Selective hydrogenation of 2-pentenal using highly dispersed Pt catalysts supported on ZnSnAl mixed metal oxides derived from layered double hydroxides

A highly dispersed Pt catalyst supported on ZnSnAl mixed metal oxides (MMO), with Pt in single-atom and small nanoclusters, was produced by the induction of lattice-confined Sn sites in layered double hydroxides (LDHs) and used in the selective hydrogenation of 2-pentenal. Compared with the Pt/Al2O3, Pt-SnOx/Al2O3 and MgSnAl-MMO supported Pt catalysts, the optimized ZnSnAl-MMO supported Pt catalyst gave a higher selectivity to 2-pentenol (82.2%) at 28.5% conversion of 2-pentenal. Based on catalytic evaluation results and catalyst characterization with XRD, Pyridine-IR, H2-TPR, XPS, and HAADF-STEM, it was found that the combined effects of Sn and Zn species promoted the performance of the Pt catalyst by favoring the activation of the CO bond. In addition, due to the size effect and electronic effect on the Pt species, the highly dispersed Pt induced by the lattice-confined Sn sites in ZnSnAl-LDH enhanced the catalytic activity of Pt/Zn(1Sn)(Al)O/Al2O3 by 2.7 times compared with Pt-SnOx/Zn(Al)O/Al2O3.

Combined synergetic and steric effects for highly selective hydrogenation of unsaturated aldehyde

Enhancing the selectivity to unsaturated alcohols for the hydrogenation of unsaturated aldehydes is of great importance and challenge. Herein, Pt-SnOx@ZIF-8 catalysts with combined synergetic and steric effects were designed for the hydrogenation of 2-pentenal. The selectivity to unsaturated alcohol was enhanced from 4.3% to 61.5% by the synergetic effect between SnOx and Pt active sites and was further enhanced to 80.9% by the steric effect of ZIF-8. In situ FTIR was used to investigate the surface reaction mode over the present catalysts. The results showed that SnOx acted as electrophilic sites for the adsorption and activation of the C[dbnd]O bond and the apertures of ZIF-8 oriented the C[dbnd]O adsorption on the active sites.

METHOD FOR PRODUCING UNSATURATED ALCOHOL

PROBLEM TO BE SOLVED: To provide a method for producing an unsaturated alcohol that uses an unsaturated carbonyl compound as a raw material and can produce an unsaturated alcohol in which only the carbonyl bond of the unsaturated carbonyl compound is selectively reduced with excellent reaction rate, high selectivity and high yield. SOLUTION: The process for producing an unsaturated alcohol includes a step of allowing the reductive reaction of a 3C or more unsaturated carbonyl compound having one or more carbon-carbon unsaturated bonds in the molecule with hydrogen to proceed in the presence of a catalyst comprising at least one kind of metal selected from the group consisting of cobalt, nickel, copper, zinc, ruthenium, rhodium, palladium, silver, osmium, iridium and platinum and at least one kind of metal selected from the group consisting of vanadium, chromium, manganese, iron, molybdenum, tungsten and rhenium to produce a corresponding unsaturated alcohol.

Rapid synthesis of unsaturated alcohols under mild conditions by highly selective hydrogenation

Ir-ReOx/SiO2 acted as a highly active and selective heterogeneous catalyst for the hydrogenation of unsaturated aldehydes to unsaturated alcohols in water at low H2 pressure (0.8 MPa) and low temperature (303 K). The catalysis is derived from the synergy between Ir metal and ReOx.

The present invention provides a commercially viable process for the preparation of highly pure and optically active L-(+)-lactic acid and S-(-)-methyl lactate, in high yield, obtained from esterification of aqueous crude lactic acid solution produced by sugar cane juice fermentation broth and methanol in continuous counter current trickle phase approach or in continuous counter current bubble column manner, using stabilizers and the methyl lactate so obtained is recovered and followed by purification of reasonably pure methyl lactate using reagent mixture such as sodium bi-carbonate, mono-ethanolamine or di-ethanolamine, urea or sodium-bicarbonate, mono-ethanolamine or di-ethanolamine, thiourea to reduce the impurity of dimethyl ester of dicarboxylic such as dimethyl oxalate or di-methyl succinate or methyl ester of mono-carboxylic acid such as methyl pyruvate present as an impurity, so as to get highly pure S-(-)-methyl lactate followed by hydrolyzing highly pure S-(-)-methyl lactate using highly pure lactic acid as a catalyst, using highly pure water as the hydrolysis media and by using pre-treated activated carbon with dilute L-(+)-lactic acid, in batch or continuous mode. This very high pure S-(-)-methyl lactate constitutes an important product having interesting possibilities of application at an industrial level, in pharmaceuticals. Highly pure L-(+)-lactic acid thus obtained is used as an acidulant, as a food additive, for pharmaceutical applications ,a monomer for making poly-lactic acid ,as a monomer to prepare biodegradable polymer which are useful for manufacturing bags, application films, in the field of sanitary field, and has medical applications.
