A method for producing glycols

摘要: This invention relates to a method for producing glycols. Such is particularly useful preparing ethylene glycol from oxide and water. The of this synergistic combination the process evaporation, absorption, reaction, combined enhance reactions yields epoxides with compounds containing hydroxy functional groups. comprises making in an evaporation column reactor as follows: (a) feeding compound into reactor; (b) epoxide such that contacted hydroxyl reaction zone under conditions substantially all reacts form product comprising which dissolved liquid compound; (c) removing mixture away zone; (d) heating at least some evaporated glycol; (e) condensing refluxing combining it Step (a). In one aspect invention, feed described enter through two distinct ports within reactor. another synergistically conducted sequential columns together multiple effect
