The first metal-organic framework containing an unprecedented in situ-generated C-substituted hexamethylenetetramine ligand has been successfully prepared by the reaction of silver nitrate, 4-formylbenzoic acid and hexamethylenetetramine under traditional solution conditions, which holds the unusual (3,4)-connected topological network.

What is the difference between argentaffin and argyrophilic reactions? Both terms relate to the formation of colloidal metallic silver (latin argentum, Greek argyros) (1), which may range in color from yellow through brown to black depending on particle size and density, in specific structural components of tissues. the metal is formed at sites of reduction of silver ions derived from a stainin...

introduction: currently, developing new antibacterial drugs as alternative antibiotics is a very active area of research, due to widspreading widespread prevalence of resistant strains of microorganisms. this work intends to investigate of antibacterial properties and influence on immune blood cells of the silver-based compound hexamethylenetetramine (methenamine) silver nitrate with general fo...

Divalent metal (Mn, Co, Ni) complexes of the ligand hexamethylenetetramine (HMTA, C6H12N4) with sulfate, nitrate and fluoroborate as counter ions have been synthesized in ethanolic media. Whereas the complexes with BF4 and NO3 as counter ions have two molecules of hexamethylenetetramine, those with SO4 2as counter ion contain just one molecule of hexamethylenetetramine. The complexes have been ...

The extension of the study of the quaternary salts of hexamethylenetetramine to those obtained by the addition of this base to the most varied types of substances containing aliphatically bound halogen has demonstrated that the introduction of the hexamethylenetetramine nucleus in this manner results in the production of bactericidal substances or enhances the bactericidal action if already pre...

mono and bis hexamethylenetetramine iron(iii) chloride, fe(n c ,h ) ci (i) and fe(n c ,h ) cl (ii) were synthesized by the reaction of iron(iii) chloride and hexamethylenetetramine (hmta) in chloroform. chemical analysis and spectral results show the coordination of hmta to the iron(iii). electronic transition spectra of compound i and i1 were also studied in coordinating and noncoordinating so...

In 1916 Jacobs, Heidelberger, and coworkers at the Rockefeller Institute reported the discovery of a new class of synthetic compounds which possessed potent bactelicidal properties. By reacting hexamethylenetetramine with a large variety of substituted benzylor alkyl-halides, nujmerous quaternary salts of this base were obtained. It was observed that most of these salts had pronounced bacterici...

This paper deals with a standard classification procedure for readily combustible solids and their assignment to the relevant packing groups according to international air-cargo legislation and regulations. The current International Air Transport Association and United Nations Orange Book regulations were used on chemically similar substances: hexamethylenetetramine and Dancook ignition briquet...
