Abstract: A transfer-hydrogenation process for preparing a carbonyl compound and an alcohol compound comprises the steps of (a) contacting a first carbonyl compound with a first alcohol compound in the presence of a transfer-hydrogenation catalyst in a first reaction zone at conditions effective to form a second carbonyl compound from the first alcohol compound and a second alcohol compound from the first carbonyl compound, and (b) removing the second carbonyl compound from the first reaction zone during step (a). The first carbonyl compound is a saturated aldehyde or ketone, or an α,β-unsaturated aldehyde or ketone. The first alcohol compound is a primary or secondary alcohol. The second alcohol compound is α,β-saturated. The transfer-hydrogenation catalyst includes a Group 8 to 11 metal. This process is useful for preparing and higher value alcohols, such as butanol or 2-ethylhexanol, from the corresponding carbonyl compounds by engaging lower alcohol (C2-C4) feedstocks instead of hydrogen (H2).

Abstract: Disclosed is a process for preparing two esters by reacting an aldehyde with an alcohol in the presence of a ruthenium complex compound as a catalyst. The process is particularly useful for preparing ethyl acetate and n-butyl acetate, isobutyl acetate, or 2-ethylhexyl acetate in high yield by coupling acetaldehyde with n-butanol, i-butanol, or 2-ethylhexanol.

Abstract: The invention relates to a process that integrates the oxidation of toluene to benzoic acid with the production of benzoate plasticizers. Toluene is fed to an oxidation vessel in the presence of oxygen and an oxidation catalyst wherein benzoic acid serves as the solvent for the oxidation. The crude benzoic acid produced is not purified and is then reacted with an alcohol in the presence of an esterification catalyst to produce the crude benzoate ester. The oxidation catalyst, esterification catalyst, and other impurities can be mostly removed from the crude benzoate ester in subsequent washing and filtering steps. The benzoate esters produced through this method can be made in fewer steps with both yields and purities above 80%.
Abstract translation: 本发明涉及一种将苯甲酸氧化成苯甲酸与生产苯甲酸酯增塑剂的方法。 甲苯在氧气和氧化催化剂的存在下进料到氧化容器中，其中苯甲酸用作氧化的溶剂。 所生产的粗苯甲酸不经纯化，然后在醇化催化剂存在下与醇反应生成粗苯甲酸酯。 在随后的洗涤和过滤步骤中，氧化催化剂，酯化催化剂和其它杂质可以主要从粗苯甲酸酯中除去。 通过该方法生产的苯甲酸酯可以以较少的步骤制备，产率和纯度都高于80％。
