Title: Improvements relating to compositions having fungicidal and/or fungistatic properties
IPC: C07F19/00
Filed: 1948-11-05
Abstract: A reaction product having fungicidal and insecticidal properties is prepared by heating a water-insoluble soap of an alkaline earth metal heavy metal or aluminium with an alkaline earth metal salt, heavy metal salt or aluminium salt of a hydroxy quinoline having a hydroxy group or groups attached to the benzene nucleus of the quinoline radical.  Specified soaps are the calcium, barium, magnesium, mercury, lead, cadmium, silver, thallium, manganese, cobalt, nickel, iron, copper, tin or aluminium soaps of caproic, caprylic, capric, lauric, myristic, palmitic, stearic, oleic, linoleic, linolenic, ricinoleic or naphthenic acids or mixtures of such soaps.  Specified hydroxyquinoline salts are the 5-, 6-, 7- or 8-hydroxyquinoline salts of calcium, barium, magnesium, strontium, lead, mercury, manganese, cobalt, nickel, iron, copper, silver, thallium, tin, zinc or aluminium.  The reaction may be effected at 200-550 DEG  F. or higher but below the decomposition temperature of the reactants.  The reaction may be carried out in a reaction medium which may be an excess of the soap or a mixture of the soap with a higher fatty acid. Other specified reaction media are higher fatty acids, linseed oil, chinawood oil, cottonseed oil, soyabean oil, palm oil, coconut oil, sardine oil, tallow, lard, castor oil, dehydrated castor oil, tall oil, rosin, or abietic acid.ALSO:A composition having fungicidal and insecticidal properties is prepared by heating a water insoluble soap of an alkaline earth metal, heavy metal or aluminium with an alkaline earth metal salt, heavy metal salt or aluminium salt of a hydroxy quinoline having a hydroxy group or groups attached to the benzene nucleus of the quinoline radical.
