    摘要: The present invention provides a method for preparing solid p-disodium hydroxybenzoate which is characterized by comprising the steps of reacting phenol, carbon tetrachloride in an amount of 0.9 to 1.2 moles per mole of phenol and sodium hydroxide in an amount of 7 to 20 moles per mole of phenol prior to the reaction in an aqueous liquid containing 10 to 40% by weight of p-disodium hydroxybenzoate and/or sodium chloride in the presence of a transition metal powder in an amount of 0.01 to 1.00% by weight based on the weight of a reaction system at a reaction temperature of 50.degree. to 150.degree. C.; cooling the resulting reaction mixture to a level of -20.degree. to +20.degree. C.; and separating said p-disodium hydroxybenzoate therefrom.

    摘要: An acylnorbornanone acetal is represented by the formula: ##STR1## (wherein R.sub.1 is a saturated hydrocarbon group having 2 to 7 carbon atoms and R.sub.2 is a hydrogen atom or a hydrocabon group having 1 to 10 carbon atoms). The acylnorbornanone acetal is prepared by oxidizing an .alpha.-hydroxyalkylnorbornanone acetal represented by the formula: ##STR2## (wherein R.sub.2 is a hydrogen atom or a hydrocarbon group having 2 to 7 carbon atoms). The perfume composition contains as a perfume component the acylnorbornanone acetal as represented above.

    摘要: A safe and reliable method of decomposing halogenated aromatic compounds, wherein a heat-resistant alkaline polar solvent containing halogenated aromatic compounds is contacted with a alkali at a temperature ranging from about 100.degree. C. to 300.degree. C. in order to decompose the halogenated aromatic compounds. The used solvent is removed of solid contents of salts, alkalis and the like, whereby it can be recycled.
