polyether adsorbent aluminum silicate CAS NO.:12141-46-7
Product description
Refined adsorbent aluminum polysilicate (Synthetic aluminum Poysilicum), molecular formula: xAl2O3·ySiO2·nH2O.
The appearance is a kind of white porous spherical body particle or powder, has the very good flowability, it belongs to the solid acid compound. As a hard foam polyether refined absorbent, it shows excellent adsorption and decolorization performance: adsorption of potassium and sodium ions from organic chemicals. And play a role in filtering. Absorb water from the air.

Product application:
the crude polyether polyol was put into the neutralization kettle, a small amount of pure water was added at a certain temperature, the neutralization reaction was carried out after stirring, the PH value of the neutralization solution was controlled within the index (6.5 - 7.0), then 0.1 - 0.3% aluminum polysilicate adsorbents were added at the same temperature, the vacuum distillation and dehydration were carried out for 1.5~2H,
and the filtration cycle was carried out when the water was removed to the prescribed requirements. The K+ (Na+) ion content of the circulating liquid is analyzed and filtered immediately when it meets the requirements. The filter solution is a clear and transparent polyether.
