    1441457 Halogenated hydrocarbon HOECHST AG 22 June 1973 [24 June 1972] 29738/73 Heading C2C [Also in Division B1] Halogenated hydrocarbon is prepared by a method which comprises contacting, for example at a temperature of from 400 to 800‹ C. and a pressure of from 50 to 700 kp/cm<SP>2</SP>, hydrocarbon/ partially halogenated hydrocarbon/completely halogenated hydrocarbon with halogen in a reactor which comprises a plurality of seriesconnected reactor units each comprising a body portion having a nickel lining flanged at its end (or ends) connected to another reactor unit (or other reactor units) and, between each adjacent pair of reactor units, a sealing element comprising a nickel core which is in sealing contact with the adjacent flange of the lining of each reactor unit adjacent thereto. General reference is made in the specification to the "chlorolysis" reaction, i.e. the splitting of C-C bonds by the action of chlorine at elevated temperature and pressure, and to the fact that the product of this reaction may comprise material selected from hydrogen chloride, carbon tetrachloride and tetrachloroethylene; specific reference is made to the formation of carbon tetrachloride from benzene and chlorine. As exemplified, reaction product comprising non-reacted chlorine, hydrogen chloride, carbon tetrachloride, hexachloroethene and hexachlorobenzene is obtained from a combination of 1,2-dichloroethane and residue resulting from chlorination of methane to form carbon tetrachloride and containing carbon tetrachloride, pentachloroethane, hexachloroethane, trichloroethylene and tetrachloroethylene (Example 1) and from residue resulting from vinyl chloride manufacture and containing 1,2-dichloroethane, 1,1,2-trichloroethane, dichlorobutene and monochlorobenzene (Example 2) by reaction with chlorine in such reactor.

    专利说明:

    This invention relates to the field of reaction at high pressures and temperatures with corrosive materials.
    ia most closely related to the invention is a reactor comprising a vertical cylindrical body, a lining located on the inner surface of the body, flanges with flange of the lining sandwiched between them, sealing elements 1 and fasteners 1.
    The disadvantage of this reactor is insufficient strength when conducting reactions at high pressures and temperatures in corrosive environments.
    The aim of the invention | And is to conduct chemical reactions at a temperature of 400-800 ° C and a pressure of 50-700 atm.
    This goal is achieved by having annular undercuts at the ends of the reactor tubes, and the lining at the ends of the pipes is made with flanging, which is located in the recesses and clamped by sealing rings, and the lining and sealing rings are made of nickel nickel.
    FIG. 1 shows the proposed reactor, a longitudinal section; in fig. 2 - connection of two reactor parts
    sealing element with fitting, longitudinal section.
    The reactor contains a pressure-resistant case /, made of heat-resistant steel: 1, a screwed flange 2, also made of heat-resistant steel, nickel lining 3, flanged at both ends. The flanging is in the recesses so that the nickel flanging protrudes only slightly above the steel jacket. All nickel flanging before assembly, it is advisable to carefully grind at an angle and in such a way as to obtain a flat sealing surface.
    The reactor also includes a nozzle for product outlet 4, a cylindrical nickel core seal 5 surrounded by two flange rings 6, 7, screws 8, tube elements 9 of heat resistant steel, the ends of which are provided with an external thread, screwed flanges 10, of heat resistant steel, screws //, nuts 12, made of heat-resistant steel. Between the flange ring-ring 6 7 and the nuts 12 there is one pl or several cup springs 13 made of heat-resistant spring steel. Preferably, under each nut there are several cup springs which
    it is advisable to center by pushing on the sleeves 14. The arrangement described is repeated one or more times along the length of the reactor.
    The housing 1 has a groove on the side of the flange, which is made so deep that the nickel lining protrudes only slightly above the steel. The flanging extends up to a diameter larger than the diameter of the contact line of the body (or pipe) and the nickel core. The sealing surfaces of the nickel core are easily convex; they are, in their design, parts of a spherical surface with a large ball diameter, the center of which lies in the axis. The flaring of nickel linings is dried in each case at an angle a, which is expediently 70 °, tangent on the curved sealing surfaces on the nickel core has an angle p (90 ° -a) to the perpendicular axis of the reactor, 20 ° .- Pipe elements 9 are independent of each other, heaters 15, 16, preferably in the form of surrounding electrical heating elements.
    Agree to FIG. 2 nickel core 5 is connected, for example, with one nickel fitting 17; perpendicular to the nickel friend.
    Nickel cores and choke 15, 17 may also consist of a nickel billet alone. The fitting 17 is surrounded by a heat-resistant steel ring 18, which has a cylindrical collar of large diameter on the side directed to the center. Both flange rings b and 7 have a recess, which fixes ring 18 and thereby
    slipping is prevented. On the outer side, a flange 19 is screwed on a ring 18 with an external thread. In the sealing element there may be
    located by the described method and several chokes.
    With the help of the reactor according to the invention proposed in this invention, for the first time it was possible to reliably and on a technical scale to carry out the described kind of reaction at high outputs in terms of volume and time.
