    摘要: Dialkoxybutenes are selectively prepared in high yields by reacting 1,3-butadiene with an alcohol in the presence of oxygen and a catalytically effective amount of solid particulates which comprise a catalytically active phase deposited onto particles of a support therefor, such catalytically active phase comprising at least one Group VIII noble metal first component, at least one tellurium, selenium and/or sulfur second component, and, optionally, at least one bismuth, antimony, copper and/or tin third component.

    摘要: Tin catalysts are provided for epoxidizing olefinic compounds in the presence of organic hydroperoxides, in the liquid phase. These catalysts give good yields of the epoxide and of the alcohol derived from the organic hydroperoxide. They have the formula: RR 'SnCl.sub.2 (I) in which:R represents a wholly aliphatic or cycloaliphatic or aromatic or mixed aliphatic/aromatic, aliphatic/cycloaliphatic or cycloaliphatic/aromatic, inter alia alkylaryl or aralkyl, linear or branched, saturated or unsaturated monovalent hydrocarbon radical, which can optionally carry substituents, such as chlorine atoms, the number of carbon atoms being at most 20,R' represents either a chlorine atom or a monovalent organic radical of the formula: R"--Y (II) in which:Y represents an oxygen atom, or a (--O--O--) group, or a carbonyloxy group (--CO--O--), the radical R" being attached to the carbon atom of the (--CO--O--),R" may be identical or different to R and is as defined under R.

    摘要: The present invention relates to the oxidation, by means of oxygen or a gas containing it, of hydrocarbons to the corresponding carboxylic acids, alcohols and/or ketones or of alcohols and/or ketones to the corresponding carboxylic acids. It consists more precisely in a process for oxidizing hydrocarbon, alcohol and/or ketone, using oxygen or a gas containing it, in liquid phase and in the presence of a catalyst dissolved in the reaction medium, characterized in that the catalyst comprises a soluble manganese compound and at least one soluble chromium compound.

    摘要: The present invention relates to a process for the crystallization of carboxylic acid, more particularly adipic acid, and a process for manufacturing crystalline carboxylic acid, more specifically a process for treating the reaction medium resulting from the direct oxidation of a hydrocarbon into carboxylic acid such as adipic acid, for example. More specifically, the invention relates to the crystallization of adipic acid from an organic solvent, thus removing the organic impurities contained in the said acid and thus optionally facilitating its purification by a crystallization from water.
