Acid Glacial Acetic Dị Ọcha Dị Elu – Ihe na-akpali akpali dị iche iche na ihe mgbaze akwụkwọ ndụ akwụkwọ ndụ maka njikọ organic

Ngwaahịa a bụ glacial acetic acid nke a na-enyocha (ịdị ọcha ≥99.5%), ihe dị mkpa na mmepụta organic. Acid siri ike pụrụ iche ya, ịdị ọcha dị elu, na ezigbo mgbaze na-eme ka ọ bụrụ ihe na-akpali akpali na ihe mgbaze pụrụ iche maka esterification, acylation, na condensation mmeghachi omume. Glacial acetic acid na-eje ozi dị ka ihe dị mkpa maka imepụta ihe ndị sitere na carboxylic acid (dịka ọmụmaatụ, esters, amides) ma a na-anabata ya nke ọma na kemịkalụ akwụkwọ ndụ akwụkwọ ndụ n'ihi obere nsí ya, ndakọrịta gburugburu ebe obibi, na ike ịmegharị ya.

Uru Ndị Dị Mkpa

1. Ọcha na Ịkwụsi Ike Dị Elu nke Ukwuu:
Ịdị ọcha ≥99.5% na-eme ka mmeghachi omume dị irè, nke na-arụpụta ihe dị elu, dị mma maka njikọta dị nro (dịka ọmụmaatụ, ihe ndị na-emepụta ọgwụ, ihe kristal mmiri mmiri).
2. Ọdịdị dị iche iche:
Ọkwa Ụlọ Nyocha: Dabara adaba maka nhazi obere mmeghachi omume na ọmụmụ ihe gbasara usoro.
Ọkwa Ụlọ Ọrụ: Dakọtara na usoro mmepụta ihe na-aga n'ihu na nke na-aga n'ihu, gụnyere ihe nrụpụta microwave na sistemụ nrụgide dị elu.
3. Nchekwa na Nkwado:
Nkwakọ ngwaahịa e mechiri emechi (imepụta ihe na-anaghị agbapụta mmiri + ihe na-eme ka gas ghara ịgbapụta mmiri) na-egbochi ikuku na mmetọ, na-agbaso ụkpụrụ gburugburu ebe obibi ISO 14001.
A na-emegharị ya site na iji usoro distillation ma ọ bụ adsorption, na-ebelata ihe mkpofu site na ihe karịrị 70%.
4. Ọnụ ego-arụmọrụ:
Na-anọchi asịd na-emebi emebi (dịka ọmụmaatụ, sọlfọric acid) dị ka ihe na-akpali acid siri ike, na-ebelata ire ere akụrụngwa.
Na-ejikọta ya na mmiri ionic iji mee ka mmepụta dịkwuo mma ma belata oge mmeghachi omume.
