Reactions of 2,2-Dimethyl-1,3-propanediol (cas 126-30-7) with zeolites: Correlation of selectivity with acidity

Add time:09/24/2019 Source:sciencedirect.com
The gas phase reaction of 2,2-dimethyl-1,3-propandiol over ion (alkali) exchanged zeolites gives 2-methyl-propanal (I) (cleavage product), 2-methyl-butanal (II) (rearrangement product) and traces of 3,3-dimethyl-oxetane (cyclisation). The selectivities to (I) and (II) correlated apparently with the acidity of the different zeolites as determined by temperature programmed desorption of pyridine. No simple correlation was observed with the desorption temperature of ammonia. It is suggested, that strong acid sites in a basic environment are responsible for the formation of (I), whereas weaker acid sites catalyze the rearrangement to (II).
