摘要： The present invention relates to a process for separating hydrogen chloride from a mixture comprising an N-(C1-C18)-alkyl-2-pyrrolidone and hydrogen chloride by distilling the mixture comprising an N-(C1-C18)-alkyl-2-pyrrolidone and hydrogen chloride at from 100 to 220null C. and from 50 to 850 hPa in the presence of water by means of a distillation column, condensing the water as water-hydrogen chloride azeotrope at the top by cooling, returning the water-hydrogen chloride azeotrope to the distillation column, separating off gaseous hydrogen chloride at the top and taking off the N-(C1-C18)-alkyl-2-pyrrolidone from the bottom.

摘要： Highly purified ammonia for use in processes for the production of high-precision electronic components is prepared on-site by drawing ammonia vapor from a liquid ammonia reservoir, passing the vapor through a filter capable of filtering out particles of less than 0.005 micron in size, and scrubbing the filtered vapor in a high-pH aqueous scrubber.

摘要： The disclosure relates to removing impurities from hexafluoroethane (CF.sub.3 CF.sub.3), also known as Perfluorocarbon 116 (PFC-116) or Fluorocarbon 116 (FC-116), by using azeotropic distillation such that an overhead product consisting essentially of HCl-hexafluoroethane is formed, optionally combined with a phase separation step to break the HCl-hexafluoroethane azeotropic or azeotrope-like composition thereby permitting recovery of substantially pure hexafluoroethane. Unreacted hydrogen fluoride (HF) may be removed from hexafluoroethane during the above azeotropic distillation with HCl or alternatively by an azeotropic distillation wherein an HF-hexafluoroethane azeotropic or azeotrope-like composition exits overhead and substantially pure HF exits in the bottoms stream.

摘要： A method and an apparatus for cleaning a gas containing pollutants, such as hydrogen chloride and heavy metals, are described. The polluted gas (2) is contacted with an aqueous washing liquid (3) in a scrubber (1), whereupon part of the washing liquid is preevaporated in a preevaporation unit (7) to form a hydrochloric-acid-containing top fraction, which is essentially free from heavy metals, and a bottom fraction containing hydrochloric acid and heavy metals. Part of the bottom fraction is recirculated (15) for renewed preevaporation, while the remainder of the bottom fraction is treated (16) to remove any heavy metals present. The top fraction from the preevaporation is distilled in a rectification unit (22) to form a top fraction (31) and a bottom fraction (35).

摘要： The invention relates to a process for purifyng crude gaseous hydrogen chloride originating from plants producing silane or siloxane and containing as impurities silanes which contain chlorine and/or organic radicals, water, alkanols, hydrocarbons, chlorinated hydrocarbons, organic acids and derivatives thereof, by condensation, compression and fractional distillation. In this process, the crude gas is at least partially freed from condensable products by cooling to -35.degree. C., then compressed in a screw compressor with oil injection to 1.5 MPa, the oil is separated off, freed from gel-containing residues through a filter web and again recycled into the compressor. The compressed hydrogen chloride gas is fractionated in a distillation column under pressure and hydrogen chloride having a purity of 99.999 percent is recovered.
