Description
Verfahren zur Darstellung alkylierter Cyclohexanole In dem Patent 478 273 ist ein Verfahren zur Darstellung alkylierter Cy#lohexanole geschützt, wonach man Kondensationsprodukte aus Ketonen und Phenolen der Einwirkung von Wasserstoff bis zur Aufnahme von 14 Atomen Wasserstoff unterwirft. Es wurde gefunden, daß sich das Verfahren auch auf andere Dioxydiphenylmethanderivate anwenden läßt, z. B. auf die Kondensationsprodukte aus Aldehyden und Phenolen der Formel- worin R Wasserstoff, Alkyl oder Aryl be- deutet.Process for the preparation of alkylated cyclohexanols In the patent 478 273 a process for the preparation of alkylated cyclohexanols is protected, according to which condensation products of ketones and phenols are subjected to the action of hydrogen up to the absorption of 14 atoms of hydrogen. It has been found that the process can also be applied to other dioxydiphenylmethane derivatives, e.g. B. on the condensation products of aldehydes and phenols of the formula wherein R is hydrogen, alkyl or aryl indicated loading.
Beispiel i p-Dio-xydiphenylmethylmethan wird mit etwa l"/, eines manganhaltigen -Nickelkatalysators, bestehend aus 58,o'/" Nickel, 36,7'/" Kupfer, 4,45'/" Kobalt und o,85"/" Mangan, mit Wasserstoff unter Druck bei etwa 170' behandelt, bis i4Atome Wasserstoff aufgenommen sind. Man erhält 4-Äthylc#vcloh,exanol neben Cyclohexanol.Example i p-Dio-xydiphenylmethylmethane is used with about 1 "/, of a manganese-containing nickel catalyst, consisting of 58.0 '/" nickel, 36.7' / "copper, 4.45 '/" cobalt and 0.85 "/ "Manganese treated with hydrogen under pressure at about 170 ' until 14 atoms of hydrogen are absorbed. 4-Ethylcloh, exanol is obtained in addition to cyclohexanol.
Beispiel :2 p-Dioxydiphenylmethan wird, wie in Beispiel i des Hauptpatents, bis zur Aufnahme von 14.,'£tomen Wasserstoff behandelt. Man erhält 4-Methylcyclohexanol neben Cyclohexanol.Example: 2 p-Dioxydiphenylmethane is, as in example i of the main patent, Treated until 14 atoms of hydrogen were absorbed. 4-methylcyclohexanol is obtained next to cyclohexanol.
Beispiel 3 p-Dioxydiphenylmethylmethan wird in Ge- genwart eines aus den Nitraten des Nickels, Kupfers und Kobalts als Carbonate gefällten Katalysators, der 58,60/" Nickel, 35,71, Kupfer und 4,7"/" Kobalt enthält, unter Druck mit Wasserstoff behandelt, bis i4.,#£tome aufgenommen sind. Man erhält die Reaktionsprodukte nach Beispiel i.Example 3 p-Dioxydiphenylmethylmethan is in overall genwart one of the nitrates of nickel, copper and cobalt precipitated as carbonates catalyst 58,60 / "nickel, 35,71, copper and 4.7" / "contains cobalt, under pressure Treated with hydrogen until 14 atoms have been taken in. The reaction products according to Example 1 are obtained.
