Patent GB-648773-A (GB)
Title: Pest control composition
IPC: A01N31/08
Filed: 1947-11-26
Abstract: A pest control compound is prepared by reacting at least one halogenated mono-hydroxy-benzene having halogen as the sole additional substituent on the ring, with at least one aliphatic primary unsubstituted amine having an alkyl chain length of 6 to 18 carbon atoms.  Specified halogeno-phenols are pentachlorphenol, 2,4,5-trichlorphenol, and 2,3,4,6-tetra-chlorphenol.  Specified amines are dodecylamine, "coconut" amine, and "octadecenylamine," a commercial product containing octadecenyl and octadecadienyl amines. The Specification as open to inspection under Sect. 91 comprises also the employment of 2-chloro- or 2-bromo-4-phenylphenol or 2,21-dihydroxy - 5,51 - dichlorodiphenyl methane instead of the above-defined phenols, or octadecyldimethylamine instead of the above-defined amines.  This subject-matter does not appear in the Specification as accepted.ALSO:A pest control composition which may be included in coating compositions is prepared by reacting at least one halogenated monohydroxy-benzene having halogen as the sole additional substituent on the ring, with at least one aliphatic primary unsubstituted amine having an alkyl chain length of 6 to 18 carbon atoms.  Specified halogene-phenols are pentachlorphenol, 2,4,5-tri-chlorophenol, and 2,3,4,6-tetra-chlorphenol.  Specified amines are dodecylamine, "coconut" amine, and "octadecenylamine," a commercial product containing octadecenyl hexadecenyl and octadecadionyl amines.  The composition may be dissolved in solvents such as mineral spirits, xylol, toluol, isophorone, ethyl alcohol, butyl alcohol, and diacetone alcohol, or admixed with paraffin wax, aluminium stearate, chlorinated paraffins, casein composition, sizings and leather dressings.  The compositions may also be dispensed in water with the aid of emulsifying agents such as petroleum sulphonates.  The compositions may be incorporated in paints and varnishes, particularly anti-fouling paints.  The Specification as open to inspection under Sect. 91 comprises also the employment of 2 - chloro - or 2 - bromo - 4 - phenylphenol, or 2,21 - dihydroxy - 5,51 - dichlorodiphenyl methane instead of the above defined phenols, or octadecyldimethylamine instead of the above defined amines.

Specified halogenophenols are pentachlorphenol, 2,4,5, trichlorphenol, and 2,3,4,6 tetra-chlorphenol.  Specified amines are dodecylamine, "cocoa-nut" amine, and "octadecenylamine" a commercial product containing octadecenyl hexadecenyl and octadecadienyl amines.  The composition may be dissolved in solvents such as mineral spirits, xylol, toluol, isophorone, ethyl alcohol, butyl alcohol, and diacetone alcohol, or admixed with paraffin wax, aluminium stearate, chlorinated paraffins, casein compositions, paint and varnish coating materials, sizings, and leather dressings.  The compositions may also be dispersed in water with the aid of emulsifying agents such as petroleum sulphonates.  The compositions may be incorporated in paints and varnishes, particularly anti-fouling paints.  They may also be employed in the mildewproofing of materials.
