Solid phase synthesis method by gas stream to increase efficiency and continuous microwave radiation, and apparatus therefor

Abstract

The invention is solidoid composition reaction of airflow potentiating continuous microwave radiation and the equipment. It relates to microwave radiation solidoid composition technology field. The method is: in the microwave energy field, the reacting materials are radiated continuously by the microwave on the deferent strip, the jet vertical airflow potentiates through deferent web to solidoid compose the reacting materials. The equipment comprises a reacting chamber with a plurality of microwave resources, a deferent strip carrying the reacting material and moving horizontally, the airflow deferent strip web in the reacting chamber to implement vertical potentiating and continuous microwave radiation soldoid composition reaction, the exhausting mouth recycling the gas. The equipment can make the microwave radiate the materials evenly, prevents the coking reaction caused by side-product strong acid and partial heat accumulation, lowers the cost, increases the reaction speed and improves the purity of products and composition efficiency of microwave.

Description

technical field [0001] A gas flow synergistic continuous microwave radiation solid-phase synthesis reaction method and device relate to the technical field of gas flow-carrying synergistic microwave radiation solid-phase synthesis in a microwave energy field. Background technique [0002] The heating of matter by microwaves starts from the molecules of the matter, which is called "internal heating". Matter in nature is composed of a large number of dipoles that are positively charged at one end and negatively charged at the other end. In the natural state, the dipoles move and arrange chaotically. When the medium is in the electric field, the randomly oriented dipoles will have the same orientation according to the direction of the electric field. When the direction of the electric field changes hundreds of millions of times per second, the orientation arrangement of the dipoles in the electric field will also change rapidly, resulting in intermolecular Collide with each ot...

Problems solved by technology

Microwave heating Because the microwave energy is directly converted inside the heated system, if the heat accumulated in the heated system cannot be effectively released, microwave heating will easily lead to temperature out of control, and the overheating phenomenon of "high temperature coking point" will appear

[0004] The existing large-scale industrial microwave processing equipment generally adopts a continuous transfer box-type microwave chemical reactor, which has a large processing capacity, but it is a non-closed system, which is only suitable for static physical heating of materials, and the continuous "internal heating" effect can make the reaction system The internal heat accumulates to form a high-temperature coking point, causing the temperature to lose control instantaneously. In addition, the free hydrochloric acid radicals will also cause the reactants and products to melt or even burn.
