    Abstract: Saturated hydroxy carboxylic acid nitriles and/or unsaturated carboxylic acid nitriles are prepared by reacting a lactone or a C-alkylated lactone with gaseous ammonia in the presence of an acid dehydration catalyst at elevated temperature. The omega-hydroxy carboxylic acid amide may be obtained as by-products. Specified lactones are gamma-butyro-, deltavalero-, epsilon-capro-, zeta-oenantho-, etacaprylo-lactones and their alkyl derivatives. Suitable dehydration catalysts include phosphoric acid, acid phosphates, boron phosphates and sulphuric acid and its acid salts, as such or on carriers.
