    摘要: The present invention relates to a process for the continuous preparation of diaryl carbonates from phosgene and at least one monohydroxy compound (monophenol) in the presence of catalysts, and also the use thereof for preparing polycarbonates. The hydrogen chloride formed in the reaction is converted by thermal oxidation into chlorine, with the chlorine being recirculated to the preparation of phosgene. In particular, the process comprises utilization of the hydrogen chloride formed for the process for preparing diphenyl carbonate (DPC process).

    摘要: Low-pressure, mercury vapor discharge lamp has at least two dual-shaped lamp parts (1; 2; 3), each comprising a first and a second tube (11,21,31; 12;22;32). The first and second tube are interconnected via tube interconnection means (10; 20; 30) at a first end portion (11a, 12a;21a, 22a;31a,32a). A discharge path is formed through the tubes between two electrodes (13; 33). Each electrode is provided at a second end portion (11b; 32b) of one of the tubes (11; 32). Further second end portions (12b; 21b; 22b; 31b)are provided with respective sealed ends (12c; 21c; 22c; 31c). Bridge parts (50; 60) for interconnecting tubes (12,21; 22,31) of mutually adjacent dual-shaped lamp parts (1,2; 2,3) are provided in the proximity of the second end portions (12b,21b; 22b,31b). At least one of the sealed ends (21c) is provided with an exhaust tube (71) which is directly provided on the respective sealed end.
