Abstract
Official abstract text for this publication.
The present invention relates to an improved process for the production of conjugated polyunsaturated fatty acids (PUFA), preferably conjugated linoleic acid (CLA), using finely dispersed heterogeneous metal catalysts on a mesoporous support, in the absence of Hg. The present invention also relates to a method to increase the large microporosity and (optionally) the small mesoporosity of a zeolite, thus obtaining a modified zeolite having a large and highly accessible internal surface.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for preparing conjugated polyunsaturated fatty acids by isomerisation of a nonconjugated PUFA comprising contacting a starting material containing a nonconjugated PUFA with a heterogeneous catalyst containing a finely dispersed catalytic metal supported on a mesoporous zeolite or zeolite-like material having microporous and mesoporous porosity, wherein said heterogenous catalyst has a low Brønsted acidity by the presence of large monovalent alk…
