Abstract

Compounds obtained by condensing anacardic materials (e.g cashew nut shell liquid) with poly-chloro-hydrocarbons, such compounds containing chlorine, are used in resinous compositions. Phenol-aldehyde compositions.-The chlorine-containing condensation products are used as plasticizers especially for oil-soluble phenolformaldehyde resins, to impart flexibility and improved impact strength, particularly for brake linings. An example is given wherein a fusible resin is prepared from cresylic acid, formaldehyde and ammonia, mixed with one of the condensation products and dissolved in alcohol. This solution may be applied as a coating to paper, wood or metal, before or after heating to render the resin infusible. Resinic acid compositions.-Linseed oil is heated and mixed while hot with ester gum and one of the condensation products. The mix is partially cooled, and driers and thinners added; after cooling to room temperature, aluminium powder is added. If desired, further addition of the condensation product may be made during the cooling. The resulting product may be used as a fungicidal and insecticidal paint. Vinyl &c. polymerization products. The condensation products are solvents for synthetic rubbers and impart thereto high tensile and tear strength. They may be compounded with copolymers of butadiene and styrene, copolymers of butadiene and acrylonitrile and polymers of 2-chlor-butadiene. An example including zinc oxide, carbon black, aldo-alpha-naphthylamine, benzothiazyl disulphide and sulphur is given.ALSO:Anacardic materials such as cashew nut shell liquid (which may have been pre-treated) are heated with a di- or higher-chlorinated hydrocarbon of at least two carbon atoms, having at least one terminal chlorinated aliphatic group and at least one hydrogen atom, whereby chlorine-containing derivatives are obtained, the chlorine-content being from about 10 to 16 per cent. The reaction is preferably carried out in the presence of an alkali, e.g. sodium or potassium hydroxide, in aqueous solution. Preferred proportions are at least one mole of the alkali and one to two moles of chlorine-compound to one mole of anacardic material. Heating is carried out to at least 90 DEG C. at atmospheric or higher pressure. Specified chlorine compounds are trichlorpropane, polychlorpentane, 1 : 2 : 2-trichlorethane, dichlorpentane, trichlorethylene, o-chlor-benzyl chloride, tetrachlorethane, dichlorphenyltrichlorethane and 1 - (o - chlorphenyl) - 2 - chlorethane. Examples are given of the use of some of these compounds, the products showing only a slight change in viscosity on heating with hexamethylene tetramine. The products may in some cases be hydrolysed to convert the chlorine atom(s) into hydroxyl group(s).ALSO:Rubbers, natural and synthetic, are improved by the incorporation of a chlorine-containing condensation product from anacardic materials (e.g. cashew nut shell liquid) and a poly-chlorohydrocarbon. The condensation product is a solvent for the rubber and increases the tensile strength and tear strength. An example is given of a synthetic rubber composition.ALSO:Condensation products from anacardic materials (e.g., cashew nut shell liquid) and poly-chloro hydrocarbons, such products containing chlorine, are used as insecticides either alone or with derris root extract, rotenone, pyrethrum or D.D.T. When used as a spray they may be thinned with a solvent such as kerosene, or emulsified in water with soap, &c., with or without kerosene. A further application is in the field of fungicidal and insecticidal paints, compounded with linseed oil, ester gum, driers, thinners and aluminium powder.
