Abstract
1457062 Hydration of nitriles to amides BASF AG 18 April 1974 [19 April 1973] 16922/74 Heading C2C [Also in Division B1] Amides are produced by the addition of water to nitriles in the presence of a catalyst containing copper and magnesium silicate and formed by precipitation of magnesium in the presence of a copper compound using alkali metal silicate and then treating with a reducing gas at elevated temperature. The nitrile may be of the formula R(CN) x where x is 1 or 2 and R is substituted or unsubstituted C 1 to C 6 alkyl- (ene), C 2 to C 6 alkenyl(ene), C 5 or C 6 cycloalkyl- (ene), C 7 to C 12 aralkyl(ene), phenyl(ene) or naphthyl(ene) wherein the suffix «ene» refers to the case when x is 2. The hydration may be carried out with a ratio of 1 to 50 moles water per mole of nitrile group of the feed, a temperature of 50-150‹ C., and atmospheric or superatmospheric pressure. Specified nitrile feeds are: acetonitrile, propionitrile, cyclohexanonitrile, adiponitrile, acrylonitrile, methacrylonitrile, crotononitrile, beta-phenylacrylonitrile, benzonitrile, p-toluonitrile, alpha-naphthonitrile, phthalodinitrile, terephthalodinitrile, isophthalodinitrile, butyronitrile, maleodinitrile, glutarodinitrile, succinodinitrile, valeronitrile, capronitrile, fumarodinitrile, beta-phenylacetonitrile and p-ethoxybenzonitrile. The examples describe hydration of acrylonitrile to acrylamide, methacrylonitrile to methacrylamide, benzonitrile to benzamide, adiponitrile to adipodiamide and acetonitrile to acetamide.
