    摘要: A flow-promoting device in combination with a heated box tray open at the top in a reaction and degasification column in which a viscous or highly viscous liquid is flowing from an inlet end to an outlet end of the tray and in which a heating tube register is located to be completely covered by the liquid. The tube register includes a plurality of heating tubes spaced from each other, and the flow-promoting device has a bottom heating unit for the box tray positioned outside and along the bottom of the tray, a siphon plate mounted on the tray at a liquid inlet end of the tray and closely in front of the tube register, with the siphon plate having a bottom end extending to the underside of the tube register, and a weir positioned at the liquid outlet end of the box tray. The weir has a top edge extending at least to the topside of the tube register, and the spacing of the weir from the tube register is larger than the spacing of the siphon plate at the inlet end from the tube register.

    摘要: The invention relates to a process for preparing vinyl chlorosilanes, that includes thermally and non-catalytically reacting chlorosilane with vinyl chloride at a temperature of 550 to 700° C. by flowing the chlorosilane and vinyl chloride through a ring-gap space in a ring-gap reactor to produce a reaction gas; the ring-gap space having a cross-sectional area and a volume; and, after the flowing, further reacting, adiabatically, the reaction gas in a second zone to produce a hot reaction gas that contains vinylchiorosilane; wherein the second zone has a cross-sectional area that is greater than the cross-sectional area of the ring-gap space; and wherein the second zone has a volume that is in a ratio to the volume of the ring-gap space of 0.15:1 to 1.5:1. The invention also provides an apparatus for carrying out the above process.
