Title: Improvements in chlorhydroxyquinoline and the production thereof
Inventor: CAMPBELL PATRICK JOSEPH
IPC: C07D215/28
Filed: 1960-02-24
Abstract: The invention comprises chlorhydroxyquinoline consisting of 57-74% by weight of 5,7-dichlor-8-hydroxyquinoline, 23-40% 5-monochlor-8-hydroxyquinoline, and 0-3% 7-monochlor-8-hydroxyquinoline; and its preparation by the action of sulphuryl chloride on 8-hydroxyquinoline in glacial acetic acid at a temperature no greater than the reflux temperature, and separation of the product.  It is preferred to use a weight of sulphuryl chloride 1 1/4 to 3 times that of 8-hydroxyquinoline, to effect chlorination at 35-60 DEG C., for example agitating over 3/4 -3 hours, to arrest reaction by rapid cooling by, for example, running into distilled water, and finally to effect separation of the product by reducing the acidity, for example to pH 6 with ammonia, followed by centrifuging and washing.  The defined mixture has unexpected biological activity.ALSO:A chlorhydroxyquinoline mixture consisting of 57-74% by weight of 5,7-dichlor-8-hydroxyquinoline, 23-40% 5-monochlor-8-hydroxyquinoline and 0-3% 7-monochlor-8-hydroxyquinoline has antibacterial, antiamoebic and antifungal activity.
