Title:
METHOD FOR PRODUCING TRANS, TRANS-4,4'-BICYCLOHEXYLDICARBOXYLIC ACID
Document Type and Number:
Japanese Patent JP2008231075
Kind Code:
A
Abstract:

To provide a method for efficiently producing trans, trans-4,4'-bicyclohexyldicarboxylic acid useful as a raw material for medicines, agrochemicals, liquid crystal materials, etc.

The method for producing trans, trans-4,4'-bicyclohexyldicarboxylic acid of trans, trans-isomer comprises isomerizing a mixture of the cis-isomer and the trans-isomer of trans, trans-4,4'-bicyclohexyldicarboxylic acid in a protonic solvent having a boiling point of 130C in the presence of an alkali metal salt under heating. The high-purity trans, trans-4,4'-bicyclohexyldicarboxylic acid is produced without requiring a high temperature in the reaction.
