Description
Technical Field
The utility model relates to a device for getting rid of metal ion in isopropyl alcohol aqueous solution to the required catalyst of protection esterification reaction belongs to metal ion and gets rid of technical field in the aqueous solution.
Background
Isopropyl acetate is an important organic solvent and has various applications, but in the process of being recycled as an extracting agent, the isopropyl acetate is decomposed into acetic acid and isopropanol under acidic conditions, and the content of the isopropyl acetate is reduced along with the decomposition, so that the normal operation of the extraction process is influenced.
The isopropanol may be distilled and extracted in an isopropanol column to yield an aqueous isopropanol solution having a concentration of about 20%. Under the action of a specific catalyst, the isopropanol water solution and acetic acid generate isopropyl acetate through a chemical reaction, and the generated isopropyl acetate enters the extractant system again. The method obviously reduces the amount of supplementing isopropyl acetate, realizes the recycling of the isopropanol and greatly reduces the production cost. However, the presence of metal cations such as calcium, magnesium, and iron in the aqueous isopropanol solution can cause catalyst poisoning and affect the normal progress of the esterification reaction.
At present, the treatment technology of heavy metal ions in water is mainly divided into four main categories: the physical chemical method, the adsorption method, the microbiological method and the membrane separation technique can select proper treatment techniques according to different concentrations, different types, different sources and different forms of the heavy metal ions. However, these methods are not directly suitable for removing metal cations in an aqueous isopropanol solution, and cannot ensure simple, rapid and effective removal.
Disclosure of Invention
The utility model discloses to the not enough of metal cation in the current isopropanol aqueous solution gets rid of the technique existence, provide a simple structure, effectively get rid of metal cation's in the isopropanol aqueous solution reliably filter.
The utility model discloses a metal ion gets rid of filter in isopropyl alcohol aqueous solution adopts following technical scheme:
this filter, including a jar body, jar body upper portion is provided with the inlet pipe, and the bottom is provided with the leakage fluid dram, and jar internal upper portion is provided with material distributor, and material distributor below is provided with the cation exchange resin layer, and the distribution of cation exchange resin layer below has the drain cap, and the inlet pipe is connected with material distributor.
