3. Inkqubo yeMethanol Carbonalylation
I-Methanol carbonylation yindlela entsha yokuvelisa i-propionic acid. Isebenzisa i-methanol njengezinto eziluhlaza, i-reaction yenzeka xa kukho i-catalyst yokwenza inkqubo ye-carbonyl ephakathi esekwe kwi-methanol, ethi emva koko i-oxidized ivelise i-propionic acid.
4. Inkqubo yokuOxidation yePropylene
1. Ukulungiswa kwezinto eziluhlaza
Izinto ezisetyenziswa ekucociseni ipropylene ziquka ipropylene, umoya, namanzi. Ipropylene ifunyanwa kwiindawo zokucocisa okanye kwizityalo eziqhekekayo, ngelixa umoya uvela kwiiyunithi zokwahlula umoya.
2. Inkqubo yokusabela
Ukufudumeza: Ipropylene nomoya zifudunyezwa ngokwahlukeneyo kumaqondo obushushu afanelekileyo ukuqinisekisa ukuba impendulo iqhubeka kakuhle.
I-Catalytic Reaction: I-propylene eshushu kunye nomoya ziyaxutywa kwaye ziphenduleke xa kukho i-catalyst. Eli nyathelo lenzeka phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo, ngesiqhelo kwi-250–350°C kunye ne-1–3 MPa.
Ukupholisa: Imveliso yokusabela ipholiswa kubushushu begumbi nge-cooler ukuze iqhubeke nokucutshungulwa.
3. Ukwahlulwa kunye nokuhlanjululwa
Emva kwempendulo, imveliso iqulethe ubuninzi bokungcola kunye nezinto ezingafunekiyo, ezifuna ukwahlukana nokucocwa:
Ukwahlulwa: Amanzi, ipropylene engaphendulwanga, kunye nezinye izinto ezingcolileyo zahlulwa kwimveliso kusetyenziswa izixhobo zokwahlulahlula.
Ukucocwa: I-propionic acid ehlukanisiweyo icocwa nge-distillation, i-extract, kunye nezinye iindlela zokufumana i-propionic acid ecocekileyo kakhulu.

I-Propionic Acid – iShandong Pulisi Chemical Co., Ltd.           info@pulisichem.cn
I-Shandong Pulisi Chemical Co., Ltd. ngumthengisi othembekileyo kunye nomvelisi we-propionic acid ecocekileyo kakhulu (CH₃CH₂COOH, CAS 79-09-4) eTshayina, ihambisa iimveliso ezikumgangatho ophezulu ezenzelwe ukusetyenziswa kwimizi-mveliso, ukutya, ukutya, kunye namayeza. I-propionic acid yethu lulwelo olungenambala, olurhabaxa olunevumba elibi, olunokunyibilika okuphezulu emanzini nakwizinto eziphilayo, kunye nomgangatho ohambelanayo ohambelana nemigangatho yamazwe ngamazwe.
Iveliswe ngeenkqubo eziphambili ze-oxidation ezinolawulo oluqinileyo lomgangatho, i-propionic acid yethu ihlangabezana neemfuno zezinga loshishino kunye nezinga lokutya, iqinisekisa umxholo ophantsi wokungcola kunye nokusebenza okuzinzileyo. Isebenza njengesithinteli esibalulekileyo, iarhente yokubola, kunye ne-chemical intermediate: isetyenziswa kakhulu ekugcineni ukutya (iimpahla ezibhakiweyo, iimveliso zobisi), ukugcina ukutya kunye neenkozo (ukuthintela ukukhula kwesikhunta), ukuvelisa iityuwa ze-propionate (i-sodium propionate, i-calcium propionate), kunye nokuhlanganiswa kwe-herbicides, ii-plasticizers, iziqholo, kunye ne-pharmaceutical intermediates.
Apha ePulisi Chemical, sibeka phambili uzinzo lwemveliso, ukhuseleko, kunye nobonelelo oluzinzileyo. I-propionic acid yethu ipakishwe kwiidrama eziqhelekileyo okanye kwiitanki ze-ISO, kunye neendlela zokuhambisa eziguquguqukayo ukuhlangabezana neemfuno ezahlukeneyo zabathengi behlabathi. Sixhaswa ngamava eminyaka yokuvelisa iikhemikhali kunye neqela lobuchwephesha le-R&D, siqinisekisa umgangatho wemveliso ohambelanayo, amaxabiso akhuphisanayo, kunye nenkxaso yobugcisa epheleleyo kumaqabane kwihlabathi liphela.
