| titleOfInvention | Method and column for producing at least one diaryl carbonate and/or arylalkyl carbonate |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to an improved method of producing at least one diaryl carbonate of formula , where R, R' and R" independently denote a hydrogen atom, a straight or branched alkyl with 1-34 carbon atoms, an alkoxy with 1-34 carbon atoms, a cycloalkyl with 5-34 carbon atoms, an alkylaryl with 7-34 carbon atoms, an aryl with 6-34 carbon atoms and a halogen atom, wherein R also denotes a -COO-R"' group in which R'" denotes a hydrogen atom, a straight or branched alkyl with 1-34 carbon atoms, an alkoxy with 1-34 carbon atoms, a cycloalkyl with 5-34 carbon atoms, an alkylaryl with 7-34 carbon atoms and an aryl with 6-34 carbon atoms, and/or an alkylaryl carbonate of formula , where R, R' and R" have values given above, R 1 denotes a straight or branched alkyl with 1-34 carbon atoms, from at least one dialkyl carbonate and at least one aromatic hydroxy compound of formula , where R, R' and R" have values given above, wherein (a) dialkyl carbonate, in the presence of at least one reesterification catalyst, reacts with an aromatic hydroxy compound of formula (III), in at least one reesterification column having at least an enrichment part in the top part of the column and at least one reaction zone below the enrichment part, wherein the enrichment part has at least two sections, (b) vapour collected from the top part of the reesterification column is completely or partially condensed in at least one condenser, where at least one enrichment part of the reesterification column is provided with at least one intermediate condenser, wherein heat released during condensation occurring therein is directly or indirectly returned into the process. The invention also relates to a column for carrying out said method, having at least one inlet opening for dialkyl carbonate and at least one inlet opening for the hydroxy compound, at least one outlet opening for the gaseous end product in the top part of the column which is linked to the condenser and at least one outlet opening for the liquid bottom product in the bottom part of the column, at least one enrichment part in the top part of the column and at least one reaction zone below the enrichment part, wherein the enrichment part has at least two sections, wherein at least one enrichment part is provided with at least intermediate condenser. n EFFECT: invention enables use of one or more intermediate condensers to optimise energy integration. n 14 cl, 3 ex, 3 dwg |
