Definitions
- the present invention relates to a process for the preparation of alkenylhalogeno-silanes, in particular of vinyltrichlorosilane from vinyl chloride and trichlorosilane, as well as a particularly suitable reactor.
- the industrial production of alkenylhalosilanes is well known.
- Alkenylhalosilanes such as vinyltrichlorosilane (III), in particular the group consisting of
- Compound (III) vinyltrialkoxysilanes prepared via esterification reactions are important intermediate or intermediate technical products in organosilane chemistry. They are used, for example, as crosslinkers in plastics such as PVC, PP and PE.
- Trichlorosilane is typically carried out in a high-temperature reactor in the temperature range between 400 and 700 ° C and a pressure between 1 and 2 bar abs.
- the common methods are characterized in that either a tubular reactor or a reactor with a
- rotating displacer is used. Examples of this can be found in EP 0 438 666 A2, DE 199 18 1 14 A1 and DE 199 18 1 15 A1.
- EP 0 438 666 A2 describes an annular gap reactor with a gap of 20 mm.
- the annular gap is formed via a rotating displacement body within the reactor shell.
- the documents DE 199 18 1 14 A1 and DE 199 18 1 15 A1 describe an annular gap reactor for the production of vinyltrichlorosilane, in which, after flowing through the annular gap, an adiabatic reaction zone is passed through and subsequently the
- Silicon tetrachloride 38.1 kg / h of high boiler / more
- Silicon tetrachloride 20.8 kg / h high boiler / more
- the production output of the described ring-gap reactor is 100 t of vinyltrichlorosilane per month or specifically as space-time yield 648 kg / (m 3 * h).
- Object of the present invention is to provide a method and a suitable reactor for the production of Alkenylhalogensilanen with over known Processes and reactors increased yield and selectivity and with a reduced tendency to side reactions.
- the present invention relates to a process for the preparation of alkenylhalogenosilanes by reacting alkenyl halide selected from the group of vinyl halide,
- Vinylidene halide or halide-halide allyl halide selected from the group consisting of mono- and di-o-trihalosilane in the gaseous phase in a reactor comprising a reaction tube (1) equipped with one inlet (2) at one end of the tube and one outlet (3) at the other end of the tube; an annular gap nozzle (4) having a central feed (5) for one reactant (7) and a feed (6) surrounding the central feed (5) for the other reactant (8) and attached to the inlet (2) and in that
- Reaction tube (1) opens, wherein alkenyl halide are injected through the central feed (5) and halosilane through the surrounding feed (6) in the reaction tube (1) and in the direction of outlet (3) through the reaction tube (1).
- halogen is to be understood as meaning fluorine, chlorine, bromine or iodine, preferably chlorine and bromine, in particular chlorine.
- the vinyl halides used according to the invention are vinyl fluoride, vinyl chloride, vinyl bromide and vinyl iodide or mixtures of two or more thereof. Preference is given to using vinyl chloride and / or vinyl bromide, very particularly preferably vinyl chloride.
