Product Description

 Urotropine, Hexamine, Solid Fuel Tablet, Cooking Fuel, Smokeless and Tasteless Flammable ...

 

Introduction:

The compound was discovered by Aleksandr Butlerov in 1859. Hexamethylenetetramine is prepared industrially by combining form aldehyde and ammonia.

The reaction can be conducted in gas phase and in solution.

The molecule has a symmetric tetrahedral cage-like structure, similar to adamantane, whose four "corners" are nitrogen atoms and "edges" are methylene bridges.

Although the molecular shape defines a cage, no void space is available at the interior for binding other atoms or molecules, unlike crown ethers or larger cryptand structures.

The molecule behaves like an amine base, undergoing protonation and N-alkylation.Urotropine, Hexamine, Solid Fuel Tablet, Cooking Fuel, Smokeless and Tasteless Flammable.

 

 

Application:

The dominant use of hexamethylenetetramine is in the production of powdery or liquid preparations of phenolic resins and phenolic resin moulding compounds, where it is added as a hardening component.

 

These products are used as binders, e.g. in brake and clutch linings, abrasive products, non-woven textiles, formed parts produced by moulding processes, and fireproof materials.

 

Description:
Hexamine also named Urotropine is a kind of raw material for the curing agent of phenolic plastic, the catalytic agent of amino plastic, the blowing agent h(dpt)of vulcanized rubber, the anti shrinking agent for textile goods, diuretic and germicide of pharmacy, the black explosive of military industry and the pesticide of agriculture. And it can be used for the absorbent for light and air in the poison gas mask, if it is mixed with caustic soda & phenoxide.

Storage precautions: 
Store in cool, ventilated warehouse. Away from fire and heat source. Packing seal. Should be stored apart and oxidant, acid, mixed reservoir of avoid by all means. Use explosion-proof lighting, ventilation facilities. Banning the use of easy to produce the spark of mechanical equipment and tools. Storage area should be equipped with the right material for leakage content.

 

Uses:

Medical uses:

As the mandelic acid salt (generic methenamine mandelate, USP) it is used for the treatment of urinary tract infection. It decomposes at an acidic pH to form formaldehyde and ammonia, and the formaldehyde is bactericidal; the mandelic acid adds to this effect. Urinary acidity is typically ensured by co-administering vitamin C (ascorbic acid) or ammonium chloride. Its use had temporarily been reduced in the late 1990s, due to adverse effects, particularly chemically-induced hemorrhagic cystitis in overdose, but its use has now been re-approved because of the prevalence of antibiotic resistance to more commonly used drugs. This drug is particularly suitable for long-term prophylactic treatment of urinary tract infection, because bacteria do not develop resistance to formaldehyde. It should not be used in the presence of renal insufficiency. Methenamine in the form of cream and spray is successfully used for treatment of excessive sweating and related to it odour.

 

Histological stains

Methenamine silver stains are used for staining in histology, including the following types:

Grocott's methenamine silver stain, used widely as a screen for fungal organisms.

Jones' stain, a methenamine silver-Periodic acid-Schiff that stains for basement membrane, availing to view the "spiked" Glomerular basement membrane associated with membranous glomerulonephritis.

 

Solid fuel

Together with 1,3,5-trioxane, hexamethylenetetramine is a component of hexamine fuel tablets used by campers, hobbyists, the military and relief organizations for heating camping food or military rations. It burns smokelessly, has a high energy density of 30.0 megajoules per kilogram (MJ/kg), does not liquify while burning, and leaves no ashes. Standardized 0.149 g tablets of methenamine (hexamine) are used by fire-protection laboratories as a clean and reproducible fire source to test the flammability of carpets and rugs.

 

Food additive

Hexamethylene tetramine or hexamine is also used as a food additive as a preservative (INS number 239). It is approved for usage for this purpose in the EU, where it is listed under E number E239, however it is not approved in the USA, Russia, Australia, or New Zealand.

 

Reagent in organic chemistry

Hexamethylenetetramine is a versatile reagent in organic synthesis. It is used in the Duff reaction (formylation of arenes), the Sommelet reaction (converting benzyl halides to aldehydes), and in the Delepine reaction (synthesis of amines from alkyl halides).
