Neutralization-mediated extraction of amphiphilic organic molecules for obtaining high-quality mesoporous alumina

Abstract

A solvent extraction method was improved using organic bases such as triethylamine (Et₃N) that neutralize HCl effectively and stabilize sol–gel derivative alumina frameworks as insoluble species, thereby achieving removal of EO_nPO_mEO_n at a rate higher than 90% to obtain high-quality mesoporous alumina.
