Comments on the use of 2-methylbut-3-yn-2-ol decomposition as a probe reaction for the potential reactivity Mg-Al hydrotalcites as base catalysts

Mg:Al hydrotalcites (Mg:Al ratios 3:1, 3:2 and 4:1) have been characterised using the decomposition of 2-methylbut-3-yn-2-ol as a probe reaction for the acidic/basic properties. The hydrotalcites were used either as synthesised, or following calcination at 225 and 450 °C. All gave almost exclusively...
