Nature Description: white crystalline powder or colorless hygroscopic shiny diamond crystal, flammable. Melting point 263 ℃, such as melting point that is over this sublimation and decomposition, but does not melt. When heated to release hydrogen cyanide 300 ℃, when the temperature rises again methenamine, the decomposition of methane, hydrogen, and nitrogen. The relative density of 1.331 (20/4 ℃), a flash point of 250 ℃. Methenamine effect almost odorless, sweet and bitter. Soluble in water and chloroform methenamine nature, insoluble carbon tetrachloride, acetone, benzene and ether, insoluble in petroleum ether. Decomposed into ammonia and formaldehyde in a weak acid solution. Contact with the flame, the flame immediately burn and produce smoke-free. Volatile. Production methods: from formaldehyde and ammonia condensation. The formaldehyde solution was placed in the reactor through ammonia condensation reaction in alkaline solution, the reaction temperature was maintained at 50-70 ℃, the material was cooled into the film vacuum evaporator, at 60-80 ℃ to make Its concentration is increased from 24% to 38% -42%, and the reaction solution was filtered by vacuum evaporation and crystallization, filtration drying derived products methenamine. Edit Regulatory Information Regulatory Information Chemical Dangerous Goods Safety Management Regulations (February 17, 1987 the State Council), the Regulations dangerous chemicals safety management regulations (the Labor Fa [1992] No. 677) methenamine spot, workplace safety use Chemicals ([1996] labor department No. 423) and other regulations, the safe use of hazardous chemicals, production, storage, transport, handling, etc. are made corresponding provisions; commonly used classification of dangerous chemicals and signs (GB 13690 -92) the substance is classified as a Class 4.1 Flammable solids. For the manufacture of pesticides. Hexamethylene tetramine with fuming nitric acid, can be obtained highly explosive RDX, referred to as RDX. Hexamethylene tetramine can be used as the determination of bismuth, indium, manganese, cobalt, thorium, platinum, producing magnesium, lithium, copper, uranium, beryllium, tellurium, bromide, iodide and the like reagents chromatography reagents. Military fuel is commonly used. Resins and plastics used as a curing agent, rubber vulcanization accelerator (accelerator H), textiles shrink-proof agent, and used for making fungicides, explosives and so on. Medicinal, acidic urine after oral administration of the case of the decomposition of formaldehyde into sterilization, used for mild urinary tract infection; outside used to treat ringworm, antiperspirants, underarm odor treatment. Mixed with caustic soda and sodium phenol for gas masks as phosgene absorber. Methenamine Low | hexamine | Chemical offers three levels by the Jinan Chemical Co., Ltd. three levels.
