Title
(DE) VERFAHREN ZUR HERSTELLUNG VON METALLFREIEN GUERBETALKOHOLEN
(EN) METHOD FOR PRODUCING METAL-FREE GUERBET ALCOHOLS
(FR) PROCEDE DE FABRICATION D'ALCOOLS DE GUERBET EXEMPTS DE METAUX
Abstract
(DE) Es wird ein Verfahren zur Herstellung von Guerbetalkoholen ohne Schwermetall- und Seifengehalt bereitgestellt, wonach man primäre und/oder sekundäre Alkohole mit 2 bis 30 Kohlenstoffatomen in Gegenwart von alkalischen Katalysatoren und/oder Schwermetall-Katalysatoren bei erhöhter Temperatur und unter Entfernung des Reaktionswassers kondensiert und das Reaktionsprodukt anschließend ohne weitere Reinigungsschritte unmittelbar durch Destillation abtrennt.
(EN) 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.
(FR) 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.
