Ebe mgbaze nke acetic acid dị elu dị ogo 16.7, ya mere acetic acid ga-etolite ice mgbe okpomọkụ dị ala, a na-akpọkwa ya glacial acetic acid. Acetic acid bụ aha n'ozuzu, nwere ike ịdị ọcha dị elu, nwekwara ike ịdị ọcha dị ala. Glacial acetic acid na acetic acid bụ otu ihe, na-esi ísì siri ike, ihe dị iche bụ naanị ma ọ siri ike, acetic acid na-abụkarị mmiri mmiri na ụlọ okpomọkụ nke 20 Celsius C, ọ na-adịkarị ike na obere okpomọkụ nke 16 Celsius. C, nke a na-akpọkwa glacial acetic acid.
Glacial acetic acid (ihe dị ọcha), ya bụ, anhydrous acetic acid, acetic acid bụ otu n'ime ihe ndị dị mkpa organic asịd, organic ogige. Ọ na-agbake n'ime ice na obere okpomọkụ ma a na-akpọkarị glacial acetic acid. Mgbasa ụda olu n'oge ike siri ike nwere ike ime ka akpa ahụ gbajie. The flash point bụ 39 ℃, mgbawa ịgba bụ 4.0% ~ 16.0%, na ekwe ịta n'ikuku adịghị gafere 25mg/m3. Acid dị ọcha ga-adaba n'ime kristal dị ka ice n'okpuru ebe mgbaze, yabụ acetic acid a na-akpọkwa glacial acetic acid.
Na mgbakwunye, acetic acid bụ onye mbụ na-eji acid ekpomeekpo eme ihe na China. Acetic acid (36%-38%), glacial acetic acid (98%), usoro kemịkalụ CH3COOH, bụ organic monic acid, bụ isi akụrụngwa nke mmanya.
【 Usoro】
Enwere ike ịkwadebe acetic acid site na njikọ artificial na gbaa ụka. Biosynthesis, ojiji nke gbaa ụka, na-akpata naanị 10% nke ngụkọta mmepụta nke ụwa, ma ka bụ ụzọ kasị mkpa nke na-emepụta acetic acid, karịsịa mmanya, n'ihi na ọtụtụ mba nke ụkpụrụ nchekwa nri na-achọ na mmanya na nri ga-edozi ya site na. usoro ndu, na gbaa ụka na-ekewa n'ime aerobic gbaa ụka na anaerobic gbaa ụka.
(1) Usoro ịgba ụka aerobic
N'ebe ikuku oxygen zuru oke, nje bacteria Acetobacter nwere ike ịmepụta acetic acid site na nri nwere mmanya. A na-egweri cider ma ọ bụ mmanya agwakọta ya na ọka, malt, osikapa ma ọ bụ poteto. Enwere ike ịgbanye ihe ndị a n'ime acetic acid na ọnụnọ nke enzyme catalytic n'okpuru oxygen.
(2) Usoro ịgba ụka anaerobic
Ụfọdụ nje bacteria anaerobic, gụnyere ụfọdụ ndị otu Clostridium genus, na-enwe ike ịtụgharị shuga ozugbo na acetic acid na-enweghị mkpa ethanol dị ka etiti. Enwere ike ịgbanye sucrose n'ime acetic acid na enweghị oxygen.
Tụkwasị na nke ahụ, ọtụtụ nje bacteria na-enwe ike ịmepụta acetic acid site na ogige nwere nanị otu carbon, dị ka methanol, carbon monoxide, ma ọ bụ ngwakọta nke carbon dioxide na hydrogen.
