Description
Aufgabe der Erfindung war es daher, ein neues Verfahren zur Herstellung eines Produkts, das relativ viel m-Iso-camphylphenol enthält, zur Verfügung zu stellen. The object of the invention was therefore to provide a new process for the production of a product which contains a relatively large amount of m-iso-camphylphenol.
Die Erfindung betrifft somit ein Verfahren zur Herstellung eines m-Isocamphylphenol enthaltenden Isomerengemischs, das dadurch gekennzeichnet ist, dass man p-Isocamphylphenol oder ein p-Isocamphylphenol enthaltendes Isomerengemisch mit wasserfreiem Fluorwasserstoff umsetzt. The invention thus relates to a process for the preparation of an isomer mixture containing m-isocamphylphenol, which is characterized in that p-isocamphylphenol or an isomer mixture containing p-isocamphylphenol is reacted with anhydrous hydrogen fluoride.
Als Ausgangsmaterial für das erfindungsgemässe Verfahren kann man p-Isocamphylphenol verwenden, bevorzugt ist jedoch ein Gemisch, das p-Isocamphylphenol enthält und mindestens ein anderes Isocamphylphenol-Isomeres. Derartige Gemische sind leicht erhältlich, ein geeignetes Verfahren für ihre Herstellung ist die Umsetzung von Camphen mit Phenol. P-Isocamphylphenol can be used as the starting material for the process according to the invention, but a mixture which contains p-isocamphylphenol and at least one other isocamphylphenol isomer is preferred. Such mixtures are readily available, a suitable method for their preparation is the reaction of camphene with phenol.
Im erfindungsgemässen Verfahren wird vorzugsweise ein p-Isocamphylphenol enthaltendes Gemisch verwendet, A mixture containing p-isocamphylphenol is preferably used in the process according to the invention,
das durch Umsetzen von Camphen mit Phenol in Gegenwart von wasserfreiem Fluorwasserstoff erhalten worden ist. which has been obtained by reacting camphene with phenol in the presence of anhydrous hydrogen fluoride.
Somit bietet das erfindungsgemässe Verfahren die Möglichkeit, das gewünschte m-Isocamphylphenol enthaltende Produkt in einer einzigen Stufe aus Camphen und Phenol herzustellen. The process according to the invention thus offers the possibility of producing the desired product containing m-isocamphylphenol in a single step from camphene and phenol.
Die erfindungsgemässe Isomerisierung des p-Isocamphyl-phenols oder des p-Isocamphylphenol enthaltenden Gemisches mit wasserfreiem Fluorwasserstoff erfolgt bei einer Temperatur von 0 bis 120°C, vorzugsweise 60 bis 80°C. Der Fluorwasserstoff wird dabei zweckmässigerweise in einem 10- bis 60fachem molaren Überschuss, bezogen auf p-Isocamphylphenol, verwendet. The isomerization according to the invention of the p-isocamphylphenol or of the mixture containing p-isocamphylphenol with anhydrous hydrogen fluoride takes place at a temperature of 0 to 120 ° C., preferably 60 to 80 ° C. The hydrogen fluoride is expediently used in a 10- to 60-fold molar excess, based on p-isocamphylphenol.
Auch bei der Herstellung des p-Isocamphylphenol enthaltenden Gemisches durch Umsetzen von Camphen und Phenol in Gegenwart von wasserfreiem Fluorwasserstoff werden die gleichen Reaktionsbedingungen angewendet, d.h. Temperaturen von 0 bis 120°C, vorzugsweise 60 bis 80°C. Der Fluorwasserstoff wird dabei in einem 10- bis 40fachen Überschuss, bezogen auf das Phenol, verwendet. Auch das Phenol wird vorzugsweise im Überschuss verwendet, z.B. in einem molaren Verhältnis von Phenol zu Camphen von 2:1 bis 4:1. Gegebenenfalls kann man bei der Umsetzung zusätzlich noch andere Fluoride verwenden, z.B. Bortrifluorid, Antimonpentafluorid, Phosphorpentafluorid und Titantetrafluorid. In diesem Fall werden niedrigere Temperaturen bevorzugt, z.B. 20 bis 30°C. The same reaction conditions are also used in the preparation of the mixture containing p-isocamphylphenol by reacting camphen and phenol in the presence of anhydrous hydrogen fluoride, i.e. Temperatures from 0 to 120 ° C, preferably 60 to 80 ° C. The hydrogen fluoride is used in a 10- to 40-fold excess, based on the phenol. The phenol is also preferably used in excess, e.g. in a molar ratio of phenol to camphene from 2: 1 to 4: 1. If necessary, other fluorides can also be used in the reaction, e.g. Boron trifluoride, antimony pentafluoride, phosphorus pentafluoride and titanium tetrafluoride. In this case lower temperatures are preferred, e.g. 20 to 30 ° C.
Das im erfindungsgemässen Verfahren hergestellte Produkt wird zur Herstellung eines Produkts, das 3-Isocamphyl-cyclohexanol enthält, verwendet. Diese Herstellung erfolgt in herkömmlicher Weise durch Hydrierung, insbesondere durch katalytische Hydrierung, wie mit einem Edelmetall, z.B. Rhodium, als Katalysator. The product produced in the process according to the invention is used to produce a product which contains 3-isocamphyl-cyclohexanol. This preparation is carried out in a conventional manner by hydrogenation, in particular by catalytic hydrogenation, such as with a noble metal, e.g. Rhodium, as a catalyst.
