摘要： Described herein are solid acid catalysts and the methods for catalytically preparing α,β-unsaturated carboxylic acids and/or esters thereof. In one aspect, a zeolite catalyst may be used. The catalyst may, in certain embodiments, be modified to improve the selectivity and/or conversion of a reaction. For instance, a catalyst may be modified by ion exchange to achieve a desirable acidity profile in order to achieve high level of conversion of reactants and selectivity for desirable products of the catalytic reaction. In another aspect, a variety of feed stocks (e.g., starting compositions) may be used including an α-hydroxycarboxylic acid, an α-hydroxycarboxylic acid ester, a β-hydroxycarboxylic acid, a β-hydroxycarboxylic acid ester, cyclic esters thereof (e.g., lactide), and combinations thereof.

摘要： Disclosed herein are embodiments of a method for making fuels and feedstocks from readily available alcohol starting materials. In some embodiments, the method concerns converting alcohols to carbonyl-containing compounds and then condensing such carbonyl-containing compounds together to form oligomerized species. These oligomerized species can then be reduced using by-products from the conversion of the alcohol. In some embodiments, the method further comprises converting saturated, oligomerized, carbonyl-containing compounds to aliphatic fuels.

摘要： The present application discloses novel amino-sulfide metal catalysts for organic chemical syntheses including hydrogenation (reduction) of unsaturated compounds or dehydrogenation of substrates. The range of hydrogenation substrate compounds includes esters, lactones, oils and fats, resulting in alcohols, diols, and triols as reaction products. The catalysts of current application can be used to catalyze a hydrogenation reaction under solvent free conditions. The present catalysts also allow the hydrogenation to proceed without added base, and it can be used in place of the conventional reduction methods employing hydrides of the main-group elements. Furthermore, the catalysts of the present application can catalyze a dehydrogenation reaction under homogenous and/or acceptorless conditions. As such, the catalysts provided herein can be useful in substantially reducing cost and improving the environmental profile of manufacturing processes for a variety of chemicals.

摘要： Disclosed is a process for the production of higher aldehydes from lower alcohols using a two-stage vapor phase heterogeneous catalyst system. Ethanol feeds afford aldehydes such as butyraldehyde and crotonaldehyde while butanol feeds yield 2-ethylhexanal and 2-ethylhexenal. Higher product selectivities are obtained when the alcohol is first dehydrogenated in the upper catalyst stage followed by aldol condensation of the resulting lower aldehyde to a higher aldehyde.
