No. 764,040, filed Sept. 25, 1968, which in turn is a continuation of my United States application Ser. No. 511,989, filed Dec. 6, 1965.
The present invention relates to a new class of gerrnicides.
It is well known that halogenated salicylanilides have germicidal properties. The use of such compounds is described in Angew. Chem., 1955, 67, 145 (D. Jerchel and H. Oberheiden) and J. Pharm. Sci., 1961, 50, 831 (H. Lemaire, C.H. Schrarnm and A. Cahn).
It has now been discovered that the effectiveness of such compounds as gerrnicides can be increased by modifying their molecular structure by replacing at least one of the H atoms attached to C in either or both of the aromatic rings of the salicylanilide residue by a phenoxy or halogenated phenoxy group. It has also been found that the similar introduction of a phenoxy or halogenated phenoxy group into salicylanilide itself results in a useful germicide. As halogen, chlorine and bromine are particularly suitable.
Accordingly, the invention provides a salicylanilide wherein at least one of the H atoms attached to C in either or'both of the aromatic rings of the salicylanilide residue is replaced by a phenoxy or halogenated phenoxy group of from zero to the total number of the remaining H atoms attached to C in said aromatic rings in replaced by halogen.
The compounds where the phenoxy substituent is in th aniline ring of the salicylanilide are preferred.
Another aspect of the invention is a germicidal composition containing a salicylanilide of the invention.
The salicylanilides of the invention have been found to be effective in soap against both gram-positive (Staph. aureus) and gram-negative (E. coli) bacteria. Accordingly, another aspect of the invention is a saponaceous composition containing a salicylanilide of the invention.
It has also been discovered that mixtures of the salicylanilides of the invention with certain well known germicides for use in detergent compositions, namely, 3,4,4'-trichlorocarbanilide (TCC), 3,5,4'-tribromo-salicylanilide (TBS) and 2,2-dihydroxy-3, 5, 6, 3, 6'-hexachloro-diphenylmethane (G 1 1) display synergistic bacteriostatic effect. The invention further includes synergistic bacteriostatic mixtures of the sal icylanilides of the invention with 3,4,4'-trichlorocarbanilide, 3 .5 ,4-tribromosalicylanilide or 2.2 -dihydroxy-3,5,6,3',5.6'- hexachIoro-diphenylmethane. Accordingly, another aspect of the invention is a germicidal composition containing a synergistic bacteriostatic mixture of a salicylanilide of the invention and 3,4,4'-trichlorocarbanilide, 3,5,4-tribromosalicylanilide or 2, 2'-dihydroxy-3. 5, 6, 3', 5, 6-hexachloro-diphenylmethane. A further aspect of the invention is a saponaceous composition containing a synergistic bacteriostatic mixture of a salicylanilide of the invention and 3,4,4-trichlorocarbani- Iide, 3,5,4'-tribromosalicylanilide or 2,2-dihydroxy-3.5,6,3. 5Z6-hexachloro-diphenylmethane.
The salicylanilides of the invention can be prepared by a variety of methods. For example, one method is the condensation of a haloaminodiphenylether (A) with a halogen-substituted salicylic acid (B), A and B being prepared by standard methods for the preparation of such compounds; another method is the direct halogenation of a phenoxy salicylanilide.
EXAMPLE 1.

The solution on cooling deposited 1.6 g. (51 Percent) of 3,5,3'-trichloro-6'-(pchlorophenoxy)-salicyanilide which was recrystallized from a benzene-petroleum ether mixture to give crystals of m.p. 195-196 C.
