Title: A process for the production of stabilised acrylonitrile polymer solutions
IPC: C08K5/17
Filed: 1962-07-04
Abstract: Solutions of acrylonitrile polymers in organic solvents may be stabilized against yellow discoloration by the addition of one of the following stabilizers:-(1) A fluosemicarbazide of the general formulae <FORM:0960520/C3/1> in which R and R1 are an alkyl, aryl or aralkyl radical or hydrogen atom and R2 is a hydrogen atom an acyl radical <FORM:0960520/C3/2> radical or <FORM:0960520/C3/3> -NH-C6H5 radical but not more than two of the radicals are R, R1 and R2 are hydrogen atoms;.  (II) A sulphonyl thiosemi carbazide of the general formulae <FORM:0960520/C3/4> in which R1 is an aryl radical, a substituted aryl radical or an alkyl radical and R2 is a hydrogen atom or an alkyl-, aryl or heterocyclic radical.  (III) The combination of (I) above and a compound of the general formulae R3-CO-O-CO-R4 in which R3 and R4 each are alkyl, aryl or araalkyl radicals or are an alkylene bridge or a ring system with 2 free valencies;  (IV) The combination of (a) an acyl thiosemicarbazide of the general formulae <FORM:0960520/C3/5> in which X is a >C=O or >SO2 group, R1 is a hydrogen atom or an alkyl-aryl aralkyl or heterocyclic radical and (b) an acid anhydride and/or (c) a complex forming compound.  (V) A thiosemicarbazide of the general formulae <FORM:0960520/C3/6> in which R1 is an alkyl-, aryl or aralkyl radical or a hydrogen atom and R3 is a alkyl-aralkyl or aryl radical, or mixtures of the above thiosemicabazides with carboxylic acid anhydrides and/or complex forming compounds.  The stabilizers are generally employed in amounts between 0.1-5% by weight.  In the cases where the stabilizer is used in conjunction with a carboxylic acid anhydride and/or a complex forming agent the quantity of carboxylic acid anhydride is 50-5% by weight of the stabilizers and the quantity of complex-forming compound is 50-5% by weight of the quantity of carboxylic acid anhydride used.  The "complex-forming compounds" are compounded capable of reacting with polyvalent metals to produce complex compounds, e.g. salicylic acid 8-hydroxyquinoline or compounds of the ethylene diamine tetra-acetic acid type are preferred. Examples of carboxylic acid anhydrides are acetic acid anhydride, propionic acid anhydride, maleic acid anhydride, succinic acid anhydride, phthalic acid anhydride, benzoic acid anhydride, music acid anhydride and mixed acid anhydrides.  The acrylonitrile polymers may be either acrylonitrite homopolymers or acrylonitrile co-polymers.  A long list of co-monomers is supplied.  It is preferred to use acrylic acid polymers containing at least 80% of formed polyacrylonitrile.  Highly polar solvents such as dimethyl formamide, dimethyl acetamide or ethylene glycol carbonate are used. The production of the polymer solutions is carried out at 10-100 DEG C.  The stabilizer may be added to the solvent or to the polymer solution or together with the polymer into the solvent.

Patent GB-629440-A (GB)
Title: A process for the manufacture of 2-amino-6-hydroxy-8-(hydroxymethyl)-pteridine
Filed: 1947-09-23
Abstract: 2 - Amino - 6 - hydroxy - 8 - (hydroxymethyl)-pteridine is prepared by heating dihydroxyacetone with 2,4,5 - triamino - 6 - hydroxypyrimidine in aqueous solution adjusted to pH 4.5 to 5.5, in the presence of hydrazine.  The dihydroxy-acetone is oxidised by the hydrazine to 3-hydroxy-propanone-2-al-1 which condenses with the pyrimidine to yield the required product which is an intermediate in the production of folic acid.  The presence of boric acid accelerates the reaction.  In examples the required pteridine is obtained by (1) dissolving 2,4,5 - triamino - 6 - hydroxy - pyrimidine sulphate in aqueous sodium acetate-acetic acid solution, heating to 90 DEG  C. and adding simultaneously in an inert atmosphere and at the same rate separate aqueous solutions of dihydroxy-acetone and hydrazine hydrate and (2) heating at 85 DEG  C. in an inert atmosphere an aqueous solution of dihydroxy-acetone, acetic acid, boric acid, 2,4,5-triamino-6-hydroxy-pyrimidine sulphate, sodium acetate and hydrazine hydrate.

Filed: 1944-12-28
Abstract: 590,573. Cooling systems for engines. BAY, T. J. Dec. 28, 1944, No. 26013. [Class 64 (iii)] A cooling system to maintain a constant operating temperature for an internal combustion engine 10, comprises two heat exchangers 11 and 12 of which the former is bye-passed by the pipe 26. - In the example specified in which the engine is. in a ship, sea water passes through the heat exchange element 13 in the cooler 11 to cool the engine jacket water in the element 17, and this water itself cools the oil passing through the element 23 in the exchanger 12. The temperature of the jacket water leaving the engine 10 is maintained constant by the temperature control valve 19 which is actuated by the control element 27 to allow water to byepass the heat exchanger 11, and hence the temperature of the oil is likewise kept at a steady value. On starting the engine, the jacket water byepasses the heat exchanger 11 to heat the oil more quickly, and an orifice 34, which is of fixed dimensions, allows hot jacket water to byepass both heat exchangers, so that the oil may be cooled to a temperature below that of the jacket water entering the engine.

Patent GB-362501-A (GB)
Title: Improvements in or relating to the manufacture of readily soluble non-dyeing thio derivatives of phenols
Filed: 1930-09-05
Abstract: Sulphurized phenol derivatives.--Readily soluble non-dyeing thio derivatives of phenols are made by heating phenol or a homologue or substitution product thereof (other than a phenol containing nitrogen) with an alkali carbonate and sulphur in the presence of water, the proportion of alkali carbonate being sufficient to produce a water-soluble product.  In a modification of the process, the phenol is first caused to react with the alkali carbonate, and the product is heated with sulphur in the presence of water. Advantageously more phenol is used than is necessary for the reaction, the excess phenol being distilled off when the reaction is complete.  The preparation of products from phenol, p-cresol and o-chlorphenol is described in examples.  The products are specially suitable as mordants for basic dyes, cotton mordanted therewith remaining perfectly white.  Specifications 173,313, 298,280, [both in Class 2 (iii), Dyes &c.], and 340,007 are referred to.
