Abstract: The present invention relates to the industrial production of vinylene carbonate (VC) by elimination of hydrogen chloride from chloroethylene glycol carbonate (CGC) with tertiary amines in the absence of relatively large amounts of additional solvent.

Abstract: The present invention relates to the industrial production of vinylene carbonate (VC) by eliminating hydrogen chloride from chloroethylene glycol carbonate (CGC) or solid catalysts in the gas phase, the reaction being carried out over a catalyst bed agitated by thorough mixing.

Abstract: The present invention relates to the technical purification of vinylene carbonate (VC) by means of a simple thermal treatment with organic compounds which possess amidic nitrogen-hydrogen bonds, followed by a distillation and a melt crystallization. In this way VC of ultra-high purity is obtained. The high-purity vinylene carbonate can be stored and transported without stabilizer.

Abstract: The present invention relates to the industrial purification of vinylene carbonate (VC). It was found that it is advantageous to subject the VC to be purified, before the purifying distillation, to a simple thermal treatment with organic compounds which have amidic nitrogen-hydrogen bonds.

Abstract: The aim of the invention is to provide a widely applicable method for the nitration of substituted benzenes.

Abstract: 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.

Abstract: The present invention relates to an improved process for preparing cyclopropanecarboxylic acid and alcohols.

Abstract: The present invention relates to the preparation of nitrobenzoic acids by oxidizing particular nitrotoluenes, nitrobenzyl alcohols, esters and/or ethers in the presence of nitric acid at elevated temperature and elevated pressure. It has been found that the particular nitrotoluenes, nitrobenzyl alcohols, esters and/or ethers may be oxidized particularly reliably and in high yields using nitric acid to the benzoic acid derivatives when they are metered into the nitric acid.

Abstract: 2-Alkyl-3-aryl- or -heteroaryloxaziridines are prepared in a particularly advantageous manner by oxidizing corresponding N-alkyl-aryl- or -heteroarylaldimines with an aromatic percarboxylic acid or a salt thereof in the presence of water, a water-soluble base, and a water-miscible solvent, at temperatures below 30° C. Using this method, it is also possible to obtain novel 2-alkyl-3-aryloxaziridines.
