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

Resumo

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 T_g = –32.3°C.
