Process for obtaining beta hydroxy and/or beta unsaturated carbonyl compounds |
摘要 |
Preparation of beta -hydroxy carbonyl compounds and/or alpha , beta -unsaturated carbonyl compounds involves contacting at least one aldehyde or ketone with a solid magnesium-aluminium double hydroxide catalyst of formula (I). x = 0.20-0.33; n = < 1. Also claimed is catalyst (I) for use in the above process, where (I) has been obtained by hydration of the double oxide Mg1-xAlxO1+x (itself obtained by calcination of hydrotalcite) in the absence of carbon dioxide followed by rinsing with a water-miscible solvent (preferably acetone).
