    Abstract: A method of transalkoxylation of nucleophilic compounds in which an alkoxylated and a nucleophilic compound are combined in a suitable vessel and reacted in the presence of a heterogeneous catalyst under conditions capable of transferring at least one hydroxyalkyl group from the alkoxylated compound to the nucleophilic compound. The method is especially useful in the transalkoxylation of alkanolamines to transfer a hydroxyalkyl group from an alkanolamine having a greater number of hydroxyalkyl groups to an alkanolamine having a lesser number of hydroxyalkyl groups.

    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. The present invention also relates to a colourless TEA having a high purity, that can be obtained by the process according to the invention and especially has a high resistance to coloration.
