Method for producing alkali metal catalyst and use thereof for the side-chain alklation of alkyl aromatics
摘要:
The invention relates to a process for the preparation of an alkali metal catalyst by mixing an alkali metal with pulverulent, solid potassium carbonate as support, wherein the potassium carbonate has a specific surface area of at least 0.3 m2/g, and to the use thereof for the side-chain alkylation of alkylbenzenes.
