PROBLEM TO BE SOLVED: To provide an antifreezing agent which has an excellent anticorrosion property, can be produced easily, and is inexpensive.SOLUTION: An antifreezing agent comprises a chloride and disodium hydrogenphosphate (NaHPOxHO (x=0 to 12)), wherein the chloride is sodium chloride (NaCl). As the chloride, natural salt may be used. Also, in place of sodium chloride (NaCl), there may be used calcium chloride (CaCl), or sodium chloride (NaCl) and calcium chloride (CaCl). In a case of a granular antifreezing agent, disodium hydrogenphosphate is preferably anhydride. Furthermore, in place of disodium hydrogenphosphate, dipotassium hydrogenphosphate may be used. |
