Patent number: 5731440Abstract: An industrially advantageous process for producing 5,7-dichloro-4-hydroxyquinoline (DCHQ) useful as an intermediate for agrohorticultural bactericides. The process comprises (i) hydrolyzing 3-cyano- or 3-ethoxycarbonyl-5,7-dichloro-4-hydroxyquinoline into 5,7-dichloro-3-carboxy-4-hydroxyquinoline (DCQA) in the presence of hydrochloric, sulfuric or phosphoric acid and (ii) decarboxylating the formed DCQA into DCHQ in the presence of sulfuric or phosphoric acid. In particular, this process comprises continuously conducting the hydrolysis of 5,7-dichloro-3-ethoxycarbonyl-4-hydroxyquinoline and the decarboxylation of the hydrolyzate in the presence of sulfuric acid having a specified concentration. The invention also relates to a process for producing DCQA by hydrolyzing 3-cyano- or 3-ethoxycarbonyl-5,7-dichloro-4-hydroxyquinoline in the presence of hydrochloric, sulfuric or phosphoric acid and a process for producing DCHQ by decarboxylating DCQA in the presence of sulfuric or phosphoric acid.Type: GrantFiled: September 3, 1996Date of Patent: March 24, 1998Assignees: Ishihara Sangyo Kaisha Ltd., Chemipro Kasei Kaisha, Ltd.Inventors: Hiroshi Yoshizawa, Motohiko Hamaguchi, Tomizo Fujino
