    摘要： The present invention relates to a process for the production of alkanesulfonic acid. More particularly, the present invention relates to a process for the production of alkanesulfonic acid from alkyl mercaptan effluents generated in chemical industries. The process of the invention comprises the oxidation of the entire alkyl mercaptan generated as an effluent in the chemical industries to serve two concomitant purposes: (1) complete removal of obnoxious odour, and (2) value addition by the production of alkanesulfonic acids selectively in quantitative yields.

    摘要： Diaryl carbonate and an aromatic hydroxy compound are simultaneously separated from a crude reaction mixture for producing diaryl carbonates by oxidative carbonylation of the aromatic hydroxy compound and containing the diaryl carbonate and excess hydroxy compound together with the catalyst system, consisting of a noble-metal catalyst, co-catalyst, quaternary salt and a base. The crude reaction mixture is mixed with a covalent aprotic extraction agent, a phase separation is carried out into a donor phase containing the catalyst system and a recipient phase containing the diaryl carbonate and the hydroxy compound in concentrated form, and the diaryl carbonate and the hydroxy compound are isolated from the recipient phase.

    摘要： Isopropylphenyl esters are converted to di- or trihydric phenols via a novel autoxidation of the esters at high conversion rates to the corresponding hydroperoxyisopropylphenyl esters in the presence of a catalyst combination comprising at least two members selected from the group consisting of (i) a metal phthalocyanine; (ii) a di-tertiary alkyl peroxide; and (iii) a tertiary alkyl hydroperoxide.Rearrangement of the hydroperoxyisopropylphenyl esters to the corresponding hydroxyphenyl esters and the hydrolysis of the latter compounds provides the phenols in overall yields (from the starting esters) heretofore not obtainable. Novel bis(hydroperoxyisopropylphenyl)carbonates are described which are attractive intermediates for the intermediate bisphenol carbonate or the final hydroquinone hydrolysis product.

    摘要： Process for splitting primary alkylaromatic hydroperoxides to yield phenolic products is described which consists of reacting the hydroperoxide with a catalytic amount of a compound with an acid reaction, in an organic solvent medium, the characteristic feature being that the splitting medium is a mixture consisting of:A. at least one solvent chosen from the group of aprotic polar solvents formed by polymethylene-sulphones, alkylene glycol carbonates which contain 2 to 4 carbon atoms (in the alkylene portion) and aliphatic or aromatic nitriles, andB. at least one hydroxylic solvent taken from the group formed by aliphatic alcohols containing 1 to 3 carbon atoms and alkylene glycols containing up to 4 carbon atoms.
