The influence of the addition of NaCl on the temperature‐induced phase separation of 3‐methoxypropionitrile and water was investigated experimentally and theoretically. Experiments performed under direct microscopic observation revealed an enhanced domain growth speed and an improved clarifying behavior. It was found that the relevant physical properties changed dramatically with the addition of NaCl, which induced a shift of the equilibrium curve and a change of the operational temperature. Dissipative particle dynamics simulations have also predicted this shift, although electrostatic interactions were not taken into account explicitly in the current study.
