[0003] In the prior art, the patent with the authorized announcement number CN201821572562.3 discloses a purification system for the working fluid in the production of hydrogen peroxide, including a flash tank, a primary vacuum condenser, a secondary vacuum condenser, a water separator, and a pumping system. Vacuum system, the feed port of the flash tank is set in the middle of the top of the tank, the feed port is connected to the middle of the distributor through an inverted bell-mouth diffuser tube, and a wire mesh packing layer is arranged on the distributor , there is a second distributor under the distributor. The existing ultra-high-purity hydrogen peroxide manufacturing process has certain disadvantages in use. First, it cannot be prepared conveniently and quickly during use, and the preparation process is more troublesome. , is not conducive to people's use, and also, the hydrogen peroxide cannot be purified well, and the purity is low, which brings certain adverse effects to people's use process. Therefore, we propose a production of ultra-high-purity hydrogen peroxide craft

Abstract

The invention discloses a manufacturing process of ultra-pure hydrogen peroxide. The manufacturing process comprises the following operation steps: weighing ultra-pure aluminum oxide, grinding and crushing the ultra-pure aluminum oxide to obtain aluminum oxide powder, cleaning the aluminum oxide powder multiple times by using ultrapure water, conducting heating, keeping aluminum oxide in a powder state, mixing the aluminum oxide powder with the ultrapure water, conducting stirring until sticky paste is obtained, performing shaping, performing high-temperature drying operation to form a filtering mechanism, stirring a certain amount of a hydrogen peroxide raw material at a high speed in an ultrasonic vibration manner, and slowly introducing the stirred hydrogen peroxide raw material into the filtering mechanism for processing ultra-pure aluminum oxide for filtering operation. According to the manufacturing process of the ultra-pure hydrogen peroxide, the purity of the hydrogen peroxide is increased through distillation and concentration methods, an adsorption type purification membrane material is added into the hydrogen peroxide for reaction, the effects of adsorption filtration and water removal are achieved, purity is further improved, and the ultra-pure hydrogen peroxide is better prepared.
