Title: Method of producing alkali metal borates of lowered iron content
IPC: C01B35/12
Filed: 1962-04-03
Abstract: Alkali metal borates are purified and freed from iron by electrolysis of an aqueous borate solution in the presence of a soluble S-compound excluding sulphates, e.g. thiosulphates, sulphides, or polythionates. The voltage applied exceeds the deposition voltage of iron, whereby iron and iron sulphide are deposited at the cathode.  In examples, sodium meta- or dicaborate solution, preferably freed from solid suspensions, and containing a small amount of a soluble sulphide, thiosulphate, or polythionate, which may already be present in the crude product, is passed through an electiolytic cell operated at 2 to 6 volts for up to 28 mins. residence time.  The electrolyte which contains less than 10 parts per million of iron is then crystallized.

Title: Improved process for obtaining pure polymerization products of 11-amino undecanoic acid and polymer products so produced
IPC: C08G69/46
Filed: 1954-05-06
Abstract: Impure 11-amino-undecanoic acid (obtained via undecylenic acid and bromo-undecanoic acid from castor oil) in the form of an aqueous paste is heated at temperatures of at least 180 DEG C. to form a partial condensation product insoluble in water, and the separated water is removed in the liquid state from the partial condensation product, carrying with it most of the impurities. The partial condensation product may be washed with water and extracted with benzene, benzine, cyclohexane or methanol to remove remaining impurities, and is subsequently polymerized to the required degree. As an additional purifying step inorganic alkalies, acids or salts which form insoluble compounds with impurities may be added to the amino-acid-water paste or solution and the insoluble compounds separated by filtration after taking up the amino-acid which is then recrystallized.  Active carbon may also be employed in this step. Alternatively the insoluble compounds may be removed by filtering the molten partial condensation product after removal of the water. Acids, alkalies or salts may also be added during the partial condensation. Separation of the water and precondensate may be assisted by adding sand or gravel which increases the specific gravity of the condensate.  Two examples are given in the second of which the additional purifying step referred to is employed.  The properties of polymers from impure and purified materials are compared.
