实验步骤: 16.6 g of an equimolar mixture of cis/trans-4-hydroxymethyl-2-propyl-1,3-dioxolane and 5-hydroxy-2-propyl-1,3-dioxane were combined with 100 g of glycerin (glycerol) in a 300 mL stainless steel autoclave. 2.0 g of 5% Pd/C catalyst were added and the autoclave was sealed. The reactor was heated to 200° C. The reactor was then brought to an operating pressure of 6.89 MPa and stirring commenced at 750 rpm. Pressure was maintained through the duration of the experiment. After 2 h, the autoclave was cooled and remaining gas vented. The autoclave was opened, its contents filtered, and the filtrate analyzed by gas chromatography (GC). 76% conversion of the acetal mixture was observed. Upon analysis of the results, the mixture was found to demonstrate 26.1% selectivity to 2-butoxy-1,3-propanediol, 71.7% 3-butoxy-1,2-propanediol, and the balance n-butanol. the autoclave was sealed Pressure was maintained through the duration of the experiment the autoclave was cooled its contents filtered
