Abstract
The research the processes of aqueous alkaline extraction of resin from coal and production of phenol at the temperature of 200-250 °C. It is known that for the extraction of phenols from fractions, extraction with polar solvents is used. In this article, butyl acetate was used for the efficient extraction of phenol using an extraction method, and a buffer solution is hydroxide calcium hydroxide Ca(OH)2, pH 12.45 and compared with NaOH solution, pH 12. It has been shown that the extraction of phenol from coal tar resin gives a very good buffer solution Ca(OH)2, pH 12.45 using butyl acetate. It was established that the extraction of phenol from the resin using butyl acetate with a solution of slaked lime gives very good results, the extraction of phenol reaches up to 94-97.5%.
