Title: Process and apparatus for the electrolytic extraction of titanium metal
IPC: C25C7/00
Filed: 1955-10-28
Abstract: 786,460. Electrodeposition of molten titanium. NORTON GRINDING WHEEL CO., Ltd. Oct. 28, 1955 [Nov. 10, 1954], No. 30865/55. Class 41. Molten titanium is cathodically deposited in an inert atmosphere in a D.C. cell containing apart from any titanium halide a fused halide or mixture of fused halides having a melting point below and a boiling point of at least 1660‹ C., said halides being selected from the chlorides of sodium, potassium, magnesium, calcium, and barium and the alkali and alkaline earth metal fluorides other than those of caesium and radium but including that of magnesium, the cell being of copper, silver copper or silver base alloys, or mixtures thereof, and the anode being of titanium carbide which may contain minor proportions of titanium nitride, the oxides Ti 2 O 3 , TiO, Ti 3 O 2 , Ti 2 O, or mixtures thereof. As shown, the cell comprises a cylindrical copper shell 45 having hollow walls through which water is continuously circulated along pipes 48, 49 and supported by a flanged recessed ring 40 of insulating material such as asbestos board acting as a sealing gasket between upper and lower casings 25, 31, the upper casing having insulated bushes carrying the pipes. A titanium ingot 54 clamped by a ring 61 to a screw jack closes the bottom of the cell and serves as cathode while the anode 10 is screw-threaded into a carbon or graphite rod 11 making a sliding fit in a bush 14 of insulating refractory material, such as alumina, zirconia or boron carbide. Initially the anode is placed in contact with the ingot, the cell filled with granular salts an argon stream is passed from pipe 96 to pipe 97, and an arc is struck, e.g. at 20 volts. The salt and the end of the ingot melt as may be seen through a sight tube 93 and the controlling circuit is then changed to apply an electrolysing voltage of say, 5 volts. The operating temperature is maintained constant by an automatic control system which raises or lowers the anode to adjust the cell current. An automatic device for withdrawing the anode to make the initial arc may also be provided. The growing ingot of titanium is withdrawn by the jack when the temperature of the ingot is judged to be 1300‹ C. as seen through the peep-hole 80. Additions of salt may be effected through the sight tube 93 and the anodes may be changed rapidly by mechanical handling gear. Since only low voltages are used, the insulating gasket 30 and the insulating bushes for the pipes 48, 49 may be omitted. A modification is mentioned in which the cell is operated under pressure due to the use of salt electrolytes boiling at or near the melting point of titanium. Specification 744,396 is referred to.

Title: Esterification process
IPC: C07C67/00
Filed: 1950-12-27
Abstract: Cellulose esters are obtained by reacting cellulose or a cellulose derivative with an acid in the presence of a carbodiimide which becomes converted to a urea derivative.  In an example acetyl-cellulose is reacted with monochloroacetic acid in the presence of dicyclo-hexyl-carbodiimide and a small quantity of pyridine to give cellulose-aceto-chloracetate and dicyclohexyl-urea. Specification 685,970, [Group IV (b), is referred to.ALSO:Carboxylic acid esters are obtained by reacting an organic carboxylic acid with an alcohol in the presence of a carbodiimide. p  The reaction proceeds as follows:-R1COOH + R2.OH + R3N = C = N.R4--> R1COOR2 + R3NH.CO.NHR4 where R3 and R4 are hydrogen, a straight or branched saturated or unsaturated aliphatic chain which may carry any substituents or are hydroaromatic radicals which may be substituted; R1 is H, an aliphatic or aromatic radical and R2 is any aliphatic radical.  The reaction proceeds at room temperature or slightly above and may be carried out in the presence of a solvent dissolving one or more of the reactants.  In some cases it is preferable to operate in a two-phase system and it may be desirable to add a small amount of pyridine to the reaction mixture.  In the examples: (a) salicylic acid is reacted with methanol in the presence of methyl-tertiary-butyl-carbodiimide to give salicylic acid methyl ester; (b) phenoxy acetic acid is reacted with methyl alcohol in the presence of methyl-tertiary-butyl carbodiimide to give phenoxy-acetic acid methyl ester; (c) b -chloroethyl alcohol is reacted with chloroacetic acid in the presence of di-isopropylcarbodiimide to give the b -chloro-ethyl-ester of chloroacetic acid and diisopropyl urea; (d) b -chloro-ethyl alcohol is reacted with chloroacetic acid in the presence of dicyclohexyl carbodiimide to give the b -chloro-ethyl-ester of chloroacetic acid and dicyclohexyl-urea; (e) a fatty acid mixture prepared from rape oil is treated with methanol in the presence of methyl-tertiary-butyl-carbodiimide to give the methyl esters of the acids; (f) acetyl cellulose is reacted with nonochloroacetic acid in the presence of dicyclohexyl-carbodiimide to give cellulose-aceto-chloroacetate and dicyclohexyl urea. Specification 685,970 is referred to.
