Manufacturing process of ultra-pure hydrogen peroxide

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.

Description

technical field [0001] The invention relates to the field of hydrogen peroxide preparation, in particular to a manufacturing process of ultra-high-purity hydrogen peroxide. Background technique [0002] The manufacturing process of ultra-high-purity hydrogen peroxide is a method for the preparation and purification of hydrogen peroxide. The hydrogen peroxide becomes hydrogen peroxide, which is a colorless transparent liquid and is a strong oxidant. Its aqueous solution is suitable for medical wound disinfection, environmental disinfection and food disinfection. , Widely used in chemical, military and medical fields, with the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of ultra-high purity hydrogen peroxide.

Problems solved by technology

[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
