| | Ammonium octamolybdate Usage And Synthesis |
| Description | Ammonium octamolybdate, (NH4)4Mo8O26 or "AOM," is a commercially-useful molybdenum composition and is available in a variety of phases or isomers. The chemical compound referred to as ammonium octamolybdate is also commonly known variously as "diammonium catena-tetramolybdate," "ammonium tetramolybdate," "tetrammonium hexamolybdate," or by CAS number 12411-64-2. While α-AOM is commonly used as a smoke suppressant in various types of plastic materials, it may also be used in the formation of various types of optically-markable ink compositions. Such ink compositions change color in response to irradiation from light, typically from a laser, although other light sources may be used. The color change is the result of a change in oxidation state and/or the formation of non-stoichiometric products of the AOM constituent of the ink composition. | | Uses | Ammonium octamolybdate is a molybdenum-based coordination compound used as a modifier for its flame-retardant properties, such as in the patented preparation of flame retardant and wear-resistant foamed asphalt. After modification of ammonium octamolybdate from its cluster geometry to a one-dimensional coordination polymer, ammonium octamolybdate is used as an olefin epoxidation catalyst. | | Application | For industrial usage, plastic flame retardants, used in nylon, rubber, resin. | | Flammability and Explosibility | Not classified | | Synthesis | CN201010532716.8 provides a preparation method of lanthanum-doped ammonium octamolybdate with fine particle size and uniform distribution for doping, which can effectively improve the homogeneity of the dispersed phase after doping for the purpose of doping lanthanum-doped ammonium octamolybdate.
Take 134.3g of ammonium dimolybdate, 160.9g of high purity, and 675mL of soft water.Firstly, add the ammonium dimolybdate and the soft water into the crystallization tank, and heat and stir, the heating temperature is 80, and the stirring speed is 80r/min; when the dissolution is finished, gradually add the high purity molybdenum oxide, so that the pH value of the solution is adjusted to about 4.0; to the solution, slowly add 36mL of 25g/L lanthanum nitrate solution, and then Add the remaining high-purity molybdenum dioxide, adjust the pH value to between 2.0, heating and stirring at 80 for 10 minutes to replenish water to continue the reaction for 2h, discharging, pumping filtration, drying, drying temperature of 100 for 6 hours, that is, lanthanum-doped percentage of 0.3% of the ammonium octamolybdate.
