METHOD FOR PRODUCING CYCLOBUTANE-1,2,3,4-TETRACARBOXYLIC ACID COMPOUND

Title:

METHOD FOR PRODUCING CYCLOBUTANE-1,2,3,4-TETRACARBOXYLIC ACID COMPOUND

Document Type and Number:

Japanese Patent JP2007238460

Kind Code:

A

Abstract:

To provide a method for producing a cyclobutane-1,2,3,4-tetracarboxylic acid compound in high selectivity, enabling the reaction by dispersing in water completely without using an organic solvent as a reaction medium while keeping extremely high photoreaction efficiency and generating little industrial wastes.

The production method uses water as a reaction medium in the photodimerization reaction of a dialkyl fumarate to obtain a cyclobutane-1,2,3,4-tetracarboxylic acid compound.
