摘要： The invention relates to a method for continually producing 1,3-dioxolan-2-ones such as ethylene carbonate or propylene carbonate by reacting a corresponding oxirane with carbon dioxide in liquid phase in the presence of a catalyst. The reaction is carried out in a two-part reactor. In the first part of the reactor, the reaction is carried out with back-mixing until a conversion rate of oxirane II of at least 80 % has been reached. In the second part, the reaction is completed under conditions without back-mixing, the carbon dioxide being guided to the oxirane II in a counterflow throughout the reactor.

摘要： Disclosed is a process for reducing organic compounds having CC, CO, CN or NN double bonds, which comprises reacting the organic compounds with hydrocarbons in the presence of carbon at 150-500.degree.C. This process which is inexpensive and overcomes the disadvantages of the catalytic reduction processes, is widely applicable. For instance, alkenes can be reduced to alkanes; azo compounds, hydrazones, oximes or Schiff's bases to amines; aldehydes/ketones or derivatives thereof, such as ketals or thioketals, to hydrocarbons; and condensed aromatic hydrocarbons to dehydro compounds.

摘要： Disclosed is a process for reductively dehalogenating aliphatic, cycloaliphatic, aromatic or araliphatic halogen compounds in which no less than one halogen atom is bounded to a carbon atom. This process which can be carried out easily in industry, even on a large scale, and is free of the disadvantages of the prior art processes, comprises reacting the halogen compounds with hydrocarbons in the presence of carbon in the liquid phase at from 100 to 450.degree.C with formation of hydrogen halides. This process is particularly useful for the selective reduction of aromatic or hetaromatic acyl halides, in particular bromides or chlorides, to aldehydes.

摘要： In the process for the continuous preparation of alkyl esters of (meth)acrylic acid by reacting (meth)acrylic acid with monohydric alkanols having from 1 to 8 carbon atoms in the presence of an acid esterification catalyst in a reaction zone, there is discharged from the reaction zone a product mixture which comprises the alkyl (meth)acrylate formed, the catalyst and the by-products formed during the course of the esterification having boiling points higher than that of the alkyl (meth)acrylate, and from which the alkyl (meth)acrylate is separated by distillation in a separation zone. The product mixture discharged from the reaction zone is fed to a rectification unit (I), in this unit the product mixture discharged is separatedby rectification into at least one product (I) comprising the alkyl ester of (meth)acrylic acid and a product (II) comprising the catalyst, the product (I) is fed to a further rectification unit (II) and in this the alkyl ester of (meth)acrylic acid is separated off by rectification.
