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 EOnPOmEOn at a rate higher than 90% to obtain high-quality mesoporous alumina.
