  • Patent number: 8558029
    Abstract: 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.
