The germicidal activity of some pyridinium salts containing unsaturated hydrocarbon radicals.
The germicidal potency of quatemary ammonium compounds is known to depend mainly on the chemical structure of the cation, the nature of the anion having little if any effect (Glassman, 1948). The relation of structure of the cation to bactericidal activity has been studied extensively insofar as chain length of the hydrophobic or hydrocarbon group is concerned. In compounds with only one long c...
متن کاملSynthesis and antimicrobial activity of some pyridinium salts.
Some substituted benzylidenehydrazinylpyridinium derivatives bearing benzyl, ethylphenyl and propylphenyl groups on the pyridinium nitrogen were synthesized and screened for possible antibacterial and antifungal activities against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Candida albicans using the microdilution method. Antimicrobial test results indicated that compoun...
متن کاملCetyl Pyridinium Chloride : I. Germicidal Properties.
Cetyl pyridinium chloride is a cationic detergent which is soluble in water, chloroform, alcohol, and acetone. Aqueous solutions are clear, colorless, and odorless. The agent has a depressant action upon surface tension. This property enhances the value of the germicide because irregular surfaces are uniformly wetted. The germicidal properties of cetyl pyridinium chloride were first studied in ...
متن کاملThermolysis of pyridinium perchlorate salts
Three perchlorate salts of pyridine have been prepared and characterized by gravimetric and elemental analyses. Thermogravimetry (TG) and differential thermal analysis (DTA) have been carried out in static air, to examine the thermal decomposition process of these salts. Isothermal TG of these salts have been done to evaluate the kinetics of thermal decomposition in the temperature range 290-41...

Die Anlagerung von Nucleophilen an quartäre Pyridinium-Salze ist seit langem bekannt [2], ebenso die Beobachtung, daß Ringöffnungsund Umlagerungsreakt ionen sich anschließen können, gerade bei der Einwirkung von z.B. Hydroxidoder Alkoxid-Ionen und Aminen [3, 4]. Quartäre Salze von Pyridincarbaldoximen, die ausgeprägt hydrophile Eigenschaf ten haben, werden als Reaktivatoren bei In toxika t ion ...
