Abstract Deprotonation of the NbH acid 1,8-bis(4-toluenesulphonamido)-2,4,5,7-tetranitronaphthalene by proton sponges 1,2-bis(di-R-aminomethyl)benzene (R Me, Et, Pr, Bu) has been studied by kinetic and spectroscopic methods. Mixtures of the proton sponges with the NH acid in acetonitrile solution give products which are cations and anions with [NH ⋯ N] + and [NH ⋯ N] − homoconjugated intramolecular
A disinfectant comprising at least one quaternary ammonium salt represented by the following general formula (1):
wherein R1 represents an alkyl group of 8-14 carbon atoms, R2 and R3 each represent an alkyl group of 1-2 carbon atoms, and [B] represents two monovalent inorganic or organic anion groups or one divalent inorganic or organic anion group. The disinfectant has excellent bacteriocidal activity and is suitable as a disinfectant for medical care and working areas.
