Title: Process for the manufacture of hydrides and/or halogen-containing hydrides of boron and silicon
IPC: C01B35/02
Filed: 1960-07-05
Abstract: 904,113. Electrolytic production of boron or silicon hydrides. WACKER-CHEMIE G.m.b.H. July 5, 1960 [July 7, 1959], No. 23501/60. Class 41. Hydrides and/or halogencontaining hydrides of boron or silicon are manufactured by electrolysing a melt of one or more alkali metal halides using electrodes made of boron or silicon, or a boron or silicon anode with the cathode of another conducting substance, such as iron, titanium, tantalum, nickel, steel alloys or silicon carbide, whilst hydrogen is introduced into the melt on the anode and/or cathode side. The melt may also contain one or more halides of Group 2A or 3A metals, e.g. Be, Mg, Ca, Sr, Ba, A1, Sc, Y, or lanthanides. Preferably, the melt consists of LiCl, KC1 and NaCl and has a melting-point not greater than 400‹ C. The boron or silicon electrode(s) may consist of particulate boron or silicon, with the current supplied by a graphite or carbon body, or of sintered or cast boron or silicon rods. Fig. 1 shows apparatus for producing a gas containing, e.g. SiHCl 3 , SiH 2 Cl 2 , SiH 3 Cl or SiH 4  by using pieces of silicon 3 filling a cupshaped silicated graphite anode 2. The cathode is an iron tube 4 with fitted at the bottom a porous distributer plate 5 of sintered titanium or iron wire netting for distributing hydrogen into the melt; a funnel-shaped insert 8 prevents convection. The whole may be enclosed under atmospheric or superatmospheric pressure in a vertical quartz tube 1 surrounded by a radiant heating device 6. The silicon consumed at the anode is continuously replaced. Boranes, e.g. B 2 H 9 , and traces of chlorinated boranes may be similarly produced using particulate boron with a trace of NaF added to the melt. To prevent the formation of halogen-silanes or halogenboranes, a secondary graphite or carbon anode 7 may be used at the outset of electrolysis prior to working the anode 2.

[Also in Division B5] A filter element for separating solids from liquids, or gases, comprises filter-cloth 12, Fig. 4b, made of e.g. metal or plastic threads, which is reinforced on one, or both, of its faces by metal-wire mesh 11 having a coating of plastics material, the element being made preferably by heating the mesh, coating it with the material and applying it to the cloth before it is cooled, whereby the cloth and the mesh are bonded to one another. A plurality of such filter elements, each having a supporting frame 13, Fig. 4, may be linked to form a rotatable band-like screen 1, Fig. 1, through which water to be filtered flows inwardly, solid material collected by the screen being washed therefrom by a water-spray 2 and collected in a box 3. Alternatively, the filter elements may be arranged to form a rotatable drum, Fig. 2 (not shown), through which water to be filtered flows outwardly, solid material being washed from the screen by a water-spray into a box lodged within the drum. A single filter-element may form a stationary or rotatable screen 10, Fig. 3, of circular configuration from which solid material is washed by a stream of water Z and deposited in a stationary or rotatable box 4 at the end of a suction-pipe 5. Fluid to be filtered flows upwardly through the screen and if the screen is stationary the box 4 is rotated by a driving shaft through bevel gearing, the box being fixed if the screen is rotatable.

The capillary tube 2 may be made of electrically conductive material and serve as the electrode. As shown in Fig. 1, the liquid 3 in the container 1 is prevented from escaping by the capillary action of the tube 2. When the switch 5 is closed, Fig. 2, electrical charges of like polarity are set up on the surface of the liquid at the orifice so that the electrical charges cause a repelling action and cause the drips to be formed and separated in regular succession. An earthed ring 4 promotes the separation and accelerates the dripping into a collecting vessel (6). The duration of the closing of the switch is proportional to the quantity dispensed. In Fig. 3 (not shown) the collecting vessel (6) is earthed and the ring 4 is replaced by a ring-shaped electrical grid (9) which is supplied with a voltage lower than that to the electrode. In Fig. 4 (not shown) the diameter of the capillary tube is increased and a cylindrical pin extends into the tube to provide the capillary; if desired, the pin may serve as the electrode.

Title: Process for the production of terephthalic acid
IPC: C07C63/26
Filed: 1955-08-24
Abstract: Terephthalic acid is made by subjecting tri-p-toluyl triazine to the action of an aqueous oxidizing agent capable of hydrolysing the triazine nucleus.  Oxidizing agents specified are aqueous nitric acid, aqueous mixtures of nitric acid with other mineral acids, and oxides of nitrogen such as nitrous anhydride or nitrogen dioxide and water.  The reaction may be effected in the liquid phase at temperatures of 150-250 DEG  C. under pressure. Oxygen or oxygen-containing gases may be introduced into the reaction chamber simultaneously with the nitric acid or nitrous gases, or nitric oxide may be continuously withdrawn from the reaction, oxidized with oxygen or air to form higher oxides of nitrogen or nitric acid and recycled. In examples, tri-p-toluyl triazine is reacted at elevated temperatures and pressures with (1) aqueous nitric acid, and (2) an aqueous mixture of nitric and sulphuric acids, to form terephthalic acid.  Specification 731,135 is referred to.
