    摘要： A process for preparing acetals from aldehydes and alcohols is carried out by generating a reaction/distillation zone charged with an acidic fixed bed catalyst in a distillation column, feeding the aldehyde and the alcohol to the reaction/distillatlon zone and at least partly converting them to the acetal, heating the column bottom disposed below the reaction/distillation zone in order to at least partly evaporate the bottom's mixture and to establish a defined temperature in the reaction/distillation zone, feeding an extractant into a rectifying section of the column, disposed above the reaction/distillation zone and condensing a product having more than 90% by weight of acetal at the top of the column.

    摘要： The present invention provides a solid acid catalyst that is excellent from the point of toxicity, environment and others, wherein reaction can be progressed effectively with Bronsted acid or Lewis acid catalyst. For example, the benzoylation reaction of alcohol can also be progressed easily, and further, the catalyst can be recovered and recycled easily. The para position of arylbis(perfluoroalkylsulfonyl)methane represented by the general formula [1] (wherein R1 shows a substituted or unsubstituted aryl group, Rf1 and Rf2 are independent to each other and show a perfluoroalkyl group), a pentafluorophenylbis(perfluoroalkylsulfonyl)methane, for example, is supported on a polystyrene resin, and a polystyrene-supported arylbis(perfluoroalkylsulfonyl)methane represented by the general formula [3] (wherein R3 shows a substituted or unsubstituted arylene group, Rf1 and Rf2 are the same as described above) is obtained.

    摘要： A process is disclosed for preparing aldehydes by isomerization of the corresponding unsaturated primary alcohols using a transition metal catalyst system, in an alcoholic solvent and in the presence of an acid. An aldehyde forms by isomerizing an unsaturated primary alcohol under conditions that protect the newly formed aldehyde as a dialkylacetal in situ during the reaction. Protecting the aldehyde as an acetal allows for facile separation of the product from the catalyst as well as effectively driving the reaction toward completion.
