1,215,165. Quaternary ammonium-hydroxy aryl compounds. CIBA Ltd. 8 Oct., 1968 [16 Oct., 1967], No. 47698/68. Heading C2C. [Also in Divisions A5 and D2] The invention comprises compounds of the Formula I: in which R 1 represents an alkyl C 8-22 radical, R 2 represents a phenyl radical which may be substituted, preferably by alkyl C 1-4 groups or chlorine atoms, R 3 and R 4 each represent a divalent aliphatic C 1-4 radical and A represents an aromatic or heterocyclic radical, containing at most two six-membered rings, which is bound to the oxygen atom via a cyclic carbon atom and which may be substituted. They are prepared by reacting a salt, preferably a halide of the base with a salt, preferably an alkali metal salt of the phenol in organic or in aqueous solution. The following benzyl-bis-(2-hydroxyethyl)-dodecyl ammonium salts are described; thepentachlorophenolate, the 2,4,5,6-tetrachlorophenolate, 2,4,5-trichlorophenolate, 3-methyl-4- chlorophenolate, 3,5 - dimethyl - 4 - chlorophenolate, 2 - (3<SP>1</SP>,5<SP>1</SP>,6<SP>1</SP> - trichloro - 2 - hydroxybenzyl) - 3,5,6 - trichlorophenolate, 8 - quinolinate, 5 - chloro - 8 - quinolinate, 5,7 - dichloro (or dibromo) quinolinate, 5-chloro-7-iodoquinolinate and the 2-naphtholate. 4-Chlorobenzyl - bis - (2 - hydroxyethyl) - dodecyl ammonium pentachlorophenolate and 2,4,5-trichlorophenolate and 4 - methylbenzyl - bis - (2-hydroxyethyl)-dodecyl ammonium 2,4,5-trichlorophenolate are also described. The compounds have disinfectant properties and may be used to treat crude paper. |
