- Polyaryl ether ketones and their use are known in the prior art.
- polyether ether ketones from the group of polyaryl ether ketones are used as or in polymer electrolyte membranes.
- These polyether ether ketones are functionalized in such a way that they are capable of ion exchange and preferably of taking up and releasing protons.
- the - COOH and -SO 3 H groups in particular should be mentioned as functional groups.
- the prior art describes, for example, oleum, concentrated sulfuric acid or sulfur trioxide in a suitable organic solvent as sulfonation reagents for polyaryl ether ketones.
- Lithography using butyllithium, reaction with sulfur dioxide and subsequent oxidation with, for example, potassium permanganate is also known.
- DE 100 47 551 A1 discloses the use of sulfonated polyether ether ketones as proton-exchanging membranes, the use of the membranes preferably being described in direct methanol fuel cells.
- the sulfonation of the polyether ether ketone is carried out using sulfur trioxide, sulfuric acid or trimethylsilylsulfonyl chloride.
- EP 574 791 A2 describes the sulfonation of polyaryl ether ketones using sulfonic acid.
- the sulfonated polymer is used, among other things, in fuel cells as an electrolyte membrane.
- Nafion® is functionalized using gas phase sulfonation.
- JP 2001233974 A2 describes the sulfonation of films which in turn are produced from heat-resistant and imide bond-containing polymers and which are used as ion exchange membranes in fuel cells, for example.
- the sulfonation is achieved by immersing the film in sulfuric acid.
- JP 2001325970 A2 describes the use of alkanesulfonic acids such as, for example, methanesulfonic acid in electrolyte membranes which are used in fuel cells. There it is described that an already sulfonated polymer matrix is impregnated with methanesulfonic acid, phosphoric acid or sulfuric acid, which act as a liquid electrolyte, to produce the membranes.
- alkanesulfonic acids such as, for example, methanesulfonic acid in electrolyte membranes which are used in fuel cells.
- JP 2000294033 A2 discloses the production of proton-conducting DNA membranes which can be used in fuel cells, DNA membranes in polar organic solvents containing strong acids such as methanesulfonic acid, ethanesulfonic acid, phosphoric acid or sulfuric acid are immersed. This immersion loads the strong acid in the DNA membrane.
- DE-A 101 16 391 discloses sulfonated amorphous polyether ketone ketones (see PEKK). The sulfonation is carried out using diphenyl ether and benzenedicarboxylic acid derivative, preferably benzenedicarboxylic acid dichloride. According to DE-A 101 16 391, the degree of sulfonation of the amorphous polyether ketone ketones used is adjustable.
- the term “low degrees of sulfonation” means degrees of sulfonation of less than 60% and in particular less than or equal to 55%.
- the term “degree of sulfonation” relates to the number of sulfonic acid groups per repeating unit of the polyaryl ether ketone calculated from the sulfur content determined by means of elemental analysis.
- a “degree of sulfonation” of 100% here denotes a sulfur-containing polyaryl ether ketone, which has a “sulfonic acid group” per statistical unit on average.
- An exact setting of the “degree of sulfonation” means a setting which generally deviates from the desired degree of sulfonation by a maximum of +/- 5%, preferably a maximum of +/- 2%.
- One object of the present invention is to provide a method by which it is possible to achieve degrees of sulfonation over a wide range, for example in the range from 10 to 90%, and for example preferably also low degrees of sulfonation while maintaining simple parameters such as temperature, reaction time and Targeted concentration of sulfonation reagent.
- a targeted adjustment of the degree of sulfonation of polyaryl ether ketones is important, since polyaryl ether ketones with a very high degree of sulfonation are water-soluble and polyaryl ether ketones with a very low degree of sulfonation are poorly ion-conducting. For preferred use as membranes in fuel cells, however, it is desirable to provide water-insoluble but good ion-conducting polyaryl ether ketones. These can be obtained by a specific degree of sulfonation.
- the present invention relates to a process for the preparation of sulfonated polyaryl ether ketones, comprising the step (i):
- polyaryl ether ketones are used together in the process according to the invention, it is conceivable that only one of the polyaryl ether ketones is sulfonated. Two or more can also be sulfonated. In principle, all polyaryl ether ketones that are accessible to sulfonation via alkanesulfonic acids can be used as polyaryl ether ketones.
- Suitable polyaryl ether ketones are the polyaryl ether ketones of the formula I mentioned in EP-A 0 574 791, and polyaryl ether ketones of the formulas IV, V and VI which are preferably used in EP-A 0 574 791.
- the preferred polyaryl ether ketones used in the context of the present invention are polyether ether ketones, polyether ketones, polyether ketone ketones. Suitable compounds of these groups are known to the person skilled in the art. Polyether ether ketones and polyether ketones are further preferred.
- the PEEK TM and PEK TM polymer types (from Victrex plc), in particular PEEK TM 450P, PEEK TM 150P and PEK TM P22, are very particularly preferably used.
- Aliphatic sulfonic acids are generally suitable as alkane sulfonic acid in step (i). Alkanesulfonic acids of the general formula are preferred
- R is a hydrocarbon radical which can be branched or unbranched, having 1 to 12 carbon atoms, preferably having 1 to 6 carbon atoms, particularly preferably an unbranched hydrocarbon radical having 1 to 3 carbon atoms, very particularly preferably having 1 carbon atom, that is to say methanesulfonic acid
- the present invention also relates to a method as described above, which is characterized in that the alkanesulfonic acid Methanesulfonic acid and the at least one polyaryl ether ketone is a polyether ether ketone.
- At least one alkanesulfonic acid or a mixture of different alkanesulfonic acids is used as the solvent.
- the alkanesulfonic acid used in step (i) for the reaction with the polyaryl ether ketone is preferably used, particularly preferably methanesulfonic acid. This means that preferably the at least one alkanesulfonic acid itself acts as a solvent. Suitable alkanesulfonic acids are mentioned above.
- the at least one polyaryl ether ketone can be introduced into the reaction in all suitable forms.
- the polyether ether ketone is preferably used as a powder. If step (i) is carried out in one or more solvents, the polyaryl ether ketone can be dissolved or suspended in at least one alkanesulfonic acid before the reaction with the at least one alkanesulfonic acid and reacted with the at least one alkanesulfonic acid.
- the reaction according to (i) is preferably carried out at temperatures in the range from 15 to 120 ° C., particularly preferably 15 to 90 ° C., more preferably in the range from 25 to 70 ° C. and very particularly preferably in the range from 30 to 50 ° C. , Basically, it is conceivable to keep the temperature constant during the course of the reaction or to change it continuously or in discrete steps. The temperature is preferably kept constant in the course of the reaction.
- the reaction according to (i) is preferably carried out in a period in the range from 1 to 25 h, more preferably in the range from 2 to 20 h and particularly preferably in a period from 4 to 16 h. Accordingly, the present invention also relates to a process as described above, which is characterized in that the reaction according to (i) at temperatures in the range from 15 to 120 ° C., preferably from 15 to 90 ° C. in a period of from 2 to 20 hours is carried out.
- the reaction according to (i) will preferably be carried out under atmospheric pressure. In principle, it is also conceivable to set a pressure other than atmospheric pressure during the reaction. During the reaction, the pressure can be kept constant or change continuously or discretely.
- the molar ratio of the reactants according to (i) is essentially arbitrary.
- a molar ratio of polyaryl ether ketone to alkanesulfonic acid to be sulfonated is in the range from generally 1: 1 to 1: 1000, preferably from 1: 2 to 1: 500 and particularly preferably from 1:10 to 1: 300 chosen.
- the at least one alkanesulfonic acid is used in excess.
- alkanesulfonic acid is used simultaneously as a solvent, it is in a molar excess in relation to the polyaryl ether ketone.
- the reaction in step (i) is carried out in such a way that the alkanesulfonic acid, which is preferably used simultaneously as the solvent, is mixed with the polyaryl ether ketone in a reactor with stirring.
