Abstract: Silicon tetrafluoride is removed from gaseous boron trifluoride by treating the gas in a first stage at temperatures of from 10 to 60@C with a solution containing from 55 to 70% by weight of dissolved boron trifluoride. From this stage there is drawn off an exit gas which comprises practically pure silicon tetrafluoride and also a boron trifluoride-enriched solution from which boron trifluoride is desorbed at temperatures of from 90 to 200@C.

Abstract: A process for producing phosphorus-containing iron powder involves heating a mixture of finely divided carbonyl iron and elemental phosphorus and pulverising the product. Preferably, a mixture of 70-99 wt.% finely divided carbonyl iron powder and 1-30 wt.% red phosphorus is heated at above 300 degrees C in an inert gas atmosphere. Also claimed is a phosphorus-containing iron powder of less than 10 mu mean particle diameter, containing 0.1-80 wt.% P, less than 1 wt.% C, less than 1 wt.% N, less than 0.5 wt.% H and less than 0.1 wt.% total of other impurity elements except oxygen.

Abstract: Preparation of carbonyl diisocyanate (I) from trichloroisocyanuric acid (II) comprises heating (II) in a reactor at 225-500 deg C, optionally in the presence of carbon monoxide (CO) and/or whilst irradiating with ultraviolet (UV) light, for a time such that no nitrogen trichloride (NCl3) is present in the discharge from the reactor.

Abstract: To produce alkali metal nitrates, alkali metal chloride solution is fed to the anode space (2) of an electrolysis cell (3), the anode space (2) being separated from the cathode space (5) by a permselective cation exchanger membrane (6). Simultaneously fed to the cathode space (5) is a nitric acid/alkali metal nitrate solution whose alkali metal nitrate concentration is not less than 10% by weight and whose HNO3 concentration is between 0.1 and 10% by weight. A solution whose pH does not exceed 5 is removed from the cathode space (5). … …
