摘要
邻氨基苯甲酸在-5～-2C於氟化氢中直接重氮化,后将重氮盐於80C分解,产生邻氟苯甲酸。采用直接重氮化和分解氟代,简化了操作程序,缩短了工艺流程。
Direct diazotisation of anthranilic acid at —5～—2℃ in the presence of hydrogen fluoride, followed by decomposition of the diazonium fluoride at 80℃,gave o-fluorobenzoic acid. The operating procedure was simplified and technological procedure shortened ,by using the direct diazotisation and decomposition-fluorotion.
