Ammonium Heptamolybdate

Ammonium Molybdate

ammonium heptamolybdateProduct Taw qhia:

Tsis muaj xim los yog lub teeb daj ntsuab columnar crystals. Dissolved nyob rau hauv 2.3 qhov chaw ntawm dej, insoluble nyob rau hauv ethanol, decomposes raws li kev sib cuag nrog acid. Thaum rhuab mus rau 90 degree, ib molecule ntawm crystal dej yog ploj, thiab thaum rhuab mus rau 190 degree, nws decomposes. Tus nqi pH ntawm 5% aqueous tov yog 5.0-5.5. Tus txheeb ze ntom ntom yog 2.498.

Kev npaj ammonium heptamolybdate:

Sib tov cov khoom lag luam crushed molybdenum trioxide, dej, thiab ammonia tov kom yaj lawv. Lim thiab ntxuav cov tshuaj insoluble nrog ammonia dej. Ntxiv ammonium sulfide tov rau filtrate, tshav kub thiab lim. Thaum evaporating thiab tsom mus rau qhov sib txheeb ze ntawm 141, ntxiv ammonia dej thiab do tsis tu ncua kom txog thaum muaj cov ntxhiab tsw muaj zog ammonia. Txias thiab lim kom tau txais cov ntshiab ammonium molybdate.

ammonium heptamolybdate Lub hom phiaj:

Siv los ua reagent rau kev txiav txim siab phosphates, npib tsib xee, germanium, selenium dioxide, arsenates, alkaloids, thiab txhuas. Reagents rau chromatographic tsom xam. Siv los ua cov catalyst hauv kev lag luam roj av, nws tseem yog cov khoom siv raw rau hmoov metallurgy ntawm molybdenum, yees duab, ceramic glazes, thiab pigments.
