Continuous preparation method of ultra-clean high-purity hydrogen peroxide

Abstract

The invention discloses a continuous preparation method of ultra-clean high-purity hydrogen peroxide, which comprises the following operation steps: selecting a certain amount of industrial-grade hydrogen peroxide, a certain amount of styrene monomer, a certain amount of divinylbenzene monomer, a certain amount of toluene organic solvent and a certain amount of filler; preparing the styrene monomer, the divinylbenzene monomer, the toluene organic solvent and the filler into a porous resin adsorption material body through a suspension copolymerization method,enabling industrial-grade hydrogen peroxide to sequentially pass through the porous resin adsorption material body, a cation exchange column and an anion exchange column at the flow speed of 280-460 L / H and then filtering circularly by a 0.1-micron filter element, and obtaining primarily purified hydrogen peroxide. According to the continuous preparation method of the ultra-clean high-purity hydrogen peroxide, feeding operation can be carried out in a pumping mode, the feeding amount is convenient to control, continuous preparation operation can be carried out, the preparation efficiency is improved, constant-temperature evaporation purification treatment is carried out under the low-temperature condition, the purity of hydrogen dioxide is improved, and the using effect is more excellent.

Problems solved by technology

[0003] In the prior art, the patent with the authorized announcement number CN201811216055.0 discloses an electrochemical device and application for preparing hydrogen peroxide. The device consists of a cathode chamber, an anode chamber, a cathode and an anode; the side of the cathode chamber and the side of the anode chamber The bottom of the cathode chamber is provided with a gas distribution chamber under the cathode, and the top surface of the gas distribution chamber is a porous plate; the bottom surface of the cathode is set toward the midline of the top surface of the gas distribution chamber; Miscellaneous foam carbon, the existing continuous preparation method of ultra-clean high-purity hydrogen peroxide has certain disadvantages in use. First of all, when it is used, the preparation is relatively troublesome, and the continuous preparation cannot be carried out well, and the preparation efficiency Poor, not conducive to people's use, in addition, in the process of preparation, the purification process cannot be carried out well, the purity is reduced, and the use effect is poor, which brings certain adverse effects to people's use process. For this reason, We propose a continuous preparation method for ultra-clean and high-purity hydrogen peroxide
