Title:
METHOD FOR THE PRODUCTION OF 1-METHYLCYCLOPENTANE DERIVATIVES
Document Type and Number:
WIPO Patent Application WO/2012/055754
Kind Code:
A3
Abstract:
The invention relates to a method for the production of 1-methylcyclopentene by the thermal reaction of cyclohexanol or cyclohexene or mixtures of both compounds to 1-methylcyclopentene, characterized in that the obtained byproducts 3-methylcyclopentene and 4-methylcyclopentene (double bond isomers of 1-methylcyclopentene) are fed back to the reaction.
