Properties Kimia |
Asam Prosionic, Ch3CH2COOH, uga dikenal minangka Propanoic Asam lan Asam Methylacetic, minangka cairan sing ora ana warna, yaiku cairan tanpa warna sing ora ana ing 140 ° C (284 saka). Iku kebak keberone. Nduwe ambu ora enak lan larut ing banyu lan alkohol. Ambang ambu yaiku 0.16 ppm. Asam Prosionik minangka asam monocarboxyatic aliphat. Asam Propanis digunakake ing solusi elektrolasi nikel, minyak wangi, rasa gawean, farmasi, lan manufaktur propionat. |
|
Nggunakake |
Asam propionik digunakake ing Propeionates Propeionof sing digunakake minangka andpreser pemeriksaan cetakan kanggo pari-parian lan chip kayu, ing pabrik rasa lan minyak, lan minangka agen esterifying. |

Cara produksi |
Asam propionik bisa dipikolehi saka pulp kayu mbuwang omben-omben kanthi fermentasi. Sampeyan uga bisa disiapake saka etilena, karbon monoksida lan uap; saka etanol lan karbon monoksida nggunakake katalis triffuoride boron; saka gas alam; utawa minangka produk ing pyrolysis kayu. Asam propionik murni banget bisa dipikolehi saka propionitrile. Asam propionik bisa ditemokake ing produk susu kanthi jumlah cilik. |
