Abstract
285,797. Zaidan Hojin Rikagaku Kenkyujo. Feb. 18, 1927, [Convention date]. Insecticides are prepared by mixing an extract of derris root with an anhydrous and alkali-free vehicle consisting of one or more oils, fats, waxes, resins, higher alcohols, higher hydrocarbons, or higher fatty acids, together with an anhydrous solvent such as benzol, carbon tetrachloride, or trichlor-ethane. The primary material so prepared is mixed, when required for use, with an aqueous soap solution so as to form an emulsion or colloidal solution. According to examples derris root is extracted with ether or benzol, the solvent recovered from the extract by evaporation. and the active substance so obtained is dissolved in mixture of fish oil and benzol or carbon tetrachloride so as to form the primary material as a liquid, to which anhydrous gum arabic may be added if a material in the form of powder is required. Specifications 239,483 and 280,256 are referred to.
