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.

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...

background: possibility to trace-label albumin with isotopes results in information concerning its synthesis, breakdown, and distribution in the intra and extra cellular spaces. the iodination of albumin is a widespread procedure used in scientific studies. bromine not only is more reactive and less expensive than iodine, but bonds more easily with many elements. therefore, it could be a suitab...

a study was undertaken to investigate the role of placenta in transferring drugs containing bromine to the infant. 20 pregnant subjects were given bromine as kbr (500 mg/50 kg weight) 10h before the delivery the bromine content of the serum in the mother and the child was estimated by neutron.. 13 lrradlated at 2xlo activation analysis. samples were -2 -1 n em 5 for a period of one hour. a ge (...

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...

A spectrophotometric study concerning the interactoin between iodine and bromine with tetrabutylammonium iodide (TBAI), tetrabutyl- ammonium bromide (TBABr) and cryptand 222 (C222) has been performed in dichloromethane solution at 25°C. The results are indicative of the formation of TBA+X3- and  C222X+X3-  t...

Bromine is one of the most abundant and ubiquitous trace elements in the biosphere and until recently had not been shown to perform any essential biological function in animals. A recent study demonstrated that bromine is required as a cofactor for peroxidasin-catalysed formation of sulfilimine crosslinks in Drosophila. In addition, bromine dietary deficiency is lethal in Drosophila, whereas br...
