Molecular formula : C5H10N6O2
MW : 186.17
CAS No. 41-25-7
nature : short cream-colored powder. The temperature of 207 ° C, 210-220 ° C decomposition temperature, the air 190-200 ° C decomposition. Soluble DMF, acetone, methyl ethyl ketone, slightly soluble in water, alcohol, chloroform-soluble, almost insoluble in ether. Flammable, and acid or acid fog can quickly contact with fire.
Preparation : 6 Hexamethylenetetramine (Urotropine) derived by nitrosation. Urotropine of water and sodium nitrite dissolved in dilute sulfuric acid was added dropwise under stirring (or diluted hydrochloric acid), the reaction temperature is controlled at 0 ° C Nitrosation after addition of a small amount of ammonia and nitrite. Resultant by leaching, washing, laundry, drying, sifting derived products. H purity industrial foam �98%. Raw material consumption (kg / t) 720 Urotropine sulfate sodium nitrite 1,018 (93%) 800 chlorinated water (20%) 650
purposes : the goods for widespread use of blowing agents, mainly used in the manufacture of sponge rubber, plastics used for PVC. The thermal decomposition products of nitrogen into where the hole, the broad-minded, not foam high efficiency. The use of salicylic acid, adipic acid, phthalic acid and other organic acids or urea for foaming agents, can reduce the decomposition temperature, adjust the 90-130 ° C range. The decomposition products of heat and therefore tend to make products thick in the central part of charred, but a product of decomposition stench. With urea and will be used to eliminate the smell. PVC and can be used as a copolymer, polyolefin, polystyrene, polyamide, polyester, phenolic resins, poly vinylidene chloride, polysiloxane, Penton butadiene, ethylene and propylene copolymer, poly ethylene oxide and its elastomer foam. The goods on the skin and mucous membrane irritation with the middle, containing more than 1% formaldehyde are toxic. The production process to the attention of explosion.
