The distillation of coal for the production of gas, coke and the tarry materials used for the manufacture of dyes and organic chemicals results in a watery waste known as ammoniacal gas liquor, and the disposal of this is a cause of pollution. Ammoniacal gas liquor contains free ammonia, ammonium salts, cyanide, sulphide, thiocyanate, and a variety of aromatic compounds including pyridine, phenols, cresols and xylenols. ... Gas liquor, discharged untreated to a stream, has an extremely high oxygen demand, many times greater than that of sewage.  1, fiche 1, Anglais, - ammoniacal%20gas%20liquor
