文摘
The aim of this work was the optimization of the neutralization process to remove the catalyst from a polyether polyol. Some parameters were studied: water content, dehydration curve conditions, the acid concentration of the neutralization solution, and temperature. The final cesium content was kept under the specified value. However, the final value of polyol acidity was higher than that of the commercial specification for these kinds of polyol.
