摘要： Dialkyl carbonates can be prepared in a continuous manner by transesterification of ethylene carbonate or propylene carbonate with alcohols in the presence of a catalyst in a column equipped with packing or baffles, by passing the reactants in countercurrent such that the ethylene carbonate or propylene carbonate are metered into the upper part of the column and the alcohol is metered into the lower part of the column and the catalyst is arranged as a fixed bed in the column or is also metered into the upper part of the column in solution or suspension, the dialkyl carbonate formed, if appropriate as a mixture with alcohol, being removed at the top of the column and the ethylene glycol or propylene glycol formed from the ethylene carbonate or propylene carbonate being removed at the foot of the column, if appropriate together with the catalyst.

摘要： The invention relates to a method for the thermal decarboxylation of dicarboxylic acids, in particular to 3,4-ethylene dioxythiophene-2,5-dicarboxylic acid as an educt. According to said method the educt is used in solid form and/or the reaction is carried out in the presence of a plurality of fluidised bed bodies. No solvents are used in the reaction and the decarboxylation product that is formed during the reaction is carried away from the reaction zone in gaseous form.
