3. Ts'ebetso ea Methanol Carbonalylation
Khabone ya methanol ke mokhoa o hlahellang wa ho hlahisa propionic acid. Ka ho sebedisa methanol e le thepa e tala, karabelo e etsahala boteng ba catalyst ho theha sistimi ya carbonyl e thehilweng ho methanol, ebe e oxidized ho hlahisa propionic acid.
4. Ts'ebetso ea ho Oxidation ea Propylene
1. Tokisetso ea Lisebelisoa tse Tala
Lisebelisoa tse tala tsa ho oxidation ea propylene li kenyelletsa propylene, moea le metsi. Propylene e fumanoa libakeng tsa ho hloekisa kapa limela tse petsohang, ha moea o tsoa liyuniti tsa karohano ea moea.
2. Ts'ebetso ea Karabelo
Ho futhumatsa: Propylene le moea li futhumatsoa ka thoko mochesong o loketseng ho netefatsa hore karabelo e tsoela pele hantle.
Karabelo ea Catalytic: Propylene e seng e chesitsoe le moea lia kopanngoa 'me lia arajoa ha ho na le catalyst. Mohato ona o etsahala tlas'a mocheso o phahameng le maemo a khatello, hangata ho 250–350°C le 1–3 MPa.
Ho Pholisa: Sehlahisoa sa karabelo se phodiswa mochesong wa kamore ka sehatsetsi bakeng sa ts'ebetso e eketsehileng.
3. Karohano le Tlhoekiso
Kamora karabelo, sehlahisoa se na le litšila tse ngata le thepa e tala e sa arajoang, e hlokang karohano le tlhoekiso:
Karohano: Metsi, propylene e sa arajoang, le litšila tse ling li aroloa ho sehlahisoa ho sebelisoa li-aparthor.
Tlhoekiso: Asiti ea propionic e arotsoeng e hloekisoa ka ho qhibilihisa, ho ntša le mekhoa e meng ho fumana asiti ea propionic e hloekileng haholo.

Asiti ea Propionic – Shandong Pulisi Chemical Co., Ltd.           info@pulisichem.cn
Shandong Pulisi Chemical Co., Ltd. ke mofani le moetsi ea tšepahalang oa propionic acid e hloekileng haholo (CH₃CH₂COOH, CAS 79-09-4) Chaena, e fana ka lihlahisoa tsa boleng bo holimo tse etselitsoeng liindasteri, lijo, lijo le meriana. Asiti ea rona ea propionic ke mokelikeli o se nang 'mala, o senyang o nang le monko o ikhethang o bohale, o nang le ho qhibiliha ho hoholo metsing le li-solvents tsa tlhaho, 'me boleng bo tsitsitseng bo lumellana le maemo a machaba.
E hlahisitsoe ka mekhoa e tsoetseng pele ea oxidation ka taolo e tiileng ea boleng, propionic acid ea rona e fihlela litlhoko tsa maemo a indasteri le a lijo, e netefatsa hore ho na le litšila tse fokolang le ts'ebetso e tsitsitseng. E sebetsa e le sesebelisoa sa bohlokoa sa ho boloka, moemeli oa antifungal, le sesebelisoa sa lik'hemik'hale: se sebelisoa haholo ho bolokeng lijo (lihlahisoa tse besitsoeng, lihlahisoa tsa lebese), polokelo ea lijo le lijo-thollo (ho thibela kholo ea hlobo), tlhahiso ea letsoai la propionate (sodium propionate, calcium propionate), le tlhahiso ea litlama, li-plasticizer, monko o monate le metsoako ea meriana.
Ho Pulisi Chemical, re beha pele botsitso ba sehlahisoa, polokeho le phepelo e tsitsitseng. Asiti ea rona ea propionic e pakiloe ka har'a meropa e tloaelehileng kapa litanka tsa ISO, ka likhetho tse tenyetsehang tsa ho fana ho fihlela litlhoko tse fapaneng tsa bareki ba lefats'e ka bophara. Re tšehelitsoe ke boiphihlelo ba lilemo tsa tlhahiso ea lik'hemik'hale le sehlopha sa litsebi sa R&D, re netefatsa boleng bo tsitsitseng ba sehlahisoa, litheko tse hlōlisanang, le tšehetso e felletseng ea tekheniki bakeng sa balekane lefatšeng ka bophara.
