Definitions
- the invention relates to a process for the preparation of multimetal cyanide compounds, also referred to as DMC catalysts.
- DMC catalysts are used in the preparation of polyether alcohols by addition of alkylene oxides to H-functional starter substances, especially alcohols.
- the space-time yield in the production can be increased.
- the polyether alcohols produced by this process are characterized by a reduced content of unsaturated constituents.
- the preparation of DMC catalysts is usually carried out by reacting a hexacyanometallate compound, preferably hexacyanocobaltate or hexacyanocobaltic acid, with a metal salt.
- a hexacyanometallate compound preferably hexacyanocobaltate or hexacyanocobaltic acid
- metal salt preferably hexacyanometallic acids
- hexacyanometallic acids are usually prepared by means of ion exchangers, as described in EP 862 997.
- a Hexacyanometallatsalz is dissolved in water and acidified with sulfuric acid.
- an organic solvent for example methanol, is added, which leads to the precipitation of potassium sulfate.
- This is filtered off and the thus obtained solution of Hexacyanometallatklare by combining with an aqueous solution of the metal salt component to the D MC catalyst reacted.
- ligands and / or organic additives may be present or added.
- This process represents an alternative to the recovery of hexacyanometallic acid by ion exchange.
- Removal of potassium sulfate by filtration, like ion exchange, is an additional process step, in this case even involving the handling of a solid
- an organic solvent must be used for precipitation, which leads to additional costs and it can not be ruled out that at least some of the salt formed remains in the catalyst.
- WO 99/56874 describes a catalyst which is treated with a protic acid. The addition of the acid occurs during or after the catalyst synthesis, but in any case only after the precipitation of the metal salt DMC compound and cyanometalate component. Polyetherols having a reduced high molecular weight fraction can be prepared with these catalysts.
- the processes described require an additional process step of treating the precipitated DMC compound with a mineral acid. If the acid remains in the DMC catalyst as described in US Pat. No. 4,477,589, corrosion problems may arise, for example with hydrochloric acid, which is described as being preferred in US Pat. No. 4,477,589. So you have to design the reactors for polyol production corrosion resistant, which leads to higher costs. Furthermore, it can not be ruled out that the acid which has only been adsorbed on the DMC catalyst and thus becomes more volatile passes into the product prepared by means of DMC catalyst. For chlorine-containing acids, this could be problematic due to the possible formation of organochlorine compounds. For example, it can not be ruled out that the hydrochloric acid catalyzes an ether cleavage and thus an undesired reaction, in which organochlorine compounds in turn could also be formed.
- the object of the present invention was to find a simplified process for the preparation of DMC catalysts, which leads to DMC catalysts having a high catalytic activity.
- DMC catalysts having a high catalytic activity can be obtained when the reaction of the cyanometallate compound with the metal salt takes place in the presence of a Bronsted acid.
