Abstract

245,633. Potts, H. E., (Zeche M. Stinnes). March 7, 1925. Tar oils, extracting and purifying.-Lom--temperature tar or tar distillates are separated into phenol and hydrocarbons by mixing with dilute, for example 56 per cent, alcohol, and passing ammonia gas into the mixture until saturated, the heat of absorption being removed by cooling. The liquid separates into two layers, the top containing hydrocarbons and the bottom a solution of phenols. The hydrocarbons are heated to 180‹ C. to remove alcohol and ammonia and may then be distilled. The solution of phenols is distilled at 90‹ to 95‹ C. to remove alcohol, ammonia and some water, and on cooling the phenols separate out and may be further purified by distillation. The recovered ammonia, alcohol and water may be used again.
