3. Inqubo ye-Methanol Carbonalylation
I-Methanol carbonylation iyindlela entsha yokukhiqiza i-propionic acid. Kusetshenziswa i-methanol njengezinto zokusetshenziswa, ukusabela kwenzeka lapho kukhona i-catalyst yokwakha uhlelo oluphakathi lwe-carbonyl olusekelwe ku-methanol, olube seluxutshwa ukuze kukhiqizwe i-propionic acid.
4. Inqubo Yokuxosha I-Propylene
1. Ukulungiswa Kwezinto Ezingavuthiwe
Izinto zokusetshenziswa zokuxiliswa kwe-propylene zifaka phakathi i-propylene, umoya, namanzi. I-propylene itholakala ezindaweni zokuhluza noma ezitshalweni eziqhekekayo, kuyilapho umoya utholakala kumayunithi okuhlukanisa umoya.
2. Inqubo Yokusabela
Ukushisa: I-Propylene nomoya kushiswa ngokwahlukana emazingeni okushisa afanele ukuqinisekisa ukuthi ukusabela kuqhubeka kahle.
Ukusabela Okusheshayo: I-propylene eshisiwe kanye nomoya kuyaxutshwa futhi kuphendulane lapho kukhona i-catalyst. Lesi sinyathelo senzeka ngaphansi kwezimo zokushisa okuphezulu kanye nengcindezi, ngokuvamile ku-250–350°C kanye ne-1–3 MPa.
Ukupholisa: Umkhiqizo wokusabela upholiswa ekushiseni kwegumbi nge-cooler ukuze uqhubeke nokucutshungulwa.
3. Ukuhlukaniswa Nokuhlanzwa
Ngemva kokusabela, umkhiqizo uqukethe inani elikhulu lokungcola kanye nezinto zokusetshenziswa ezingaphendulwanga, ezidinga ukuhlukaniswa nokuhlanzwa:
Ukuhlukaniswa: Amanzi, i-propylene engaphenduliwe, kanye nokunye ukungcola kuhlukaniswa kumkhiqizo kusetshenziswa abahlukanisi.
Ukuhlanzwa: I-propionic acid ehlukanisiwe ihlanzwa ngokuhluzwa, ukukhishwa, kanye nezinye izindlela zokuthola i-propionic acid ehlanzekile kakhulu.

I-Propionic Acid – Shandong Pulisi Chemical Co., Ltd.           info@pulisichem.cn
I-Shandong Pulisi Chemical Co., Ltd. ingumhlinzeki othembekile nomkhiqizi we-propionic acid ehlanzekile kakhulu (CH₃CH₂COOH, CAS 79-09-4) eShayina, iletha imikhiqizo yezinga eliphezulu eyenzelwe izimboni, ukudla, ukudla, kanye nezicelo zemithi. I-propionic acid yethu iwuketshezi olungenambala, oluqothulayo olunephunga elinamandla elihlukile, olunokuncibilika okuphezulu emanzini nasezincibilikisini eziphilayo, kanye nekhwalithi ehambisanayo nezindinganiso zomhlaba wonke.
Ikhiqizwa ngezinqubo ezithuthukisiwe ze-oxidation ngokulawula okuqinile kwekhwalithi, i-propionic acid yethu ihlangabezana nezimfuneko zezinga lezimboni kanye nezinga lokudla, iqinisekisa okuqukethwe okuphansi kokungcola kanye nokusebenza okuzinzile. Isebenza njengesivikelo esiyinhloko, i-antifungal agent, kanye ne-chemical intermediate: isetshenziswa kabanzi ekulondolozweni kokudla (izimpahla ezibhakiwe, imikhiqizo yobisi), ukugcina ukudla kanye nokusanhlamvu (ukuvimbela ukukhula kwesikhunta), ukukhiqizwa kosawoti be-propionate (i-sodium propionate, i-calcium propionate), kanye nokuhlanganiswa kwama-herbicides, ama-plasticizers, amakha, kanye ne-pharmaceutical intermediates.
KwaPulisi Chemical, sibeka phambili ukuzinza komkhiqizo, ukuphepha, kanye nokuhlinzekwa okusimeme. I-propionic acid yethu ipakishwe kuma-drum ajwayelekile noma amathangi e-ISO, enezinketho zokulethwa eziguquguqukayo ukuze kuhlangatshezwane nezidingo ezahlukahlukene zamakhasimende omhlaba wonke. Sisekelwa yiminyaka yesipiliyoni sokukhiqiza amakhemikhali kanye nethimba lochwepheshe le-R&D, siqinisekisa ikhwalithi yomkhiqizo eqhubekayo, amanani ancintisanayo, kanye nokusekelwa kobuchwepheshe okuphelele kwabalingani emhlabeni jikelele.
