Reflux condenser pipe special for microwave chemistry

Abstract

The invention discloses a reflux condenser pipe special for microwave chemistry, which mainly comprises an external layer water sleeve (3), a standard ground (4), a barrel-shaped pipe (5), baffle stabs (6), an inner core pipe (7), a coil pipe (8), a water distribution head (10) and a serial ball pipe (11). The reflux condenser pipe special for the microwave chemistry is characterized in that: the standard ground (4) at the upper end of the external layer water sleeve (3) is welded with the barrel-shaped pipe (5) together; the baffle stabs (6) are uniformly distributed at the periphery of the inner wall of the barrel-shaped pipe (5); the lower end of the barrel-shaped pipe (5) is welded with the upper end of the serial ball pipe (11); the lower end of the inner core pipe (7) is connected with the water distribution head (10); and the coil pipe (8) is coiled outside the inner core pipe (7), and the lower end of the coil pipe (8) is connected with the water distribution head (10). Therefore, blasting explosion and high consumption of an organic solvent can be effectively prevented.

Description

technical field [0001] The invention belongs to a special reflux condensation tube for microwave chemistry, which is applied in microwave radiation heating technology of organic synthesis, metal organic, macromolecule, material chemistry and inorganic synthesis, and can effectively prevent organic solvent explosion and large dissipation. Background technique [0002] The use of microwave radiation technology in synthetic chemistry began in 1986. R.Gedye et al. used microwave ovens for esterification, hydrolysis, oxidation and nucleophilic substitution reactions and R.J.Giguere et al. for the Diels-Alder cycloaddition of anthracene and dimethyl maleate Response research. Since then, microwave heating technology has been widely used in organic synthesis, metal-organic, polymer, material chemistry, and inorganic synthesis. The application in the field of chemistry and the research on the reaction mechanism rarely focus on the research on the structure of microwave reactors. So...

AI Technical Summary

Problems solved by technology

However, in the microwave radiation heating process, because the microwave heating rate is too fast, the evaporation cannot diffuse the excess energy in time, and it is very easy to cause liquid explosion and organic solvent to be dissipated into the room, which directly damages the health of the experimenters.
