^aEmim⁺, Etpy⁺, PrPy⁺, N(C₄H₈)₂⁺, SEt₃⁺, and NEt₄⁺ are 1-ethyl-3-methyl-imidazolium, 1-ethylpyridinium, 1-propylpyridinium, 5-azaspiro[4.4]nonan-5-ium, triethylsulfo-nium, and tetraethylammonium, respectively. x represents the molar fraction of CsHSO₄ in the binary system. Note that the T_liquidus of some systems is not reported.
