Description

Verfahren zur Herstellung höherer aliphatischer Alkohole Es ist bereits vorgeschlagen worden, Fettsäuren zu den entsprechenden Uochmolekularen aliphatischen Alkoholen zu reduzieren, indem man auf die Fettsäuren. bei erhöhter Temperatur Wasserstoff in Gegenwart von Hydrierungskatalysatoren zur Einwirkung bringt.Process for making higher aliphatic alcohols It already is It has been proposed to convert fatty acids to the corresponding high molecular weight aliphatic Reduce alcohols by looking at the fatty acids. hydrogen at elevated temperature brings into action in the presence of hydrogenation catalysts.

Es wurde nun -gefunden, daß es für die Reduktion der Fettsäuren nicht nötig ist, einen nach den üblichen umständlichen Methoden hergestellten Metallkatalysator zu benutzen, sondern. daß man technisches Kupfercarbonat, wie es im Handel erhältlich ist, als solches der zu reduzierenden Säure beimischen kann und eine glatte Reduktion zu dem entsprechenden hochmolekularen Alkohol erhält.It has now been found that it is not necessary for the reduction of fatty acids is necessary, a metal catalyst prepared by the usual cumbersome methods to use but. that one technical copper carbonate, as it is commercially available is, as such, can be admixed with the acid to be reduced and a smooth reduction to the corresponding high molecular weight alcohol.

Die Druck- und Temperaturbedingungen der Reduktion entsprechen den üblichen Bedingungen bei der katalytischen Reduktion von Fettsäuren und Fettsäureesbern zu Alkoholen bei Gegenwart von Metallkatalysatoren.The pressure and temperature conditions of the reduction correspond to usual conditions in the catalytic reduction of fatty acids and fatty acid sucers to alcohols in the presence of metal catalysts.

Diese Wirkung des technischen Kupferca.rbonates ist um so überraschender, da chemisch reines Kupfercarbonat, in derselben Menge und unter sonst gleichen Bedingungen angewendet, sehr viel schlechtere Resultate ergibt.This effect of the technical copper carbonate is all the more surprising, as chemically pure copper carbonate, in the same amount and under otherwise identical conditions applied, gives much worse results.

Die Verwendung von technischem Kupfercarbönat an Stelle der bisher angewendeten, durch eine komplizierte Vorbehandlung erhaltenen Katalysatoren bedeutet eine wesentliche. Vereinfachung und Verbilligung des katalytischen Reduktionsverfahrens.The use of technical copper carbonate instead of the previous one used means catalysts obtained by a complicated pretreatment an essential. Simplification and cheaper of the catalytic reduction process.
