Reaction tower for potassium methoxide production

Abstract

A disclosed reaction tower for potassium methoxide production comprises a reaction tower body and a methanol evaporation assembly, the reaction tower body is internally provided with a first cavity and a second cavity, the first cavity is internally and rotatably connected with a plurality of rotating discs, each rotating disc is provided with a reaction tank, the reaction tank is provided with a convex block and a plurality of stirring blocks, and the convex block is provided with a plurality of stirring blocks; the plurality of stirring blocks are arranged at intervals around the axis direction of the rotating disc, the first end of each stirring block is provided with a gas inlet communicated with the first cavity, the second end of each stirring block is provided with a gas channel for methanol steam to enter the reaction tank, and a driving device and an alkali dissolving assembly are arranged in the second cavity; the alkali dissolving assembly conveys a strong alkali solution into the reaction tank, the driving device drives the rotating disc to rotate, so that the strong alkali solution in the reaction tank reacts with methanol steam and is stirred, the reaction is more sufficient, and the production rate and the product quality of potassium methoxide can be improved.

Description

Technical field [0001] The present invention relates to a reaction column for methoxide production. Background technique [0002] Potassium methanol is a methanol product that has a wide range of applications in the chemical industry. At present, there are mainly two ways to produce liquid methanol products: one is "metal potassium method", that is, metal potassium and methanol to form potassium potassium potassium; another method is "base method", i.e., methanol and hydrogen The potassium oxide reaction to produce potassium methoxide, and its advantage is that the price of raw materials is lower than the "metal potassium method", and the process is simple. The use of anhydrous methanol and a strong base during the production process are synthesized, and the chemical reaction formula is as follows: CH3OH + KOH → CH3ok + H2O, in practice, this reaction is reversible, requiring constant production of water steam The reaction system is discharged, so it is necessary to suspend produ...

AI Technical Summary

Problems solved by technology

In the production process, it is necessary to use anhydrous methanol and strong alkali as raw materials for synthesis. The chemical reaction formula is as follows: CH3OH+KOH→CH3OK+H2O. In actual production, this reaction is reversible, and the generated water vapor needs to be continuously transferred from It is discharged from the reaction system, so it is necessary to suspend production every once in a while, and pump out the water generated in the reaction tower, and add anhydrous methanol to the reaction tower as the reaction raw material. In this process, the production efficiency will be greatly reduced. The cost of production has been improved. When the anhydrous methanol vapor and strong base contact in the reaction tower in the prior art, there are a large number of reaction areas in the reaction tower for the contact of anhydrous methanol vapor and strong base, which not only wastes the reaction tower The use space of the body also reduces the efficiency of the reaction tower to produce potassium methoxide. At the same time, the quality of the potassium methoxide generated is impure, and the resulting product will have many impurities.
