Ethylene is a colorless and flammable gas with the chemical formula C2H4, representing one of the simplest hydrocarbon compounds with a double bond between carbon atoms. It is a natural plant hormone responsible for regulating various growth and developmental processes in plants, including ripening and flowering. Ethylene has significant industrial importance, as it is widely used in the production of plastics, particularly polyethylene, which is one of the most commonly used plastics worldwide. It also finds application in the chemical industry for the synthesis of various organic compounds. Ethylene's dual role in plant biology and industrial chemistry highlights its importance in both the natural world and human technology.
1.Used as an intermediate in organic synthesis. It is liquid, soluble in organic solvent, slightly soluble in water. It is a low toxicity, high efficiency and broad spectrum anti-mildew agent. It has strong killing effect on mold and can achieve ideal anti-mildew effect.
2.It can be widely used in coating, paint, lubricating oil, shoe polish, leather chemistry, wood products and cultural relics protection and many other products.
Hexamethylene or methenamine is a heterocyclic organic compound with the formula (CH2)6N4. This white crystalline compound is highly soluble in water and polar organic solvents. It has a cage-like structure similar to adamantane. It is useful in the synthesis of other chemical compounds, e.g., plastics, pharmaceuticals, rubber additives. It sublimes in vacuum at 280 �°C.
Application
The dominant use of hexamethylenete tramine 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.
Medical uses
As the mandelic acid salt (methenamine mandelate) or the hippuric acid salt (methenamine hippurate), it is used for the treatment of urinary tract infection.
Histological stains
Methenamine silver stains are used for staining in histology,
Solid fuel
Together with 1,3,5-trioxane, used by campers, hobbyists, and relief organizations for heating camping food.
Reagent in organic chemistry
Hexamethylene 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).
Explosives
Hexamethylene is the base component to produce RDX
