Title: Improvements in or relating to the production of aralkyl carboxylic acid amides
Filed: 1953-12-29
Abstract: Aralkyl carboxylic acid amides are prepared by passing an aryl alkyl ketone, water and ammonia in continuous manner under such conditions of temperature and pressure that all are at least partly in the liquid phase, over a porous adsorbent solid, and while elemental sulphur is present in admixture with the liquid phase and/or in admixture with the porous adsorbent solid.  The amides may be hydrolysed to the corresponding acids.  Specified porous adsorbent solids are pumice, silica gel, activated charcoal, diatomaceous earth and natural clay.  In a modification of the process, an alkyl aryl ketone, water and ammonium polysulphide are passed over a porous adsorbent solid under the conditions specified above.  Liquid sulphur may be passed over the porous support either concurrent with or in counter-current to the other reactants, in order to replace any sulphur removed in the reaction products.  Mutual solvents for the ketone, water and ammonia or ammonium polysulphide may be used and ethanol, dioxan and pyridine are specified.  Hydrogen sulphide is periodically purged from the system.  The reaction products may be distilled to remove water, ammonia and solvent, the amide crystallized and removed from the residue and any neutral byproducts or unreacted ketone recycled, preferably after distillation, to the reaction zone.  Alternatively, the reaction product may be cooled to crystallize the amide which is removed by filtration, part of the filtrate being recycled, the remainder being a purge stream which is distilled, only the overhead product being recycled.  Specified reaction conditions are temperatures of 120-250 DEG  C., pressures of 100-1000 pounds per square inch and feed rates of 0.1 to 5 volumes of reactants per volume of solid packing per hour. Starting materials are ketones of formul  R1-CO-R2 or R2-CO-R4-CO-R3 wherein R1 is a monovalent aryl group, R2 and R3 are alkyl groups of up to five carbon atoms and R4 is a divalent aryl group, such as acetophenone, methyl or dimethyl acetophenones, diacetyl benzenes and methyl naphthyl ketones.  In an Example, a mixture of acetophenone, ethanol and aqueous ammonia was passed at elevated temperature and pressure over pumice carrying elemental sulphur, the liquid reaction product was cooled and the phenylacetamide which crystallized removed, the filtrate distilled to remove ethanol, ammonia and some ammonium sulphide, the rest of the phenylacetamide being obtained by ether extraction of the residue. Further extraction of the residue with aqueous sodium hydroxide yielded a small amount of phenylacetic acid. The phenylacetamide was hydrolysed to phenylacetic acid by boiling with aqueous sodium hydroxide solution followed by acidification with hydrochloric acid.
