Hāʻawi hale hana EDTMPA mai Kina CAS: 1429-50-1 me ke kūlana kiʻekiʻe
Waiwai
ʻO EDTMPA ka pauka keʻokeʻo keʻokeʻo ma ka lumi wela, me ka helu heheʻe 215-217ºC, paʻakikī ke hoʻoheheʻe ʻia i ka wai, ʻoi aku ka liʻiliʻi o ka solubility i ka 5% ma ka lumi wela, maʻalahi ka hoʻoheheʻe ʻia i ka amonia. Loaʻa i ka EDTMPA ka mana chelating ion metala, ʻoi aku ka nui o ka chelating mau me ka ion cuprum ma mua o ka EDTA.
Hōʻike
| Papa kuhikuhi | Kūlana |
| Ka nana aku | ʻO ka pauka aniani keʻokeʻo |
| ʻAikika ikaika (e like me EDTMPA) ma ka wt % | 96.0 min |
| ʻO ka nui o ka waikawa phosphonic (e like me PO43-) ma ka wt% | 82.0 min |
| Klorida (Cl-) % | 0.1 ka nui |
| Māmā e ka wt % | 2.0 ka nui |
| Fe ma ka mg/L | 5.0 ka nui |
| pH (1% wai hoʻonā) | 2.0 ka nui |
Hoohana Huahana
ʻO ka EDTMPA kahi mea hoʻomaʻemaʻe kiʻekiʻe ʻaʻole ʻona, me ka ikaika chelating ikaika no nā ion metala, hiki ke hoʻohana ʻia i loko o ka ʻoihana uila e like me ka mea hoʻomaʻemaʻe no nā ʻāpana semiconductor o nā kaapuni i hoʻohui ʻia, a ma ke ʻano he mea lawe i nā mea radioactive i ka ʻoihana lāʻau no ka ʻike. a me ka lapaau ana i na mai.
Pūʻolo a me ka waiho ʻana
EDTMPA paʻa: 25kg / ʻeke, koi ʻia nā mea kūʻai aku.
Mālama ʻia no 12 mahina ma kahi lumi malu a me kahi maloʻo.
