摘要:
The present invention relates to a process for continuously preparing diaryl carbonates from dialkyl carbonates and at least one monohydroxyl compound in the presence of catalysts, and to the use thereof for preparation of polycarbonates. The alkylene glycol obtained in the preparation of the dialkyl carbonate used is recycled by oxidative carbonylation with carbon monoxide in the presence of a catalyst to give the cyclic alkylene carbonate which is in turn converted to the dialkyl carbonate. More particularly, the process utilizes the alkylene glycol obtained for the diphenyl carbonate preparation process (DPC process).
摘要:
The present invention relates to a continuous process for purifying a dialkyl carbonate/alkyl alcohol mixture in the preparation of dialkyl carbonate by catalysed transesterification of a cyclic alkylene carbonate (e.g. ethylene carbonate or propylene carbonate) with alkyl alcohols. For the increase in the product quality of the dialkyl carbonate, the selection of the operating parameters of the dialkyl carbonate purification column are crucial, in order to reduce the formation of unwanted by-products such as alkoxy alcohols and aliphatic carbonate ethers.
