Abstract:
1. A method of reducing at least one of the water content or the acid content in a non-aqueous electrolytic solution for a secondary battery comprising: contacting the non-aqueous electrolytic solution with a triazine compound, wherein the triazine compound is selected from the group consisting of a. 2,6-bis-(2,4-dimethylphenyl)-4-(2-hydroxy-4-octyloxyphenyl)-s-triazine; b. 2,6-bis(2,4-dimethylphenyl)-4-(2,4-dihydroxyphenyl)-s-triazine; c. 2,4-bis(2,4-dihydroxyphenyl)-6-(4-chlorophenyl)-s-triazine; d. 2,4-bis(2-hydroxy(2-hydroxyethoxy)phenyl)-6-(4-chlorophenyl)-s-triazine; e. 2,4-bis(2-hydroxy-4-(2-hydroxyethoxy)phenyl)-phenyl-s-triazine; f. 2,4-bis(2-hydroxy-4-(2-hydroxyethoxy)-phenyl)-6-(2,4-dimethylphenyl)-s-triazine; g. 2,4-bis(2-hydroxy(2-hydroxyethoxy)phenyl)-6-(4-bromophenyl)-s-triazine; h. 2,4-bis(2-hydroxy-4-(2-acetoryethoxy)phenyl)-6-(4-chlorophenyl)-s-triazine; i. 2,4-bis(2,4-dihydroxyphenyl)-6-(2,4-dimethylphenyl)-1-s-triazine; j. 2,4,6-trimethoxy-1,3,5-triazine; k. 2,4,6-triphenyoxy-1,3,5-triazine; l. 2,4,6-triethoxy-1,3,5-triazine; m. 2,4,6-tripropoxy-1,3,5-triazine; n. 2,4,6-tributoxy-1,3,5-triazine, and combinations thereof; wherein upon contacting the non-aqueous electrolytic solution with a triazine compound, an insoluble portion of the triazine compound exists, the method further comprising removing the insoluble portion of the triazine compound.
