Title: Method of preparing alpha-naphthylacetamide
IPC: C07C233/00
Filed: 1943-04-06
Abstract: Alpha-naphthyl acetamide is prepared by heating a solution of alpha-naphthyl aceto nitrile in sulphuric acid which must contain only a sufficient quantity of water to permit solubility of the alpha-naphthyl acetonitrile therein.  The solution of alpha-naphthyl acetonitrile in sulphuric acid is heated preferably at a temperature between 70 DEG  and 150 DEG  C., cooled and poured into a sufficient quantity of water to precipitate the alpha-naphthyl acetamide which is filtered off, washed with water and dried.  It can be freed of small quantities of alpha-naphthyl acetic acid which may form in the process, by washing with 5 per cent aqueous sodium hydroxide.  In examples: (1) 165 parts of alpha-naphthyl acetonitrile, 258 parts of 96 per cent sulphuric acid and 9 parts of water are heated at 140 DEG C. and the resulting amide isolated as described above; (2) 110 parts of the nitrile in 172 parts of sulphuric acid (96 per cent) are reacted similarly. Alpha-naphthylacetamide is an effective apple-drop preventive; the alpha-naphthylacetic acid is a plant growth promoter.

Title: A method of isolating lactams
IPC: C07D201/16
Filed: 1949-03-01
Abstract: Lactams, made by Beckmann's rearrangement of cyclic ketoximes, are purified by recrystallization by cooling a hot saturated solution thereof in aliphatic volatile hydrocarbons, e.g. benzine, gasolene or petrol ether, by boiling under reduced pressure in a container fitted with an efficient reflux cooler. Better results are obtained if a small quantity of another organic solvent which does not mix with the main solvent, especially chloroform, is added.  2-3 per cent of chloroform may be used. The method avoids metallic contamination of the product by the use of metal stirrers and gives a whiter product yielding stronger polyamide fibres than that obtained by purification by vacuum distillation.  In an example, raw 6-caprolactan is recrystallized from light benzine.
