Definitions
- the invention relates to a process for the preparation of polyether polyols.
- Polyether polyols are widely available, especially for the production of polyurethane foams.
- the known production processes for polyether polyols are generally carried out from alkylene oxides in the presence of a short-chain starter using various catalysts, such as bases, hydrophobized double-layer hydroxides, acidic or Lewis acid systems, organometallic compounds or multimetal cyanide complex compounds.
- Heterogeneous multimetal cyanide complex catalysts are highly selective and active catalysts which are particularly suitable for the production of flexible foam polyether polyols in which a high molecular weight has to be achieved and in which long oxalkylation times are required.
- multimetal cyanide complex catalysts the production costs can be reduced and at the same time high-quality polyether polyol, which can be processed into low-odor and thus high-quality polyurethane foams, can be obtained. It is known from the literature that side reactions which can lead to the formation of odorous substances and unsaturated constituents hardly occur.
- EP 850 954 describes a process in which the reaction takes place in the gas space above the liquid.
- the polyether polyol is pumped in a circle through a heat exchanger and fed through nozzles. This results in a high liquid surface.
- ethylene oxide and polyether polyol are metered in via nozzles. The large surface area ensures good mass transfer and thus high reaction rates.
- EP-B-0 633 060 discloses a reactor for gas-liquid reactions with a central stirring device, around which heat exchanger plates through which a heat exchange medium flows are arranged at an angle of 0 to 70 ° in the direction of rotation of the stirrer to the reactor radius. Due to the direct heat dissipation at the point of its creation, increased productivity, high product quality and reduced catalyst consumption can be ensured.
- the reactor of EP-B-0 633 060 has been proposed in particular for strongly exothermic catalytic hydrogenation reactions.
- the solution is based on a process for the preparation of polyether polyols by reacting diols or polyols with ethylene oxide, propylene oxide, butylene oxide or mixtures thereof in the presence of a multimetal cyanide complex catalyst in a stirred tank reactor.
- the invention is characterized in that the reaction mixture is circulated by means of a pump via an external heat exchanger.
- stirred tank reactors There are no restrictions with regard to the stirred tank reactors that can be used. Vertical, in particular cylindrical, reactors with preferably a central stirrer are preferably used.
- the starting materials are fed into the liquid reaction mixture in the stirred tank.
- the reaction mixture is circulated by means of a pump via an external heat exchanger.
- Different types of pumps can be used to circulate the reaction mixture.
- a screw pump is particularly preferably used for this purpose.
- the spindles form sealed chambers due to the special profile design of the thread flanks, the content of which is shifted axially and completely continuously from the suction to the pressure side of the pumps when the spindles rotate.
- Screw pumps have the advantage that their delivery rate is largely independent of the viscosity changing in the course of the reaction. Adequate heat dissipation can be ensured at any time during the reaction.
- the heat exchanger is particularly preferably in the form of plates or spirals. Spiral heat exchangers offer the advantage that they place little mechanical stress on the catalytic converter. This type of heat exchanger is therefore also used for the production of dispersions.
- the delivery rate of the pump is preferably set so that the reactor contents are circulated 5 to 100 times per hour, preferably 20 to 50 times per hour.
- the concentration of the multimetal cyanide complex catalyst in the reaction mixture is preferably set in a range, based on the total amount of product obtained in the reactor, of ⁇ than 250 ppm, preferably ⁇ than 100 ppm, particularly preferably ⁇ than 50 ppm.
- the process is particularly preferably carried out in a semi-batch mode, i.e. Starter and catalyst are introduced and the alkylene oxides are metered into the reactor. The heat of the reactor is removed in order to be able to control the reaction temperature.
- the reaction is preferably carried out at temperatures in the range from 80 to 200 ° C. and a pressure from 1 to 100 bar.
- the reaction is particularly preferably carried out at a temperature in the range from 90 to 160 ° C. and a pressure from 2 to 20 bar.
- Multimetal cyanide complex catalysts of the general formula (I) are particularly preferred used in the M 1 at least one element from the group consisting of Zn (II), Fe (II),
- M is at least one element from the group consisting of Fe (II), Fe (III) .
- L 1 at least one ligand from the group consisting of cyanide, carbonyl,
- X is a formate anion, acetate anion or propionate anion
- L 2 at least one water-miscible ligand from the group consisting of alcohols. Aldehydes, ketones, ethers. Polyethers, esters. Urea derivatives, amides, nitriles and sulfides, a, b, d, e, f, g, whole or fractional numbers greater than zero and c, h, i whole or fractional numbers equal to or greater than zero, where a, b, c and d are chosen so that the electroneutrality condition is fulfilled and f and g are chosen so that the electroneutrality condition is met, whose X-ray diffractogram shows reflections at at least the d values
- X is a propionate anion or have a monoclinic crystal system if X is an acetate anion.
- the multimetal cyanide complex catalyst used is particularly preferred of the zinc-cobalt type.
- the viscosity was determined in accordance with DIN 51 550.
- the content of unsaturated constituents was determined using the iodine number.
- the unsaturated portions were brominated in a first process step, excess bromine was reacted with potassium iodide solution with the precipitation of iodine.
- the content of unsaturated constituents in milliequivalents / g (meq / g) was determined by titration of the precipitated iodine with thiosulfate solution.
- a polyether polyol was prepared by alkoxylating a polypropylene oxide prepolymer with an average molecular weight of 400 g / mol with propylene oxide.
- KOH as a catalyst in a stirred tank reactor with internal cooling coils led to a symmetrical molecular weight distribution without high molecular weight components.
- the result was a viscosity of the processed (neutralized) product of 495 mPas (25 ° C.), a content of unsaturated constituents of 0.061 meq / g and a cycloacetal content of 1.7 ppm.
- a space-time yield of 105 kg / m 3 / h was achieved.
- a multimetal cyanide complex catalyst of the Zn-Co type was used, which was produced in a two-stage process, after which the acid and then the catalyst were obtained by precipitation.
- the ion exchanger was then converted to the acid form by passing 10% hydrochloric acid at a rate of 2 bed volumes per hour over the exchange column for 9 hours until the sodium content in the discharge was ⁇ 1 ppm.
- the ion exchanger was then washed with water.
- the regenerated ion exchanger was then used to produce a substantially alkali-free hexacyanocobaltic acid.
- a 0.24 molar solution of potassium hexacyanocobaltate in water was passed over the ion exchanger at a rate of one bed volume per hour. After 2.5 bed volume, the potassium hexacyanocobaltate solution was changed to water.
- the 2.5 bed volumes obtained had an average content of 4.5% by weight of hexacyanocobaltic acid and alkali contents ⁇ lppm.
- the solid thus obtained was then filtered off and washed with 6 times the cake volume was then dispersed in polypropylene glycol with a molecular weight of 400 g / mol.
- the dispersion thus obtained was used as a catalyst.
- the reaction was carried out in a stirred tank reactor with jacket cooling. After the catalyst had been added, the mixture was dewatered in vacuo and propoxylated for 1 h. A symmetrical molecular weight distribution without high-molecular components resulted.
- the viscosity was 827 mPas at 25 ° C.
- the content of unsaturated components was only 0.0062 and the cycloacetal content was 0.05 ppm.
- the space-time yield achieved was 220 kg / m 3 / h.
- Comparative example 3 was repeated, but repeated in a stirred tank reactor with an external heat exchanger. As in Comparative Example 3, there was a completely symmetrical molecular weight distribution without high molecular weight components. The viscosity was 595 mPas at 25 ° C. The content of unsaturated components was 0.0061 and the cycloacetal content was 0.04 ppm. The space-time yield achieved was 290 kg / m 3 / h. Thus, a higher space-time yield and at the same time an improvement in the product quality was achieved by using an external heat exchanger.
