title = "Determination of green solvents{\textquoteright} water activity by inference of freezing point depression",
abstract = "Deep eutectic solvents (DESs) are novel green solvents with great potential in many industrial applications. Due to their high tunability, DESs can be synthesized and prepared into various concentrations by dilution with water. This work revolutionises the determination of selected DESs{\textquoteright} water activity using inferencing their respective freezing point depression. Using the Hildebrand-Scott equation, the freezing point depression of the respective DESs in various concentrations is then correlated to the water activity. This inferential correlation provides an alternate but convenient way of determining a solution{\textquoteright}s water activity in absence of a water activity meter. The highest freezing point depression of almost -10 oC was observed on the choline chloride and ethylene glycol in 1:2 molar ratio DES at 50 wt% concentration, with corresponding water activity determined at 0.909.",
