Definitions
- the application relates to a method for conditioning ion exchange resins, the ion exchange resin mixtures conditioned in this way and their
- Used ion exchange resins based on crosslinked polystyrene are generally disposed of by burning a suspension of the ion exchange beads in a solvent. So far, water has been used as the suspension liquid. This type of disposal is technically and energetically complex, since large volumes have to be transported and water has to be evaporated.
- An alternative disposal method is the dissolving in oxidizing solutions of Fe (II) / Fe (III) in hydrogen peroxide: JP-A-58 161 898, JP-A-57 001 446, DE-A-3 926 252, this is technically complex The process is described for radioactive ion exchange materials, the thermal disposal of which causes problems.
- the task was therefore to convert the ion exchange resins to be disposed of into an easy-to-use form that can be easily disposed of.
- the invention therefore relates to a process for conditioning ion exchange resins, in particular ion exchange resins based on crosslinked polystyrenes, in particular those which are used as a catalyst in processes for the preparation of bisphenols, characterized in that the ion exchange resins are mixed with at least one organic liquid in which the resins have a smaller volume than water.
- Such liquids are preferably aprotic solvents and solvent mixtures such as, for example, and preferably aromatic and aliphatic ketones, such as, in particular, acetone and MIBK, aromatic and aliphatic hydrocarbons, such as, in particular, hexane, heptane, diesel oils, light oil fractions, heating oils, waste oils and / or ethers.
- Light fuel oils, diesel oils and waste oils as well as liquid residues from distillation plants are preferred which are produced during the production or processing of the above-mentioned organic liquids.
- the amount of liquids added to the ion exchange resins can easily be determined by preliminary tests. It will preferably be
- Amounts used that the solids content in the mixture of ion exchange resin / liquid, which is generally in suspension, is 40 to 85% by volume, preferably 55 to 65% by volume.
- Mixing ratios of 1 to 2, in particular 1.3 to 1.5 parts by weight of resin to 2 to 0.5, in particular 1.5 to 1, part by volume of liquid are preferred.
- the ion exchange resin-liquid mixture can be prepared by simply stirring the components.
- the mixture is easily pumpable.
- a larger amount of resin in the same volume can be transported and disposed of in the mixture with the solids content remaining the same as in the known water suspensions.
- disposal by incineration of the mixture according to the invention is less expensive.
