Temperature and density effects on structural features of a dilute aqueous lithium chloride solution at near- and supercritical conditions

► We study the structural features of near- and supercritical LiCl(aq) solutions. ► We analyze the temperature or/and fluid density effects on the structure of LiCl(aq). ► Temperature growth and density decrease have similar effect on the H-bonds decrease. ► We found the same effect with regard to thermal ion dehydration. ► Ion association is mainly affected by rising temperature.
