Title:
METHOD FOR PRODUCING CYCLICISED COMPOUNDS FROM ORGANIC ACIDS HAVING FROM 4 TO 6 CARBON ATOMS
Document Type and Number:
WIPO Patent Application WO/2011/031023
Kind Code:
A2
Abstract:
The present invention relates to a method for producing cyclicised compounds, and more specifically lactone compounds and heterocyclic compounds comprising oxygen, in high yield, with long-term stability and with high selectivity depending on the metal content of a selective hydrogenation catalyst, by using the catalyst to carry out a hydrogenation reaction on an organic acid, an organic-acid ester or a mixture of an organic acid and organic acid ester having from 4 to 6 carbon atoms.
