Preparation of acrylic acid derivatives from alpha or beta-hydroxy carboxylic acids |
| abstract |
The invention is directed to a process for the preparation of alphabeta,-unsaturated acids, esters and amides from alpha or beta-hydroxycarboxylic acids or esters or precursors in high yields and high selectivity. The alpha,beta-unsaturated acids or esters are optionally prepared in the presence of specific dehydration and/or esterification catalysts. The alpha,beta-unsaturated amides or substituted amides are prepared optionally in the presence of a dehydration and/or amidation catalyst. The source of alpha or beta-hydroxycarboxylic acids or precusor is preferably from a renewable resource. The precursor is defined herein. |
