Abstract: Disclosed is a method for producing organic disulphide by oxidation of the corresponding thiol with sulphur disolved in organic disulphide using an amine as a catalyst in a reaction column (K). The thiol used is a crude thiol flow from catalytic reaction of the corresponding primary alcohol with hydrogen sulphide and the bases of the reaction column (K) are temperable.

Abstract: A method for complexing 2-6C carboxylic acids (I) involves bringing an acid phase containing (I) into contact with a phase containing amine(s) with boiling point(s) higher than that of (I) as complexing agent(s), to give a complex with a b.pt. higher than that of some of the components in the acid phase. Independent claims are also included for: (i) a method for isolating (I) by treating a gaseous carboxylic acid phase with a liquid complexing phase as above, in which (a) at least some of the components other than (I) in the acid phase are separated as residual gas by heating the complex to a separation temperature at which the complex is still liquid and (b) at least part of the acid (I) is separated as gas in a temperature range within which the complex undergoes cleavage and the complexing phase is liquid; (ii) a process for the production of carboxylate esters by esterification of acids (I) isolated by the above method.

Abstract: The invention relates to a method for producing C1-C4 alkylsulfonic chorides and/or C1-C4 alkanesulfonic acids by reacting di(C1-C4) alkyl-disulfides with chlorine and water. The method is characterized in that the mixture of a di(C1-C4) alkyldisulfide and water is treated with chlorine in a column, in a countercurrent.

Abstract: The invention relates to a method for producing alkyl(meth)acrylate by continuous reaction of an aqueous solution containing (meth)acrylic acid obtained directly from gas-phase oxidation by reacting with a straight-chain or branched alkanol with 1 to 6 C atoms or a mixture of two or more thereof in the presence of an esterification catalyst. The inventive method is characterized in that alkanol is introduced into aqueous solution containing (meth)acrylic acid in the form of a gas.

Abstract: Production of esters by catalyzed reaction of carboxylic acid (or ester) with alcohol in reaction column(s) comprises: (i) feeding acid (or ester) and alcohol into the column spatially separate from each other depending on their boiling points; (ii) formation of an ester by countercurrent reaction at specific temperature and pressure; and (iii) removal of water of reaction from the column as vapor.
