Title
(DE) VERFAHREN ZUR HERSTELLUNG VON 1-METHYL-1-ALKOXYCYCLOPENTANEN
(EN) METHOD FOR THE PRODUCTION OF 1-METHYL-1-ALKOXYCYCLOPENTANES
(FR) PROCÉDÉ DE PRÉPARATION DE 1-MÉTHYL-1-ALKOXYCYCLOPENTANES
Abstract
(DE)
Verfahren zur Herstellung von Cyclopentanderivaten der Formel (I), in der R für eine C1– bis C10-Alkylgruppe steht, dadurch gekennzeichnet, dass Cyclohexanol oder Cyclohexen oder Gemische beider Verbindungen zu 1-Methyl-1-cyclopenten umgesetzt wird (1.Stufe) und anschließend ein C1 bis C10 Alkanol an die Doppelbindung des 1-Methyl-1-cyclopentens addiert wird (2.Stufe).
(EN)
The invention relates to a method for the production of cyclopentane derivatives of formula (I), in which R represents a C1-C10 alkyl group, characterized in that cyclohexanol or cyclohexene or mixtures of both compounds are reacted to 1-methyl-1-cyclopentene (first stage), a C1-C10 alkanol being added subsequently to the double bond of the 1-methyl-1-cyclopentene (second stage).
(FR)
L'invention concerne un procédé de préparation de dérivés de cyclopentane représentés par la formule (I) dans laquelle R est un groupe C1- à C10-alkyle, caractérisé en ce que du cyclohexanol et du cyclohexène ou des mélanges de ces deux composés sont transformés en 1-méthyl-1-cyclopentène (1ère étape), puis un C1- à C10-alcanol est additionné à la double liaison du 1-méthyl-1-cyclopentène (2ème étape).
