Glass Formation in the AlCl3–(CH3)2SO–H2O System

Abstract

Glass formation in the AlCl–(CH3)2SO–H2O system was detected for the first time, the boundaries of the glass formation region were determined, and glass AlCl3 · 2.9(CH3)2SO · 4.8H2O was synthesized. The IR spectra of glass-forming solutions within the boundaries of the glass formation region and the glass AlCl3 · 2.9(CH3)2SO · 4.8H2O were recorded. It was concluded that (CH3)2SO enters the first coordination sphere of the aluminum ion through the oxygen atom. The glass AlCl3 · 2.9(CH3)2SO · 4.8H2O was studied by calorimetry, and its glass transition temperature was determined to be Tg = –32.3°C.
