Abstract
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.)
Claims6
An ammonium salt having a saccharin anion, represented by the formula (1):
- wherein R1 to R4 are each independently an alkyl group having 1 to 4 carbon atoms or an alkoxyalkyl group of —(CH2)n—OR wherein R is an alkyl group having 1 to 4 carbon atoms and n is an integer of 1 or 2, provided that any two of the R1 to R4 may combine with each other to form a ring together with a nitrogen atom.
