Definitions
- the processes consist of a two-stage process with reactors connected in series. This makes reaction management in discontinuous operation inefficient.
- the catalytic converter ages after a long period of operation and, over time, requires ever higher operating temperatures, which in turn has an unfavorable effect on the composition of the product gas: the back reaction of carbonyl dichloride to chlorine and carbon monoxide increases noticeably, which necessitates expensive gas scrubbing.
- the activated carbon catalyst itself triggers side reactions.
- the relatively long contact time of chlorine on large activated carbon surfaces at elevated temperatures causes the formation of carbon tetrachloride, which e.g. in the polycarbonate production as a toxic by-product, and is also harmful to the environment. Concentrations around 400 ppm carbon tetrachloride and above are typical.
- a new process involves the production of carbonyl dichloride from bis (trichloromethyl) carbonate.
- the production from chlorine and carbon monoxide is still important.
- the task is to design the process so that a one-step process is possible and the reaction parameters pressure and temperature can be varied over a wide range, so that a maximum of elasticity in the process control of the process can be achieved and disruptive accompanying products such as carbon tetrachloride are minimized.
- the main advantage of the invention is that on metal halides, without activated carbon, at room temperature and significantly below, chlorine and carbon monoxide produce quantitatively pure carbonyl dichloride.
- the catalyst can be pure or applied to a support material.
- the process can be carried out continuously or batchwise.
- the pressure during the reaction can range from normal pressure to 100 bar, a slight excess pressure of 0.2 to 15 bar has proven to be advantageous.
- the process works unexpectedly at temperatures from -30 ° C to 300 ° C, preferably 0 ° C to 100 ° C.
- Suitable catalysts are metal halides, preferably metals from the 3rd main group of the Periodic Table of the Elements.
- Aluminum chloride and the gallium chlorides Ga (II) and Ga (III) chloride are particularly suitable. The latter far outperform aluminum chloride in reactivity.
- Mixed halides made of metal alloy components are also very suitable as catalysts.
- a particular advantage of the process is the absence of activated carbon as a catalyst, because it causes the formation of carbon tetrachloride or other chlorinated Compounds that can interfere in further reactions and / or can have highly damaging properties, cannot occur at all from the reaction of chlorine with activated carbon.
- Another advantage of the process is the scalability of the process. It is possible to transfer an embodiment to practically any size.
- the method allows automatic regeneration of the metal halide catalyst by keeping it constantly active during the reaction by means of continued sublimation.
- reaction chamber (4) which consists of a glass tube
- the pressure holding valve (5) which is set to 0.3 bar overpressure, connects to the reaction chamber (4). From this the product stream enters the condensation room (6), where the product is liquefied at -20 ° C. The system is terminated by a bubble counter (7) with virtually no counter pressure.
- the chlorine / carbon monoxide gas flow is set via (1) and (2) so that no gas flow emerges via (7).
- the condensate in (6) is identified as pure carbonyl dichloride (GC).
