An ammonium salt having a saccharin anion, which is represented by formula (1), exhibits excellent thermal stability even though no halogen atom is contained therein.
(In the formula, each of R1-R4 independently represents an alkyl group having 1-4 carbon atoms or an alkoxyalkyl group that is represented by -(CH2)n-OR (wherein R represents an alkyl group having 1-4 carbon atoms, and n represents an integer of 1 or 2). Incidentally, any two of the R1-R4 may combine with each other to form a ring together with a nitrogen atom.)
由式(1)表示的具有
糖精阴离子的
铵盐,即使不含卤素原子,也具有极佳的热稳定性。
(式中,R1-R4 各自独立地代表具有 1-4 个碳原子的烷基或由 -(
CH2)n-OR 表示的烷氧基(其中 R 代表具有 1-4 个碳原子的烷基,n 代表 1 或 2 的整数)。顺便提一下,R1-R4 中的任意两个可以相互结合,与一个氮原子一起形成一个环)。
