Katrangan |
Asam Acrtic Acid minangka cairan utawa kristal tanpa cairan sing asem, kaya cuka lan minangka salah sawijining asam karboksilat sing paling gampang lan minangka reagen iskemik sing akeh digunakake. Asam asetat duwe aplikasi wiyar minangka reagen laboratorium, ing produksi selulosa asetat utamane kanggo film fotografi lan polibinil asetat kanggo lem kayu, serat sintetis, lan bahan kain. Asam asetat uga wis akeh digunakake minangka agen turun tumurun lan acidityregulator ing industri panganan . |

|
Properti fisik |
Asam Acrtic minangka asam karboksilat sing ringkih kanthi ambu sing pedhot sing ana cair asa ing suhu ruangan. Iki bisa uga asam pertama sing diprodhuksi kanthi jumlah akeh. Jeneng asetat asale saka acetum, yaiku tembung Latin kanggo â € œsourâ € lan ana gandhengane karo kasunyatan manawa asam asetat bisa nyebabake rasa pait jus sing difermentasi. |

|
Metode Produksi |
Asam Acrtic biasane digawe dening salah siji saka telung rute: acetaldehydeoxidation, nglibatake hawa langsung utawa oksidasi oksidasi cairan asetaldehida nalika ana asetat mangan, asetat kobalt, utawa asetat tembaga; oksidasi fase cairan butane utawa naphtha; karbonilasi metanol nggunakake macem-macem teknik. |
