a coaltar fraction, boiling between 240° and 270°C. The crude creosote oil is used as raw material for producing tar acids etc, or used direct as germicide, insecticide, or disinfectant in various connections (eg soaps, sheep dips, impregnation of railway sleepers etc)., a distillate obtained from tars, nowadays almost entirely from coal tar, by high-temperature carbonisation of bituminous coal and consisting mainly of liquid and solid aromatic hydrocarbons with appreciable quantities of tar acids and tar bases; it is heavier than water and has a continuous boiling range of at least 125 degrees C, beginning at ca. 200 degrees C
