Abstract: The oxidative esterification of a homologous series of diols (1,3-propanediol, 2-methyl-1,3-propanediol and 2,2-dimethyl-1,3-propanediol) with methanol has been investigated using titania-supported gold, palladium and gold-palladium catalysts using mol. oxygen. The gold-palladium catalysts showed the highest activity and 1,3-propanediol was the most reactive while the addnl. Me groups decreased the reactivity. However, it is possible to achieve high selectivity to Me 3-hydroxypropionate and 2-methyl-3-hydroxyisobutyrate by mono-oxidations In the experiment, the researchers used Methyl 3-hydroxypropanoate(cas: 6149-41-3Recommanded Product: Methyl 3-hydroxypropanoate)
Methyl 3-hydroxypropanoate(cas: 6149-41-3) belongs to esters with low molecular weight are commonly used as fragrances and found in essential oils and pheromones. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides. Recommanded Product: Methyl 3-hydroxypropanoate
