Magnesium acetate CAS 142-72-3
Magnesium acetate, yomwe imadziwikanso kuti "magnesium acetate". Fomula ya mankhwala Mg (C2H3O2) 2. Kulemera kwa molekyulu ndi 142.4. Makristalo oyera kapena opanda mtundu. Sungunulani pa 323 ℃ ndikuwola nthawi imodzi. Kuchulukana kwa 1.42, kumasungunuka mosavuta, kumasungunuka kwambiri m'madzi, sikulowerera m'madzi, komanso kumasungunuka mu methanol ndi ethanol. Magnesium carbonate imatha kusungunuka mu acetic acid aqueous solution, kusefedwa, ndipo filtrate imasanduka nthunzi mwachilengedwe mu chowumitsira cha sulfuric acid chokhazikika kuti chikhale ndi tetrahydrate. Kenako imatenthedwa mpaka kulemera kosasintha pa 130 ℃ kuti ipange magnesium acetate.

Magnesium acetate imagwiritsidwa ntchito posindikiza ndi kupukuta utoto, komanso ma analytical reagents ndi ma catalysts a olefin polymerization. LD50 yobayira m'mitsempha ya mbewa ndi 18mg/kg. Magnesium acetate imagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana. Mu ma laboratories a mankhwala, imagwiritsidwa ntchito kwambiri ngati choletsa kuwononga ndi kuwononga chitsulo cha magnesium. Magnesium acetate imagwiritsidwanso ntchito ngati chowonjezera ku magnesium, kupatsa thupi chinthu chofunikira cha magnesium. Ingagwiritsidwenso ntchito ngati chothandizira, desiccant, komanso chothandizira kuchotsa magnesium oxide.
Kawirikawiri amanyamula mu 25kg/ng'oma, ndipo amathanso kupangidwa mwamakonda.
