Caustic Calcined Magnesia Granular

Abstract

Caustic calcined magnesia granular (lub ntsiab tivthaiv yog MgO) tuaj yeem siv los tsim Mg (OH) 2 los ntawm txoj kev ammonium-kho.

(cov kauj ruam nram qab no: (1) MgO + 2NH4+Mg2 + 2NH3↑ + H2O thiab (2) Mg2 + 2NH3↑ + 2H2O → Mg( OH)2↓ + 2NH4+; zuag: MgO + H2O → Mg(OH)2↓).

NH4Cl, NH4NO3, thiab (NH4) 2SO4 tau nthuav tawm lub peev xwm los siv ua cov khoom nruab nrab. Hauv kev ua haujlwm no, ammonium acetate (NH4Ac) tau tshawb xyuas raws li qhov nruab nrab ncig.

Lub purity ntawm cov siv caustic calcined magnesia (ie, MgO cov ntsiab lus) yog 85 wt.%. Cov txiaj ntsig tau pom tias NH4Ac yog qhov ua tau zoo tshaj qhov nruab nrab ntawm NH4Cl, NH4NO3, lossis (NH4) 2SO4.

Txoj kev ammonium-ci tuaj yeem ua kom nrawm yog tias NH4Ac siv los ua qhov nruab nrab ntawm kev ncig. Qhov laj thawj rau kev ua haujlwm siab ntawm NH4Ac kuj tau txheeb xyuas. Los ntawm kev siv NH4Ac raws li kev ncig nruab nrab, cov paj ntoo zoo li Mg (OH) 2 precipitate tuaj yeem npaj tau rau hauv lub xub ntiag ntawm polyethylene glycol. Lub purity ntawm Mg (OH) 2 npaj yog ntau tshaj 99 wt.%.
