Abstract: Processes for conversion of propylene polyol feed into useful petrochemical products, including olefin monomers, are described. Such processes comprise: adding a feed stream comprising one or more propylene polyols to a dehydration cleavage reaction zone in the presence of a dehydration cleavage catalyst and reacting at a pressure and temperature sufficient to form a product stream comprising propionaldehyde, a dioxolane component, and a dioxane component; and adding the product stream and hydrogen to a dehydration reaction zone in the presence of a hydrogenation catalyst to form and reacting at a pressure and temperature sufficient to form a second product stream comprising a propanol component. The second product can be added to a dehydration reaction zone in the presence of a dehydration catalyst and reacted at a pressure and temperature sufficient to form a third product stream comprising propylene.

Abstract: A heterogeneous catalyst for substrate-directed hydrogenation includes bimetallic nanoparticles of M1-M2, wherein M1 is a noble metal and M2 is a first-row transition metal. The bimetallic nanoparticles are on a substrate and atoms of both the noble metal and the first-row transition metal are distributed across surfaces of the bimetallic nanoparticles. The heterogeneous catalyst may be produced by providing M1-M2 bimetallic nanoparticles on a substrate to produce an intermediate composition, and performing a reduction process on the intermediate composition such that atoms of both the noble metal (M1) and the first-row transition metal (M2) are distributed across surfaces of the bimetallic nanoparticles and thereby form the heterogeneous catalyst. The catalyst may be used for performing directed hydrogenation of a substrate.

Abstract: The present invention relates to a particularly economic overall method for producing menthol, specifically for producing optically active, essentially enantiomerically and diastereomerically pure L-menthol and racemic menthol, starting from the starting material citral which is available inexpensively on an industrial scale. The method has the following steps a.1) catalytic hydrogenation of neral and/or geranial to give citronellal, b.1) cyclization of citronellal to isopulegol in the presence of an acidic catalyst, c.1) purification of isopulegol by crystallization and d.1) catalytic hydrogenation of isopulegol to give menthol.

Abstract: A process for simultaneously hydrating and oligomerizing a hydrocarbon feed comprising mixed olefins incudes the steps of: (a) introducing the hydrocarbon feed in the presence of water into a fixed bed; (b) contacting the hydrocarbon feed with a catalyst within said fixed bed reactor, where the catalyst is of the type that hydrates the mixed olefins to form mixed alcohols and oligomerizes at least a portion of the mixed olefins into oligomers to produce a first product stream that includes an organic phase and an aqueous phase; (c) introducing the first product stream into a first separator which separates the organic phase from the aqueous phase; (d) introducing the separated organic phase into a second separator which separates unreacted olefins from mixed alcohols and one or more oligomers which comprise a final product stream; and (e) introducing the separated aqueous phase into a third separator which separates an alcohol-water azeotrope component from water.
