Acetic acid, mvura isina ruvara, ine hwema hunonhuwa.Iko kunyunguduka kweacetic acid i16.6 ℃, iyo yekubikira i117.9 ℃, density yehukama i1.0492 (20/4 ℃), uye refractive index i1.3716.Pure acetic acid inogona kugadzira ice-like solid pazasi 16.6 °C, saka inowanzonzi glacial acetic acid.Acetic acid inokosha organic chemical raw material, inonyanya kushandiswa kugadzira vinyl acetate monomer (VAM), cellulose acetate, acetic anhydride, terephthalic acid, chloroacetic acid, polyvinyl doro, acetate uye metal acetate.
Acetic acid inoshandiswa zvakanyanya mukutanga organic synthesis, mushonga, mishonga yezvipembenene, kudhinda uye dhayi, machira, chikafu, pendi, anonamira uye mamwe maindasitiri mazhinji.Acetic acid yakakosha kemikari mbishi zvinhu.Iwo maindasitiri ekugadzira matekinoroji eacetic acid anonyanya kusanganisira: methanol carbonylation nzira, acetaldehyde oxidation, ethylene yakananga oxidation uye mafuta akareruka oxidation.Pakati pavo, methanol carbonylation ndiyo inonyanya kushandiswa tekinoroji, inoverengera inopfuura 60% yehuwandu hwepasirese kugadzirwa kwesimba, uye maitiro aya achiri kukura.
Hurukuro yekugadzira acetic acid yepasi rose yave kuratidza kukwira kumusoro, uye kudiwa kwayo kwepasirese kuchakurawo paavhareji yegore negore inosvika 5% mumakore mashoma anotevera, ayo 94% yepasi rose itsva acetic acid yekugadzira ichaitika Asia, uye nzvimbo yeAsia ichave zvakare mune ramangwana.Kutungamira kukurumidza kukura kwemusika wepasi rose kudiwa mukati memakore mashanu.
