Pengfa Chemical—Onye Ọkachamara Nrụpụta Acetic Acid

      Acetic acid, mmiri mmiri na-enweghị agba, nwere isi ísì siri ike.Ebe na-agbaze nke acetic acid bụ 16.6 ℃, isi ihe na-esi ísì bụ 117.9 ℃, njupụta nke ikwu bụ 1.0492 (20/4 ℃), na ntinye ntụgharị bụ 1.3716.Acid dị ọcha nwere ike ịmepụta ice siri ike dị n'okpuru 16.6 Celsius C, ya mere a na-akpọkarị ya glacial acetic acid.Acetic acid bụ ihe dị mkpa organic kemịkalụ akụrụngwa, tumadi eji kwadebe vinyl acetate monomer (VAM), cellulose acetate, acetic anhydride, terephthalic acid, chloroacetic acid, polyvinyl mmanya, acetate na metal acetate.

A na-eji acetic acid eme ihe n'ọtụtụ ebe na njikọ organic nke bụ isi, ọgwụ, ọgwụ pesticides, ibipụta na agba, textiles, nri, agba, adhesives na ọtụtụ ụlọ ọrụ ndị ọzọ.Acetic acid bụ ihe dị mkpa kemịkalụ akụrụngwa.Teknụzụ mmepụta mmepụta ihe nke acetic acid gụnyere: methanol carbonylation method, acetaldehyde oxidation, ethylene direct oxidation and light oil oxidation.N'ime ha, methanol carbonylation bụ teknụzụ kachasị eji eme ihe, na-aza ihe karịrị 60% nke ikike nrụpụta zuru ụwa ọnụ, usoro a ka na-etolite.

Ike mmepụta acetic acid zuru ụwa ọnụ anọwo na-egosi ọganihu elu, na ọchịchọ ya zuru ụwa ọnụ ga-etokwa na nkezi ọnụego kwa afọ nke ihe dịka 5% n'ime afọ ole na ole sochirinụ, nke 94% nke ikike mmepụta acetic acid ọhụrụ zuru ụwa ọnụ ga-eme na Asia, na mpaghara Eshia ga-abụkwa n'ọdịnihu.Na-eduga ngwa ngwa uto nke ahịa ahịa zuru ụwa ọnụ n'ime afọ ise.

ngwa:
1. Acetic acid mmepụta: a na-ejikarị eme ihe na njikọ nke acetic anhydride, acetate, terephthalic acid, vinyl acetate / polyvinyl alcohol, cellulose acetate, ketene, chloroacetic acid, haloacetic acid, wdg;
2. Ọgwụ: Acetic acid na-eji dị ka ihe mgbaze na ọgwụ akụrụngwa, tumadi na-eji na mmepụta nke penicillin G potassium, penicillin G sodium, procaine penicillin, antipyretic mbadamba, sulfadiazine, sulfamethoxazole, norfloxacin, ciprofloxacin Floxacin, acetylsalicylic acid, phenacin. prednisone, caffeine, wdg;
