摘要: The invention provides a process for preparing diaryl carbonates from dialkyl carbonates and aromatic hydroxyl compounds using at least two reaction columns, a process section for recovering the dialkyl carbonate used in the reaction and for removing the alcohol of reaction, one or more process steps for removing the by-products obtained in the process which have a boiling point between that of the dialkyl carbonate and that of the alkyl aryl carbonate formed during the preparation of the diaryl carbonate, and a process step for further purification of the diaryl carbonate obtained from the reaction columns.

摘要: The invention relates to a method for producing lithium-transition metal mixtures of general formula Lix(M1yM21-y)nOnz, wherein M1 represents nickel, cobalt or manganese, M2 represents chromium, cobalt, iron, manganese, molybdenum or aluminium, and is different from M1, n is 2 if M1 represents manganese and is 1 otherwise, x is comprised between 0.9 and 1.2, y is comprised between 0.5 and 1.0 and z is comprised between 1.9 and 2.1. According to the inventive method, an intimate mixture composed of transition metal compounds containing oxygen and of a lithium compound containing oxygen is calcinated, said mixture being obtained by processing a solid powder transition metal compound with a solution of said lithium compound, and then drying. At least the M1 compound is used in powder form having a specific surface of at least 20 m2/g (BET) and calcination is carried out in a fluidised bed.
