The present invention relates to a process for decomposing an aromatic acylated compound·HF-BF₃ complex in preparing an aromatic acylated compound by decomposing an aromatic acylated compound·HF-BF₃ complex obtained by reacting an aromatic compound with an acylating agent in the presence of HF-BF₃ as a catalyst, which comprises subjecting the aromatic acylated compound·HF-BF₃ complex to thermal decomposition in the presence of at least one aromatic hydrocarbon (A.H.) selected from benzene, toluene and chlorobenzene and at least one saturated aliphatic hydrocarbon (S.H.) selected from pentane, hexane and cyclohexane, as a decomposing agent.
本发明涉及一种在制备芳香族酰化化合物时分解芳香族酰化化合物-HF-BF₃ 复合物的工艺,该工艺通过在 HF-BF₃ 作为催化剂存在下使芳香族化合物与酰化剂反应得到的芳香族酰化化合物-HF-BF₃ 复合物进行分解,该工艺包括在至少一种选自苯、
甲苯和
氯苯的
芳香烃 (A. H.) 和至少一种选自
戊烷、己烷和
环己烷的饱和脂肪烃 (S.H.) 存在下使芳香族酰化化合物-HF-BF₃ 复合物进行热分解。H.)和至少一种选自
戊烷、己烷和
