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 noncoordinatin...

Hexamethylenetetramine-bromine on wet alumina rapidly regenerates carbonyl compounds from their corresponding semicarbazone using microwave under solventless system.

The administration of methenamine mandelate (Mandelamine) to pregnant women causes the levels of estriol in their urines to be unmeasurably low when acid hydrolysis is used. When enzyme hydrolysis replaces acid hydrolysis, normal estriol values are obtained. This result is attributed to the formaldehyde released by acid from hexamethylenetetramine, a constituent of the drug. The formaldehyde re...
