Makenesium acetate CAS 142-72-3
ʻO ka magnesium acetate, i ʻike ʻia hoʻi ʻo "magnesium acetate". ʻO ke ʻano kemika Mg (C2H3O2) 2. ʻO ke kaumaha molekala he 142.4. Nā kristal keʻokeʻo a ʻaʻohe kala. Hoʻoheheʻe ʻia ma 323 ℃ a palaho i ka manawa like. ʻO ka nui pili 1.42, maʻalahi ka deliquescent, hoʻoheheʻe nui ʻia i ka wai, kūlike ʻole i ka wai, a hoʻoheheʻe ʻia hoʻi i ka methanol a me ka ethanol. Hiki ke hoʻoheheʻe ʻia ka magnesium carbonate i loko o ka hopena wai waikawa acetic, kānana ʻia, a hoʻoheheʻe maoli ʻia ka filtrate i loko o kahi mea hoʻomaloʻo waikawa sulfuric i hoʻopaʻa ʻia e hoʻoulu i ka tetrahydrate. A laila hoʻomehana ʻia i ke kaumaha mau ma 130 ℃ e hana i ka magnesium acetate.

Hoʻohana ʻia ka magnesium acetate no ka paʻi ʻana a me ka hoʻoluʻu ʻana, a me nā reagents analytical a me nā catalysts no ka polymerization olefin. ʻO ka LD50 no ka injection intravenous i loko o nā ʻiole he 18mg/kg. Hoʻohana nui ʻia ka magnesium acetate ma nā ʻano like ʻole. I loko o nā keʻena hoʻokolohua kemika, hoʻohana pinepine ʻia ia ma ke ʻano he mea mālama a me ka mea pale i ka palaho no ka metala magnesium. Hoʻohana pū ʻia ka magnesium acetate ma ke ʻano he mea hoʻohui i ka magnesium, e hāʻawi ana i ke kino me ka mea magnesium e pono ai. Hiki ke hoʻohana ʻia ma ke ʻano he catalyst, desiccant, a me ka mea hana no ka wehe ʻana i ka magnesium oxide.
Hoʻopili pinepine ʻia i loko o 25kg / pahu, a hiki ke hana ʻia kahi pūʻolo i hoʻopilikino ʻia.
