Definitions
- the invention relates to a process for the preparation of multimetal cyanide compounds.
- Multimetal cyanide compounds often referred to as DMC catalysts, have long been known and widely described in the literature, for example, in US 3,278,457 and in US 5,783,513.
- Such compounds are preferably used as catalysts for the preparation of polyether alcohols by addition of alkylene oxides to H-functional starter substances. These methods are also known.
- the preparation of the multimetal cyanide compounds is usually carried out by reacting the aqueous solution of a metal salt with the aqueous solution of a cyanometalate, often in the presence of at least one organic ligand.
- the multimetal cyanide compound thus obtained is separated, washed and dried.
- WO 01/39883 describes a process for the preparation of multimetal cyanide compounds in which a metal salt solution is combined with the solution of a hexacyanometallate compound in a mixing nozzle.
- the disadvantage here is that particle formation may already occur in the nozzle, resulting in Pressure loss in the nozzle leads to blockages.
- WO 2006/037541 describes a process for the continuous preparation of multimetal cyanide compounds in a continuously operated stirred tank. Again, there may be blockages, especially in the discharge of Multimetallcyanidimplen from the stirred tank.
- the object of the present invention was to develop a simple and economical process for the continuous production of multimetal cyanide compounds. The process should be easy to carry out and ensure good and reproducible product quality.
- the solution to this problem is a process for the continuous preparation of multimetal cyanide compounds by reacting the aqueous solutions of a metal salt with a HexacyanometallatENS, the mixture flows over the surface of a rotating body A to an outer region of the surface of the rotating body A and thrown off therefrom becomes.
- the invention relates to a process for the preparation of multimetal cyanide compounds by reacting the aqueous solution of a metal salt a) with the aqueous solution of a Hexacyanometallattagen b), characterized in that the mixture of the solutions a) and b) on the surface of a rotating body A to a outer region of the surface of the rotating body A flows and is thrown off therefrom.
- the rotating body A may be designed as a disk, vase, ring or cone, wherein a horizontal or a horizontal deviating from the horizontal by up to 45 ° C turntable is to be regarded as preferred.
- the body A has a diameter of 0.10 m to 3.0 m, preferably 0.20 m to 2.0 m, and more preferably from 0.20 m to 1, 0 m.
- the surface may be smooth or have, for example, rippled or spiral-shaped indentations which influence the mixing and the residence time of the reaction mixture.
- the body A is expediently installed in a container which is resistant to the conditions of the method according to the invention.
- the rotational speed of the rotating body A and the metering rate of the mixture are variable. Typically, the rate of revolution in revolutions per minute is from 1 to 20,000, preferably 100 to 5,000, and more preferably 200 to 3,000.
- the volume of the reaction mixture which is per unit area of the surface on the rotating body A, is typically 0.03 to 40 mL / dm 2 , preferably 0.1 to 10 mL / dm 2 , more preferably 1, 0 to 5.0 mL / dm 2 .
- the mean residence time (frequency spectrum of the residence time spectrum) of the mixture depends inter alia on the size of the surface, the type of compound and the amount of water contained, the temperature of the surface and the rotational speed of the rotating body A and is normally between 0, 01 and 60 seconds, more preferably between 0.1 and 10 seconds, in particular 1 to 7 seconds and is thus to be regarded as extremely short. This ensures that the extent of possible decomposition reactions and the formation of undesirable products is greatly reduced and thus the quality of the substrates is maintained.
- the preparation of the multimetal cyanide compound is carried out by means of an apparatus which ⁇ ) one about a preferably centrally disposed axis of rotation
- the surface extends to further rotating bodies, so that the mixture passes from the surface of the rotating body A to the surface of at least one further rotating body.
- the other rotating bodies are suitably designed according to the body A.
- body A then feeds the other bodies with the reaction mixture.
- the reaction mixture leaves this at least one other body, and can then be cooled by means of the quencher, if necessary.
- the mixture is present on the surface of the rotating body A in the form of a film having an average thickness between 0.1 ⁇ m and 6.0 mm, preferably between 60 and 1000 ⁇ m and in particular 100 and 500 ⁇ m ,
- the temperature of the rotating body A in particular of the surface facing the mixture, can be varied within wide ranges and depends both on the substrates used, the residence time on the body A and on the pressure. Temperatures between 5 and greater than 100 ° C., particularly preferably between 25 and 120 ° C., in particular between 25 and 90 ° C., have proven to be expedient.
- the mixture applied to the body A and / or the rotating body A can, for example, be heated electrically, with a heat transfer fluid, with steam, with a laser, with microwave radiation or with infrared radiation.
- the process according to the invention can be carried out under normal pressure or slight overpressure and in an atmosphere of dry protective gas. However, it may also be expedient to generate a vacuum, wherein overall pressures between 0.01 mbar and 1 100 mbar, more preferably between 1 mbar and 500 mbar, in particular between 10 mbar and 400 mbar, have proved to be advantageous.
- a preferred embodiment of the present invention further provides that the evaporated water is expelled with a gas or dry air, in particular inert gas.
- the multimetal cyanide compounds prepared by the process according to the invention preferably have the general formula (I)
