Title: Insectidical compositions
IPC: A01N65/00

Abstract: Phenols having an unsaturated hydrocarbon side chain of 14 to 28 carbon atoms are chlorinated by bubbling free chlorine gas through the liquid phenol or phenol dissolved in petroleum oil at room temperatures.  Chlorination is considered to take place at the double bond of the hydrocarbon side chain and in the aromatic nucleus and is carried out to any desired extent depending upon the characteristics required in the final product.  The specified phenols are those obtained from the Anacardiaceae family of trees such as cashew nut shell liquid, marking nut shell liquid and Japanese lac; their constituents such as anacardic acid, cardol, anacardol and urushiol; derivatives thereof such as cardanol, the distillate and residue from the steam distillation of cashew nut shell liquid and marking nut shell liquid, hydrocarbon ethers, the polymers and copolymers such as are disclosed in U.S.A. Specifications 2,067,919, 2,128,247 and 2,176,059.  The Specification as open to inspection under Sect. 91 is concerned with chlorinated phenols of the above type which have been sulphonated for various uses such as wetting agents and detergents. This subject-matter does not appear in the Specification as accepted.ALSO:The Specification as open to inspection under Sect. 91 describes rubber-like products obtained by mixing aldehydes such as formaldehyde, paraformaldehyde, furfuraldehyde and hexamethylenetetramine with the chlorinated products obtained by passing chlorine gas into cashew nut shell liquid chlorinated to twice its original weight is mixed with (a) paraformaldehyde and cured at 275 DEG  F. for 24 hours; (b) furfuraldehyde and cured at 270 DEG  F. for 24 hours.  The rubbery products so formed may be incorporated in rubber compositions suitable for making brake and clutch facings of the moulded and extruded type.  A brake band may be made by mixing any of the products of (a) or (b) above with rubber, sulphur, lithage and zinc oxide, moulded to shape and the brake band cured at 40 lbs. steam pressure until set.  This subject-matter does not appear in the Specification as accepted.ALSO:An insecticidal composition comprises an insecticidal rotenone and/or pyrethrum-bearing material in admixture with the chlorination product of a phenol having an unsaturated hydrocarbon side chain of 14 to 28 carbon atoms or a derivative thereof in a petroleum oil.  5 to 20 per cent of the said chlorination product (based on the weight of the petroleum oil) containing 5 to 20 per cent of the pyrethrin material is preferred.  Specified phenols are those obtained from the Anacardiaceae family of trees such as cashew nut shell liquid, marking nut shell liquid and Japanese lac; their constituents such as anarcardic acid, cardol, anacardol and urushiol; derivatives thereof such as cardanol, the distillate and residue from the steam distillation of cashew nut shell liquid and marking nut shell liquid, hydrocarbon ethers, the polymers and copolymers such as are disclosed in U.S.A.  Specifications 2,067,919, 2,128,247 and 2,176,059.  Such phenols are chlorinated to any desired extent by bubbling free chlorine through the liquid phenol or the phenol dissolved in petroleum oil (see Group IVb).  The Specification as open to inspection under Sect. 91 contains the subject-matter of Specification 643,480.  This subject-matter does not appear in the Specification as accepted.
