Dependence of the Toxic and Protective Properties of Shale Oils on their Content of Water-Soluble Phenols. A large propertion of water-soluble phenols, which are valuable intermediates for synthesis of various high polymers, is now extracted from shale oil, which is largely used for impregnation of wood. Changes in the technology of production of shale impregnaing oil make it necessary to examine the rationality of removing water-soluble phenols from shale distillate oil in relation to changes in its physicochemical characteristics, toxicity, and protective action. Four samples of shale oil, physicochemical properties included, were investigated. The toxicity of the four oil samples and of water-soluble phenols was estimated by determination of the threshold absorption A/sub 95/ in accordance with State All-Union Standard specifications on a culture of one of the most active wood-destroying fungi, Coniophor cerebella. Pine sapwood spcimens were used. It was concluded that there is no definite correlation between the toxicity, which is the main indicator of the suitability of a given antiseptic for protecting wood against wood-destroying fungi, and the presence of water-soluble phenols in the shale oil. Experimental data showed no significant differences in destruction of wood impregnated with the shale oil and subjected to heat treatment. Experimental data was also included for the influence of washing out of shale oils from impregnated wood with water on destruction of the wood. All the protective properties of impregnating oils are a complex function of their composition and of the structure of their compounds. 3 tables. (DP)
