    摘要： The invention concerns a method for separating a hydroxybenzonitrile-type compound obtained by an amination/dehydration process. More particularly, the invention concerns 2-hydroxybenzonitrile, also called 2-cyanophenol. The inventive method for separating a hydroxybenzonitrile compound from a reaction gas flow comprising it wholly or partly in the form of an ammonium salt is characterized in that it consists in displacing the ammonium ions, through a physical treatment carried out on the reaction gas flow derived from its preparation or from the solid previously recuperated from said flow or according to a chemical treatment carried out on the reaction gas flow, after liquefaction.
