碱催化剂的量。
