Method for realizing and controlling electrolyte metathesis reaction

Abstract

The invention discloses a method for realizing and controlling an electrolyte metathesis reaction. The method for realizing and controlling an electrolyte metathesis reaction is a universal metathesis method relating to a chemical electrolyte metathesis technology. The method for realizing and controlling an electrolyte metathesis reaction is a novel method capable of a realizing metathesis reaction between water-soluble ionizable electrolyte compounds. The method for realizing and controlling an electrolyte metathesis reaction is characterized in that anions and cations of all reactant electrolyte solutions undergoing a metathesis reaction are separated and the separated anions and cations are interchanged and then are recombined. In an electric energy utilization respect, the method for realizing and controlling an electrolyte metathesis reaction is characterized in that a direct current and an alternating current are not needed in metathesis reaction initiation but electric energy is needed in solution suction. The method for realizing and controlling an electrolyte metathesis reaction simplifies production processes of a few of acids, alkalis and salts, saves electric energy, and realizes metathesis preparation of many acids, alkalis and salts, wherein the many acids, alkalis and salts cannot prepared by the existing metathesis method. For example, through method for realizing and controlling an electrolyte metathesis reaction, raw materials of gypsum, salt and water can be prepared into sulfuric acid, caustic soda, hydrochloric acid and sodium sulfate through metathesis reactions; and salt and water are prepared into caustic soda and hydrochloric acid through a metathesis reaction.

Description

1. Technical field [0001] The invention relates to the field of chemistry and the metathesis technology of electrolytes. 2. Background technology [0002] In chemistry, the reaction in which two electrolytes exchange ions with each other to form two new electrolytes is called a metathesis reaction; the reactions between acids, bases, and salts are generally metathesis reactions. If the electrolyte compounds can be converted into each other and produced from each other through the method of metathesis, then in the chemical industry, the manufacturing process of many chemical raw materials will be much simpler. However, the existing chemical technology cannot make metathesis reaction between any acid, alkali and salt. The conditions for the metathesis reaction to occur are very harsh, and the conditions are: there must be precipitation, gas release or water generation in the product, otherwise the metathesis reaction cannot proceed. [0003] In the chemical industry, because...

Problems solved by technology

Therefore, the metathesis reaction in the prior art is restricted by the physical and chemical properties of the product, so many acids, alkalis, salts and other electrolytes cannot carry out the metathesis reaction.
