Title: Process for the manufacture of organic antimony compounds
IPC: C07F9/92
Filed: 1928-02-01
Abstract: 313,058. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Feb. 1, 1928. Aromatic pentavalent-antimony compounds are prepared in solution by treating a mixture of an aromatic diazonium salt and an antimony halide, or a double compound of a diazonium halide with an antimony halide, with a tertiary base such as pyridine or quinoline. The products may be decomposed with water to form the corresponding stibinic acid. According to the examples, (1) the double compound of benzene diazonium chloride and antimony trichloride is heated in pyridine until the evolution of nitrogen ceases; if the solution of the resulting phenyl antimonic chloride be poured into water, phenylstibinic acid separates out; p-diaxonium acetanilide may replace the benzene diazonium chloride; (2) o-chlor-p-aminoacetanilide is diazotized and treated with antimony oxide dissolved in hydrochloric acid; the resulting double compound is introduced into pyridine, when the spontaneous rise in temperature causes the evolution of nitrogen; on pouring the product into water, m-chlor-p-acetylaminophenylstibinic acid is formed. Instead of starting with the double compound, the components may be individually introduced into the tertiary base, in which case the diazonium halide may be replaced by any diazonium salt.

Patent GB-489781-A (GB)
Title: Improvements in or relating to thread or the like, and particularly artificial silk thread, method of drying same and apparatus therefor
IPC: D01D10/04
Filed: 1937-02-09
Abstract: <PICT:0489781/IV/1> Wet thread, particularly artificial silk, is advanced axially in a plurality of generally helical turns around a reel, the surface contour of which in axial section corresponds substantially to the predetermined free shrinkage curve of the thread.  The reduction in diameter of the reel in the direction of advance of the thread may be somewhat greater than the <PICT:0489781/IV/2> reduction in diameter of the helical turns of thread.  If desired, a reel may be used with one end of such form that the turns of thread advanced thereon are equal, the thread being dried on this portion of the reel before it reaches a stage where the tendency to shrink is pronounced.  In order to obtain a thread with a small but uniform residual shrinkage capacity, a portion of the reel at the discharge end may be constructed so that the turns of thread advanced thereon are equal.  In the case of viscose thread, the residual capacity to shrink may be from 4,5 per cent to less than 1 per cent.  Thread treated by the process presents an uncrinkled appearance when free from tension.  Artificial silk obtained by the viscose, nitrocellulose, or cuprammonium process may be treated. Before the drying step it may, continuously with or separately from the spinning operation, be treated with desulphuring, bleaching, and other liquids.  As shown in Fig. 7, the heavy line A, D shows the contour of a drying reel varying but slightly from the theoretical contour a, d calculated from the shrinkage curve of a particular thread.  From point A to B where the thread contains a high content of moisture, the shrinkage is very small and in practice it is sufficient to make the part AB of the reel cylindrical.  From B to C where the tendency for the thread to shrink is great, the reel tapers, and from C to D where the shrinkage tendency is again very small, the reel is cylindrical.  As shown in Fig. 11, the reel employed is of cantilever form, having one end free.  It is made up of two sets of bars 35, 36 mounted with their axes of rotation offset from and askew to each other.  The general construction and operation of the reel are similar to those described in Specification 474,973. Drying of the thread may be effected by passing heated air through the hollow shaft 34, holes 51, chamber 52, and holes 53, and then between the bars 35, 36, and through the thread coil.  To assist the drying operation, the reel may be arranged within a casing. The contour of the reel corresponds substantially to the free shrinkage curve of the thread to be dried thereon, the parts AB and CD being cylindrical and the part BC being conical.  The reel is preferably made of aluminium or other metal having good heat conductivity. Preferably, the thread is supplied to the drying reel under little or no tension.  The treatment is applicable to the drying of artificial filaments, horsehair, staple fibre, and ribbon.  Specification 413,413 also is referred to.
