Barium hydroxy ethoxylate: A new green and highly soluble barium compound

Abstract

In this study, barium hydroxy ethoxylate (Ba(OH)(OEt)) was synthesized for the first time as a new barium compound by dissolving barium oxide into ethanol (EtOH). The results, in contrast to the previous studies, reveal that the dissolving process is actually a chemical reaction of barium oxide and ethanol rather than a simple solvation, and barium hydroxy ethoxylate is uniformly dispersed among ethanol molecules without any solvation or coordination. Furthermore, barium hydroxy ethoxylate is highly soluble (29.79%) and its solvent ethanol is friendly to people and environment, which makes it a promising barium precursor in many applications.
