Kaʻina huahana:
Loaʻa ia mai ka hopena o ka ethylenediamine me ka chloroacetic acid, a i ʻole mai ka hopena o ka ethylenediamine me formaldehyde a me ka sodium cyanide.
Nā hiʻohiʻona:
ʻO EDTA 4NA ka pauka crystalline keʻokeʻo he 4 ka wai aniani, hiki ke hoʻoheheʻe ʻia i loko o ka wai, he alkaline ka hoʻonā wai, hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, hiki ke nalowale i ka ʻāpana a i ʻole nā wai aniani āpau i ka wela kiʻekiʻe.
Nā noi:
ʻO EDTA 4NA he mea hoʻohana nui ʻia metala ion chelator.
1. Hiki ke hoʻohana 'ia i loko o ka lole lole no ke kala, hoʻonui kala, hoʻomaikaʻi i ka waihoʻoluʻu a me ka olinolino o nā lole hoʻoluʻu.
2. Hoʻohana ʻia e like me ka additive, activator, metala ion masking agent a me ka mea hoʻoulu i ka ʻoihana ʻoihana butadiene.
3. Hiki ke hoʻohana 'ia i loko o ka maloʻo acrylic oihana e offset metala keakea.
4. Hiki ke hoʻohana ʻia ʻo EDTA 4NA i ka mea holoi wai e hoʻomaikaʻi i ka maikaʻi o ka holoi ʻana a me ka hopena holoi.
5. Hoʻohana ʻia e like me ka wai palupalu, hoʻomaʻemaʻe wai, hoʻohana ʻia no ka mālama ʻana i ka maikaʻi o ka wai.
6. Hoʻohana ʻia e like me ka synthetic rubber catalyst, acrylic polymerization terminator, paʻi ʻana a me ke kala ʻana i nā mea kōkua, etc.
7. Hoʻohana ʻia ia no ka titration i ka loiloi kemika, a hiki ke titrate pololei i nā ʻano metala ion.
8. Ma waho aʻe o nā mea i hoʻohana ʻia ma luna nei, hiki ke hoʻohana ʻia ʻo EDTA 4NA i ka lāʻau lapaʻau, kemika o kēlā me kēia lā, ka hana pepa a me nā ʻoihana ʻē aʻe.
