Description
Technical field
The present invention relates to hydrogen peroxide preparation technologies, and in particular to a kind of add-on system and technique of stabilizer.
Background technique
Hydrogen peroxide also known as hydrogen peroxide, molecular formula are H2O2.That is, a hydrogen peroxide molecule contains, there are two oxygen atoms.Although
Hydrogen peroxide can resolve into water (H2) and oxygen (O O2), but be not in hydrogen peroxide " containing high-concentration oxygen ".Hydrogen peroxide is public
The low toxicity material recognized is widely used in the fields such as industrial bleaching, surgical sterilizing.
The purposes of hydrogen peroxide point is medical, military and three kinds industrial, and daily disinfection is medical hydrogen peroxide, medical hydrogen peroxide
Pathogenic entero becteria, pyococcus can be killed, pathogenic yeast bacterium is generally used for surface disinfection.There is hydrogen peroxide oxidation to make
With, but medical hydrogen peroxide concentration is equal to or less than 3%, wipes wound face, has burning sensation, surface is oxidized to white and emits
Bubble, with clear water clean can, cross and just restore the original colour of skin in 3~5 minutes.
The industrial making method of hydrogen peroxide has: alkaline hydrogen peroxide preparation method, phosphoric acid neutralisation, electrolysis sulfuric acid process and 2- ethyl hydrazine
Method.It is 2- ethyl hydrazine (EAQ) method that industrial scale, which produces main method,.2- ethyl hydrazine is in certain temperature and pressure in catalyst
Effect is lower and hydrogen reaction generates 2- ethyl hydrogen anthraquinone, and with oxygen redox occurs for 2- ethyl hydrogen anthraquinone under certain temperature and pressure
Reaction, 2- ethyl hydrogen anthraquinone reduction generate 2- ethyl hydrazine and generate hydrogen peroxide simultaneously, obtain aquae hydrogenii dioxidi using extraction
Solution finally purifies to obtain qualified aqueous hydrogen peroxide solution by heavy aromatics, is commonly called as hydrogen peroxide, this technique is used to prepare mostly
27.5% hydrogen peroxide, can be by distilling if the higher aqueous hydrogen peroxide solution of concentration (hydrogen peroxide such as 35%, 50%)
It arrives.
Due to dioxygen water unstable, it is readily decomposed to oxygen and water, thus is often needed in industrially prepared hydrogen peroxide process
Stabilizer is added into hydrogen peroxide storage tank, so that the decomposition rate of hydrogen peroxide is effectively reduced, when the hydrogen peroxide of preparation being made to meet long
Between storage and for a long time transport.
However, the hydrogen peroxide stabilizer Adding Way of system is that irregularly interval is poured into surely with container at the top of hydrogen peroxide storage tank
Determine agent, this stabilizer adding manner has the following deficiencies: first is that stabilizer and hydrogen peroxide cannot be mixed uniformly, and stabilizer is effective
The stabilizer that acting on cannot discharge completely, while not spread sufficiently also will affect the analysis result and using effect of hydrogen peroxide.
