Tetraboric acid
[Chinese name] Potassium tetraboric acid; Potassium borate
[English name] Potassium tetraborate; Potassium Borate
[Structure or Molecular Formula] K2B4O7 · 5H2O
[Registration Number] CAS [1332-77-0]
【 Character 】 White crystal.
Soluble in water, the aqueous solution is alkaline and slightly soluble in alcohol.
purpose
It can be used to manufacture disinfectants, as casein solvent and anti-wear additive, as well as a component of welding flux and diazo developing solution. In chemical analysis, the most suitable standard substance used for determining the titration of acids.
Preparation or source
The potassium carbonate neutralization method places the dissolved potassium carbonate solution in a reaction tank and slowly adds boric acid at a certain temperature for reaction. After completion, the solution is filtered to remove water insoluble substances. Then, after cooling, crystallization, centrifugation, and drying, potassium borate products are prepared. Further refinement and purification can yield reagent products.
Security
Packed in polyethylene plastic bottles, with a net weight of 0.5kg per bottle. Alternatively, polyethylene plastic bags can be used internally and woven bags can be used externally, weighing 25kg. It should be stored in a ventilated and dry warehouse. The packaging must be sealed, and care should be taken to prevent damage during transportation and loading/unloading.
