1 g of TAIC and 20 g of water obtained in the above examples were placed in a Teflon (registered trademark) pressure vessel, heated at 120 ° C. for 200 hours, and then the chloride ion concentration in water was measured. The chloride ion concentration was measured by an iona chromatograph (column used: “DIONEX Ion Pack AS12A”, eluent: 2.7 mM Na 2 CO 3 /0.3 mM NaHCO 3 ). The detection limit is 1 ppm. The results are shown in Table 3.
