intro

Aha kemịkalụ nke acetic acid bụ acetic acid, usoro kemịkal CH3COOH, na ọdịnaya nke 99% acetic acid bụ crystallized ka ọ bụrụ ice udi n'okpuru 16 Celsius C, makwaara dị ka glacial acetic acid.Acetic acidenweghị agba, mmiri soluble, nwere ike miscible na mmiri n'ụzọ ọ bụla, na-agbanwe agbanwe, bụ ihe na-adịghị ike organic acid.

Dị ka acid organic, acetic acid abụghị naanị nke ejiri ya mee ihe na njikọ organic, ụlọ ọrụ kemịkalụ organic, nri, ọgwụ na ụlọ ọrụ ndị ọzọ, kamakwa ejiri ya na ụlọ ọrụ ịsa na ịcha akwa.

Acid-base neutralization nke acetic acid na ịsacha na ịcha ụlọ ọrụ

Acetic acidn'onwe ya bụ acidic na-esighị ike ma nwee ike ịpụpụ ya na ntọala.

Maka agba agba mmiri na-edozi mmiri nwere hydroxyl na sulfonic acid otu, eriri eriri na-adịghị mma alkali eguzogide (dị ka silk, rayon, ajị), n'okpuru ọnọdụ nke mmanya, ọ na-adabara agba na agba idozi nke eriri.

Ya mere, ụfọdụ uwe ndị na-adịghị mma na-eguzogide alkaline na nkwụsị dị mfe na usoro ịsa ahụ nwere ike ịgbakwunye na obere acetic acid n'ime akwa akwa akwa iji dozie agba nke uwe.

Site n'echiche a,acetic acida na-ejikarị eme ihe na ụlọ ọrụ ịsacha na ịcha akwa, ma n'ime usoro ngwa ahụ kwesịkwara ịṅa ntị n'ihe ndị a.

Maka akwa nwere eriri acetic acid, mgbe ị na-eji acetic acid wepụ ntụpọ, ị kwesịrị ịkpachara anya ka ị ṅaa ntị na ntinye acetic acid adịghị oke elu. Nke a bụ n'ihi na fiber acetate bụ osisi, owu owu na ihe ndị ọzọ cellulosic na acetic acid na acetate, adịghị mma iguzogide mmanya, acid siri ike nwere ike imebi eriri acetate. Mgbe etinyere ntụpọ na eriri acetate na akwa nwere eriri acetate, isi ihe abụọ kwesịrị iburu n'uche:

(1) Nchekwa ojiji nke acetic acid bụ 28%.

Akpachara anya maka iji acetic acid bụ ndị a:

(1) Zere kọntaktị na anya, ma ọ bụrụ na kọntaktị na elu ịta nke fermented acid, kpochaa na mmiri ozugbo.
