Technical field
The invention belongs to organosilicon material field, be specifically related to a kind of organic silicon defoamer being applicable to Hydrogen Peroxide Production
Preparation method.
Background technology
At present, the technique more maturation producing hydrogen peroxide both at home and abroad is anthraquinone.Process for prepairng hydrogen peroxide by anthraquinone is main
Experience hydrogenation and two stages of oxidation.Hydrogenation stage: be dissolved in compounded organic solvent by alkyl-anthraquinone, in uniform temperature and pressure
Being passed through hydrogen under the conditions of power, hydrogenating alkyl anthraquinone generates hydrogen anthraquinone.Oxidation stage: the organic mixed solvent containing hydrogen anthraquinone is led to
Enter oxygen, the oxidized alkyl-anthraquinone that generates once again of hydrogen anthraquinone, generate hydrogen peroxide simultaneously.
Production process needs be passed through hydrogen and oxygen, in being passed through gas process, foam can be produced, occupy certain appearance
Long-pending, affect utilization rate of equipment and installations.Meanwhile, this working solution can not add aqueous or using water as the defoamer of solvent, because water meeting
On catalyst activity position, there is competitive Adsorption with anthraquinone, reduce the active constituent absorbability to anthraquinone, thus reduce catalysis
The activity of agent.At present, the defoamer for Hydrogen Peroxide Production does not the most also occur.
