3. Njira Yopangira Methanol Carbonalysis
Kutulutsa mpweya wa methanol ndi njira yatsopano yopangira propionic acid. Pogwiritsa ntchito methanol ngati zopangira, izi zimachitika pamaso pa chothandizira kupanga njira yapakati ya carbonyl yochokera ku methanol, yomwe kenako imasungunuka kuti ipange propionic acid.
4. Njira Yopangira Oxidation ya Propylene
1. Kukonzekera Zinthu Zopangira
Zipangizo zopangira propylene oxidation ndi monga propylene, mpweya, ndi madzi. Propylene imapezeka kuchokera ku mafakitale oyeretsera kapena zomera zosweka, pomwe mpweya umachokera ku mayunitsi olekanitsa mpweya.
2. Njira Yochitirapo Kanthu
Kutentha: Propylene ndi mpweya zimatenthedwa padera kutentha koyenera kuti zitsimikizire kuti zimachitika bwino.
Kuchita Zinthu Mogwirizana ndi Mphamvu: Propylene yotenthedwa ndi mpweya zimasakanizidwa ndi kuchitidwa zinthu motsatira mphamvu ya chothandizira. Gawoli limachitika kutentha kwambiri komanso kupanikizika, nthawi zambiri pa 250–350°C ndi 1–3 MPa.
Kuziziritsa: Chochitacho chimaziziritsidwa kutentha kwa chipinda kudzera mu choziziritsira kuti chigwiritsidwenso ntchito.
3. Kulekanitsa ndi Kuyeretsa
Pambuyo pa zomwe zachitika, mankhwalawa amakhala ndi zinthu zambiri zosafunika komanso zopangira zosagwiritsidwa ntchito, zomwe zimafuna kulekanitsidwa ndi kuyeretsedwa:
Kulekanitsa: Madzi, propylene yosakhudzidwa, ndi zinthu zina zodetsedwa zimalekanitsidwa ndi chinthucho pogwiritsa ntchito zinthu zolekanitsa.
Kuyeretsa: Propionic acid yolekanitsidwa imayeretsedwa kudzera mu distillation, extraction, ndi njira zina kuti ipeze propionic acid yoyera kwambiri.

Propionic Acid – Shandong Pulisi Chemical Co., Ltd.           info@pulisichem.cn
Shandong Pulisi Chemical Co., Ltd. ndi kampani yodalirika komanso yopanga propionic acid yoyera kwambiri (CH₃CH₂COOH, CAS 79-09-4) ku China, yomwe imapereka zinthu zapamwamba kwambiri zomwe zimagwiritsidwa ntchito m'mafakitale, chakudya, ndi mankhwala. Propionic acid yathu ndi madzi opanda mtundu, owononga omwe ali ndi fungo lokhazika mtima pansi, omwe amasungunuka kwambiri m'madzi ndi zinthu zachilengedwe, komanso khalidwe lake limagwirizana ndi miyezo yapadziko lonse lapansi.
Yopangidwa kudzera mu njira zamakono zoyeretsera ndi kulamulira bwino khalidwe, propionic acid yathu imakwaniritsa zofunikira za mafakitale ndi chakudya, kuonetsetsa kuti palibe kuipitsidwa komanso magwiridwe antchito okhazikika. Imagwira ntchito ngati chosungira chofunikira, chothandizira bowa, komanso chothandizira mankhwala: imagwiritsidwa ntchito kwambiri pakusunga chakudya (zophikidwa, mkaka), kusungira chakudya ndi tirigu (kuletsa kukula kwa nkhungu), kupanga mchere wa propionate (sodium propionate, calcium propionate), komanso kupanga mankhwala ophera udzu, mapulasitiki, zonunkhira, ndi mankhwala ochiritsira.
Ku Pulisi Chemical, timaika patsogolo kukhazikika kwa malonda, chitetezo, komanso kupezeka kwa zinthu kosatha. Propionic acid yathu imayikidwa m'ma ng'oma wamba kapena m'mathanki a ISO, ndi njira zotumizira zosinthika kuti zikwaniritse zosowa zosiyanasiyana za makasitomala padziko lonse lapansi. Mothandizidwa ndi zaka zambiri zogwira ntchito popanga mankhwala komanso gulu la akatswiri pa kafukufuku ndi chitukuko, timatsimikizira kuti zinthu zili bwino nthawi zonse, mitengo yampikisano, komanso chithandizo chaukadaulo chokwanira kwa ogwirizana nawo padziko lonse lapansi.
