Abstract
1,161,057. Amidating alcohols. ARMOUR & CO. 3 Oct., 1966 [24 Oct., 1965], No. 44088/66. Heading C2C. Amides of the formulµ and where R<SP>1</SP>, R<SP>2</SP> and R<SP>3</SP>, the same or different, are H, alkyl, arylalkyl, or cycloalkyl containing from 2 to 48 carbon atoms, at least one radical being other than H, R<SP>4</SP>, R<SP>5</SP> and R<SP>6</SP>, the same or different, are H, alkyl, arylalkyl or cycloalkyl, R<SP>7</SP> is H, alkyl, aryl, aminoalkyl or metallic salts of said aminoalkyl, containing from 1 to 21 carbon atoms, and (a + b + c) = 2 to 9, are prepared by reacting the corresponding alcohols with a nitrile of the formula R<SP>7</SP>-C# N, in the presence of a large molar excess of anhydrous liquid hydrogen fluoride. The temperature employed is generally 0 to 130‹ C. and the reaction time is generally within the range of 5 minutes to 2 hours. A stoichiometric excess of nitrile is preferred, and also a mole ratio of hydrogen fluoride to alcohol of greater than 3. The products may be hydrolysed to the corresponding amines using a hydrolysis reagent comprising an acid or base in aqueous or alcohol solution.
