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 methenamine role, but does not melt. Release hydrogen cyanide when heated to 300 ℃, when the temperature rises again Shandong methenamine, the decomposition of methane, hydrogen and nitrogen. The relative density of 1.331 (20/4 ℃), a flash point of 250 ℃. Almost odorless, sweet and bitter. Soluble in water and chloroform, insoluble in 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, carried out in an alkaline solution condensation reaction, the reaction temperature was maintained at 50-70 ℃ methenamine nature, the material was cooled into the film vacuum evaporator at 60-80 Under ℃ evaporation to a concentration increased from 24% to 38% -42%, and then the reaction mixture 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), to chemical Dangerous Goods Safety Management Regulations and Rules (the Labor Fa [1992] No. 677), the workplace safe use of chemicals ([ 1996] labor department No. 423) regulations for 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 Class 4.1 Flammable solids. Uses: hexamethylene tetramine is mainly used as a curing agent for resins and plastics, amino plastics catalyst and a blowing agent, rubber vulcanization accelerator (accelerator H), textiles shrink-proof agent. Hexamethylene tetramine is the synthesis of organic materials in the pharmaceutical industry for the production of chloramphenicol. Hexamethylene tetramine urinary system can be used as a disinfectant, which itself has no antibacterial effect on gram-negative bacteria effectively. 20% of the solution for the treatment of underarm odor, sweaty feet, tinea and so on. It is mixed with sodium hydroxide and sodium phenol, phosgene gas masks do absorbers. 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. [1] 4 Hazard Overview Edit Risk category: pathways: health hazards: under production conditions, the main cause dermatitis and eczema. Pleomorphic rash, itching methenamine, limited contact area since the beginning of the future can be spread, even throughout the body. Environmental hazards: Explosion hazard: This product is flammable, corrosive, can cause the body burns, exposure can cause dermatitis, itching.
