Method and device for synthesizing compound by solid phase reaction

Abstract

The invention relates to a method for synthesizing a compound by solid phase reaction, which comprises the following steps that: 1, solid reactants are mixed and are accelerated to reach supersonic speed by high-speed carrier airflow, so that the solid reactants have high kinetic energy; 2, a microwave field is arranged in the motion process of the solid reactants, so that the solid reactants pass through the microwave field to enhance the molecular thermal motion of the reactants and improve activity; and 3, the solid reactants are synthesized, namely A, the solid reactants which moves at a high speed impact a fixed target circularly, and are crushed gradually to form solid reactants with molecular grain diameters; and B, the solid reactants with the molecular grain diameters impact a target head at the high speed, so that the kinetic energy is converted into internal energy, molecular chemical bonds are broken to be decomposed into ions, and negative ions and positive ions recombineto form bonds to synthesize the target compound. By the method, the high-temperature limit of the conventional solid phase reaction is broken through, so that the solid phase reaction can be performed at normal temperature. Therefore, a new technical route is provided for the synthesis of the compound, the application range is wide, the reaction speed and yield are high, cost is low, and obvious economic and environment-friendly effects are achieved.

Description

technical field [0001] The invention relates to a method for synthesizing compounds, in particular to a method for synthesizing compounds by solid-phase reaction and a device thereof. Background technique [0002] At present, environmental pollution and excessive energy consumption are causing more and more harm to the earth and human beings. While developing the economy, people are also actively facing how to overcome environmental pollution and protect our ecological balance. In the past ten years, due to the fact that the traditional chemical reaction is carried out in solution or gas phase, the reaction requires high energy consumption, long time, serious environmental pollution and complex process, so more and more people are turning their attention to Utilized solid-phase chemical reactions. Solid phase reactions are those reactions involving solid substances. That is to say, the reactant must be a reaction of solid matter to be called a solid state reaction. Solid...

Problems solved by technology

[0003] But for a long time, because the traditional solid-state reaction materials mainly involve some inorganic solids with high melting point, such as silicates, oxides, metal alloys, etc., these materials generally have the characteristics of three-dimensional network structure, small atomic gap and strong chemical bond. , the solid-phase synthesis reaction is mostly carried out at high temperature. First, the reaction material is calcined, and then ground by a ball mill to make it react. The disadvantages of this method are: 1. High-temperature calcination consumes a lot of energy; 2. The physical process of ball milling is long, High cost; 3. Impurities brought by grinding ball wear, resulting in low product purity; 4. Narrow application range, limited to high melting point inorganic solids, and cannot be used for low melting point inorganic substances, especially organic substances
