- the invention further relates to a process for the preparation of 1,2 dichloroethane by oxychlorination of ethylene, characterized by the reaction of a mixture of ethylene, oxygen or oxygen-containing gas and hydrogen chloride to 1,2-dichloroethane by means of a catalyst of the above composition.
- Oxychlorination of ethylene to 1,2-dichloroethane is a well known process in which ethylene is reacted with hydrogen chloride and oxygen or with an oxygen-containing gas (e.g. air) in the gas phase and usually in the presence of a catalyst.
- Suitable catalysts generally contain as a catalytically active component a copper compound which has been deposited on a carrier substance, preferably copper chloride on a carrier substance.
- the supported catalysts used therefore usually contain what are known as promoters, by means of which the effectiveness of catalytically active copper chloride on supported substances is improved.
- promoters include alkali metal chlorides, in particular potassium chloride and cesium chloride, alkaline earth metal chlorides, in particular magnesium chloride, or else chlorides of rare earth metals, in particular cerium chloride.
- alkali metal chlorides in particular potassium chloride and cesium chloride
- alkaline earth metal chlorides in particular magnesium chloride
- chlorides of rare earth metals in particular cerium chloride.
- EP-A 0 582 165 describes a catalyst composition comprising a support which has an active metal composition which contains 2 to 8% by weight of copper as copper chloride, 0.2 to 2% by weight of an alkali metal, 0.1 to 9 wt .-% of a rare earth metal and 0.05 to 4 wt .-% of a metal from group ILA of the periodic table (alkaline earth metals).
- EP-A 0 375 202 discloses a catalyst composition for oxychlorination, comprising a mixture of metal chlorides on a support, which essentially contains a mixture of copper chloride, magnesium chloride and potassium chloride in such proportions that the catalyst composition 3 to 9% by weight of copper, 0.2 to 3% by weight of magnesium and 0.2 to 3% by weight of potassium.
- No. 4,446,249 describes a catalytically active composition for a fluidized bed catalyst in which, on the carrier substance ⁇ -Al 2 O 3 , before the copper chloride is deposited, 0.5 to 3% by weight of at least one metal from the group potassium, lithium , Rubidium, cesium, alkaline earth metals or rare earth metals or mixtures of these elements are deposited.
- the catalytically active copper chloride is then deposited on the carrier particles.
- This two-step application of the active metal components to the carrier substance means that the catalyst particles produced by this process have less tendency to adhere to one another. This property is particularly advantageous when the catalyst is used as a fluidized bed.
- the selectivity with which ethylene is converted in the oxychlorination reaction into the desired end product 1,2-dichloroethane - and not into the by-products customary in oxychlorination - is strongly dependent on the catalyst composition used. Especially in reactions with high ethylene conversion, too many by-products are still obtained when using the catalyst compositions which have been customary to date.
- Fluidized bed catalysts for the oxychlorination of ethylene to 1,2-dichloroethane must therefore not only be optimized in terms of activity and selectivity, but also have a "sticking" -free swirl behavior. It can be observed that copper-rich catalysts have a greater tendency to stick together than low-copper catalysts.
- a catalyst composition for the oxychlorination of ethylene comprising a mixture of metal salts on a support, said metal salts being applied to the support in such proportions that the catalyst composition
- % preferably 0.005 to 0.05% by weight, of at least one metal selected from the group consisting of ruthenium, rhodium, palladium, osmium, iridium and platinum and / or 0.0001 to 0.1% by weight, preferably 0.001 to 0.05% by weight of gold, as a corresponding metal salt or tetrachlorogoldic acid, comprises, wherein all weight percentages are based on the total weight of the catalyst including support material.
- the presence of small amounts of a salt of the platinum metals, which include ruthenium, rhodium, palladium, osmium, iridium and platinum, or the presence of small amounts of corresponding gold compounds in the catalyst composition used increase the conversion of the starting materials ethylene and hydrogen chloride significantly, but without to reduce the selectivity for the formation of 1,2 dichloroethane. This ultimately results in a higher yield of 1,2 dichloroethane.
- the fluidization behavior is not influenced by the addition of small amounts of the metal salts mentioned above.
- the corresponding oxyhalides, the oxides or the halides of the platinum metals or gold, in particular the chlorides of the platinum metals or gold are preferably used as the metal salts of the platinum metals or gold.

- Ethylene, hydrogen chloride and molecular oxygen are brought into contact with a catalyst composition according to the invention at temperatures from 80 to 300 ° C., preferably at 210 to 260 ° C. in the gas phase.
- the molecular oxygen can be used as such or in the form of an oxygen-containing gas mixture, e.g. Air to be discharged.
- an oxygen-containing gas mixture e.g. Air to be discharged.
- the molar ratios of the starting materials used in the process according to the invention are generally 5: 1 to 3: 1 for hydrogen chloride: oxygen, preferably approximately 4: 1 and generally approximately 1: 2 for ethylene: hydrogen chloride.
- Hydrogen chloride based on the reaction 2 C 2 H 4 + 4 HC1 + O 2 a 2 C 2 H 4 CI 2 + 2 H 2 O, in slightly sub-stoichiometric amount, so that it is ensured that hydrogen chloride is converted almost completely in one reactor run.
