Definitions

  • the vinyl phosphates such as dimethyl Z-carbomethoxy-l-methylvinyl phosphate and dimethyl 2,2-dichloroyinyl phosphate, and related phosphonates and phosphinates, constitute a general class of highly effective insecticides.
  • applications-as in baits, dusts or the like-these insecticides must be used in the form of dry formulations wherein they are impregnated upon solid materials.
  • Such formulations have been prepared, and it has been found that these insecticides tend to be unstable when formulated in this manner. The reason for this instability has not been determined with certainty, but it is believed to involve in substantial part hydrolysis of the insecticides. It does not appear from examination of a variety of typical members of these insecticides impregnated upon a variety of solid carrier materials that the instability of the insecticides is due to the nature of the carrier material, but that the instability occurs irrespective of the carrier material.
  • insecticides which have been found to exhibit instability in dry formulations on solid carriers, and which are stabilized according to this invention, have the formula:
  • R represents hydrocarbon or substituted hydrocarbon
  • R represents hydrogen, halogen or one of the groups represented by R
  • R" represents halogen, one of the groups represented by R or a functional organic group
  • n is 0, l or 2
  • the halogen be middle halogen-that is, bromine or chlorine.
  • the organic groups represented by the symbols, R and R preferably are low molecular Weight hydrocarbon or substituted hydrocarbon groups, for example, containing from one to ten carbon atoms each. They may be aliphatic, cycloaliphatic, aromatic or of mixed structure. When aliphatic, they may be either straight-chain or branched-chain in configuration.

  • n 2that is, in the phosphate insecticidesthe two symbols, R, may together represent a divalent hydrocarbon group, each of the symbols representing one valence bond thereof.
  • R may represent such a divalent hydrocarbon group.
  • the substituted hydrocarbon groups represented by R and R are those of the above-mentioned hydrocarbon groups which are substituted by one or more non-hydro carbon substituents.
  • the preferred substituents are mid- :dle halogen, the nitro group and amine groups represented by the formula:
  • non-hydrocarbon groups include monohaloalkyl groups, such as the chloromethyl and bromomethyl groups, the 2-chloroethyl, l-bromopropyl, 3-chloropropyl and the like; polyhaloalkyl groups, such as the dichloromethyl, tribromomethyl, 1,2-dichlor0- ethyl, 2,2 dibromoethyl, 3,3 dichloro 2 bromo'propyl groups, and the like; nitroalkyl groups such as the 2- nitroethyl group; halo-substituted aromatic groups such as the various isomeric chloroand bromophenyl groups, the various isomeric polyhalophenyl groups, such as the 2,6-dichlorophenyl group, the 3,5-dibromophenyl group and the like; amino-substituted groups, such as the 2- aminoethyl group, the Z-dimethylandnoethyl group

  • each R is lower hydrocarbonparticularly alkyl of up to seven carbon atoms, aryl of up to ten carbon atoms or aralkyl of up to 10 carbon atoms, particularly the phenyl or benzyl group;
  • R bonded to the alpha carbon atom is hydrogen or one of the groups represented by R and (a) R bonded to the beta carbon atom is middle halogen and R" is middle halogen;
  • R bonded to the beta carbon atom is hydrogen, middle halogen or one of the preferred groups represented by R, and R is a group of the formula H a.

  • phenol itself is a suitable stabilizer, as are other mononucle'ar phenols such as alkyl-substituted phenols.
  • the stabilizer suitably may be a polynuclear phenol, such as alph and beta-naphthols.
  • Polyphenols such as hydroquinone and 2,2-bis(p-hydroxyphenyl)propane, also are suitable.
  • Those phenols which are known to be antioxidants are suitable.
  • kryptophenols--phenols substituted at one or both of the carbon atoms of the aromatic ring in position ortho to the carbon atom thereof to which is bonded the phenolic hydroxyl group-in which a stereo-chemical efiect shields or protects the phenolic hydroxyl group.
  • These also include the polyphenols with ortho and para hydroxyl groupswhich can undergo hydroquinone-quinone transformation. It must be noted, however, that the property of being an antioxidant is not essential to the utility of a phenol as a stabilizer in the present invention, since phenol itself, and beta-naphthol, which are not considered to be antioxidants, are quite suitable as stabilizers in the present invention.
  • phenols which may be used to stabilize these insecticides include catechol, pyrogallol, resorcinol, phloroglucinol, sesamol, B-phenylisocoumarone, the tocopherols, p-aminophenol, phenol ethers, 2,6-di-tert-butylphenol, 2,6-di-tert-butyl-alpha-dimethylamino-p-cresols, the cresols, 4,4-bis(2,6-di-tertbutylphenol), 4,4 methylene bis(6-tent butyl-o-cresol), 2,6-di-tert-butyl-alpha-methoxy-p-creso1, 2,6-di-tert-butylp-cresol, 2,2-methylenebis( t-methyl-6-tert-butylphenol), butylated hydroxyanisoles, propyl gallate, butyl ated hydroxytoluenes,

  • the preferred carrier materials for use with those insecticides defined in Formula I, column 3 are the montm-orillonite clays, particularlythat known as Pikes Peak clay.
  • Sand, sugar, pyrophyllites, particularly that known as Pyrax ABB and talc, particularly that known as Emtal 23A, are preferred carriers foruse with those insecticides defined in Formula II, column 3. 7
  • the phenol stabilizer is incorporated in the formulation in any manner, which will enable it to be intimately contactedwith the insecticide therein.
  • the phenol may be dissolved in the insecticide, or vice versa, depending upon the relative concentrations and solubilities of the two materials.
  • it may be merely intimately mixed in the already formed mixture of carrier and insecticide.
  • the phenol, or the phenol and insecticide together can be dissolved in a suitable solvent, and the solution mixed with the carrier or the carrier-insecticide mixture, as the case may be.
  • the solvent then may be removed wholly, or in part; or in some cases, it may be desirable to include the solvent in the formulation.
