Patent

CA 2298545

The invention relates to a method for producing metal-free and soap-free Guerbet alcohols, whereby primary and/or secondary alcohols containing 2 to 30 carbon atoms are condensed in the presence of alkaline and/or heavy metal catalysts at a high temperature, while water is removed from the reaction, and whereby the product is then directly separated from the reaction by distillation, with no additional purification process.

L'invention concerne un procédé de fabrication d'alcools de Guerbet exempts de métaux lourds et de savons, caractérisé en ce qu'on condense des alcools primaires et/ou secondaires de 2 à 30 atomes de carbone, en présence de catalyseurs alcalins et/ou de catalyseurs aux métaux lourds, à température élevée et tout en éliminant l'eau de la réaction, et en ce qu'on sépare ensuite directement par distillation le produit de la réaction, sans autres étapes de purification.
