Of An Epihalohydrin Patents (Class 564/476)
  • Publication number: 20140330042
    Abstract: An improved process for making ethoxylated amine compounds such as ethanolamines. The improvement comprises the addition of an acid to the amine compound prior to the addition of ethylene oxide to a reactor wherein the ethoxylated amine compound is prepared. The improvement reduces the concentration of undesirable glycol ether and/or vinyl ether ethoxylate byproducts which may contribute to undesirable properties, such as color and foaming, of the ethoxylated amine compounds.

  • Publication number: 20030100798
    Abstract: The present invention relates to a continuous process for the manufacture of triethanolamine (TEA) comprising, in succession: (i) a step of synthesizing the TEA by continuously bringing ammonia into contact with ethylene oxide under conditions allowing the formation of a reaction mixture comprising mono-, di- and triethanolamines, (ii) a step of continuously separating the ammonia that has not reacted from the reaction mixture and (iii) a step of continuously separating the TEA from the mixture resulting from step (ii). The process is characterized in that a specific mixture of alkanolamines, comprising TEA and from 0.5 to 50% by weight of at least one secondary dialkanolamine, is prepared or isolated from the mixture resulting from step (ii), and in that the TEA is separated and isolated with a degree of purity equal to or greater than 99.2% by weight, by a continuous distillation of the specific mixture of alkanolamines.
