Patent GB-740891-A (GB)
Title: Improvements in the production of amides
Inventor: LINCOLN JAMES
IPC: C07D201/04
Filed: 1952-05-15
Abstract: Amides are produced by a process which comprises effecting the Beckmann transformation of the corresponding oxime by means of sulphuric acid partly neutralized with ammonia, i.e. a composition such as can be obtained by reacting sulphuric acid with ammonia in amount less than is required to convert all the sulphuric acid present into ammonium sulphate.  Ammonium bisulphate may be employed with or without some sulphuric acid as catalyst.  A cyclic process may be carried out by neutralizing the reaction mixture with ammonia, separating the resulting ammonium sulphate, decomposing the ammonium sulphate to ammonium bisulphate and the ammonia with further oxime. When ammonium bisulphate is employed the melting-point thereof may be reduced by the addition of water, monoammonium dihydrogen phosphate or other salt or flux or sulphuric acid.  Alternatively the reaction may be carried out in a medium which is liquid at ordinary temperatures, e.g. acetic acid.  Small amounts of water may be eliminated by the addition of acetic anhydride.  Other solvents may be used, e.g. monochlor-, dichlor- or trichloracetic acid and a mixture of chlorinated acetic acid and acetic acid may be employed such that the boiling point of the mixture is the desired reaction temperature.  The reaction product, e.g. caprolactam, may be used instead of or in addition to acetic acid or a mixture of acetic acid and a chlorinated acetic acid, especially in a cyclic process.  In examples: cyclohexanone oxime is gradually added to a mixture of ammonium bisulphate, ammonium dihydrogen phosphate and acetic acid under reflux, ammonia is added to the cooled reacted mixture to convert ammonium bisulphate to the sulphate which is filtered off, the crude lactam liquor is extracted and worked up, the ammonium sulphate is heated to form ammonia which is collected in water for further neutralization and ammonium bisulphate which is used in the transformation of further oxime (1); in a similar process cyclohexanone oxime is added to a mixture of ammonium bisulphate, sulphuric acid, monoammonium dihydrogen phosphate and glacial acetic acid (2); and in similar processes cyclohexanone oxime is added to a mixture of ammonium bisulphate, glacial acetic acid and monochloracetic acid (3 and 4).  Suberone oxime may be converted to the corresponding lactam and oximes of benzophenone and diethyl ketone may be converted to benzanilide and propionethylamide respectively.

Title: Process for improving vegetable textile material
IPC: D06M15/05
Filed: 1924-05-22
Abstract: Textile materials of vegetable origin are treated with a halohydrin, in particular the halohydrin of a polyalcohol, in the presence of alkali, in order to impart to them a silky gloss or an elastic finish.  Suitable halohydrins are a -monochlorhydrin, epichlorhydrin and ethylene chlorhydrin; and the preferred alkali is caustic soda, although others such as alkali sulphides may be employed.  The treatments with halohydrin and alkali may take place simultaneously or in either sequence; and the materials to be treated may be either in the crude state or they may be subjected to a preliminary treatment such as boiling with dilute alkali, bleaching or mercerizing, or they may have been prepared by treatment with an hydrolyzing- or gelatinizing-agent such as strong mineral acid, ammoniacal copper oxide solution or thiocyanate solution.  If the material is first treated with alkali, a caustic soda solution of 10-50 per cent strength, preferably 12-40 per cent strength, is suitable, and the quantity used may be 2-10 times the weight of the material, but usually 2-4 times the weight of the latter will be sufficient: the preliminary treatment with caustic soda may be conducted at 10-50 DEG  C, although if the lye is not too weak, room temperature is adequate: the lye used may contain some alcohol; the halohydrin is applied immediately after the caustic alkali treatment, or p  after standing, and it may be brought into contact with the material as a solution or in suspension, a thickening- or binding-agent being, if desired, added; it is sufficient to employ not more than two molecular proportions of halohydrin for each molecular proportion of caustic alkali, although in most cases 0.3-0.75 molecular proportions are sufficient.  The material, after treatment, is washed optionally after drying; or it may be advantageously treated with an inorganic or organic acid, or an acid salt, or an ammonium or other salt, or with tannin or formaldehyde solution; or with any other precipitant for viscose or ammoniacal-copper-oxide cellulose.
