3. Cov txheej txheem carbonylation methanol
Methanol carbonylation yog ib txoj kev tshiab rau kev tsim cov propionic acid. Siv methanol ua cov khoom siv raw, qhov kev tshuaj tiv thaiv tshwm sim nyob rau hauv qhov muaj cov catalyst los tsim cov methanol-based carbonyl intermediate system, uas tom qab ntawd oxidized los tsim cov propionic acid.
4. Cov txheej txheem oxidation propylene
1. Kev Npaj Khoom Siv Raw
Cov khoom siv raw rau propylene oxidation suav nrog propylene, cua, thiab dej. Propylene tau los ntawm cov chaw ua roj lossis cov chaw tawg, thaum huab cua tau los ntawm cov chaw sib cais cua.
2. Cov txheej txheem tshuaj tiv thaiv
Kev Ua Ntej: Propylene thiab cua raug preheated sib cais rau qhov kub thiab txias kom ntseeg tau tias cov tshuaj tiv thaiv ua haujlwm tau zoo.
Kev Ua Tshuaj Tiv Thaiv Kab Mob: Cov propylene thiab cua uas tau ua ntej lawm tau sib xyaw thiab ua tshuaj tiv thaiv nyob rau hauv qhov muaj cov tshuaj tiv thaiv kab mob. Cov kauj ruam no tshwm sim nyob rau hauv qhov kub thiab txias siab thiab siab, feem ntau ntawm 250–350°C thiab 1–3 MPa.
Kev Txias: Cov khoom ua haujlwm raug txias rau chav tsev kub ntawm lub tshuab txias rau kev ua tiav ntxiv.
3. Kev Sib Cais thiab Kev Ua Kom Huv Si
Tom qab ua cov tshuaj tiv thaiv, cov khoom muaj cov khoom tsis huv thiab cov khoom siv raw tsis tau ua haujlwm, xav tau kev sib cais thiab kev ntxuav:
Kev Sib Cais: Dej, propylene tsis muaj zog, thiab lwm yam tsis huv raug sib cais los ntawm cov khoom siv cov khoom sib cais.
Kev Ntxuav: Cov propionic acid sib cais yog ntxuav los ntawm kev distillation, extraction, thiab lwm txoj hauv kev kom tau txais cov tshuaj propionic acid uas muaj cov khoom huv siab.
Propionic Acid - Shandong Pulisi Chemical Co., Ltd. info@pulisichem.cn
Shandong Pulisi Chemical Co., Ltd. yog ib lub tuam txhab tsim khoom thiab muag khoom ntawm cov tshuaj propionic acid (CH₃CH₂COOH, CAS 79-09-4) uas muaj txiaj ntsig zoo hauv Suav teb, thiab muab cov khoom zoo tshaj plaws rau kev siv hauv kev lag luam, khoom noj, pub tsiaj, thiab tshuaj. Peb cov tshuaj propionic acid yog cov kua tsis muaj xim, muaj zog corrosive nrog cov ntxhiab tsw qab, muaj peev xwm yaj tau zoo hauv dej thiab cov kuab tshuaj organic, thiab zoo sib xws raws li cov qauv thoob ntiaj teb.
Ua los ntawm cov txheej txheem oxidation siab heev nrog kev tswj hwm zoo nruj, peb cov propionic acid ua tau raws li qib kev lag luam thiab qib zaub mov, kom ntseeg tau tias cov ntsiab lus tsis muaj kuab paug tsawg thiab kev ua haujlwm ruaj khov. Nws ua haujlwm ua tus neeg khaws cia tseem ceeb, tus neeg sawv cev antifungal, thiab tshuaj nruab nrab: siv dav hauv kev khaws cia zaub mov (khoom ci, khoom noj mis), pub thiab khaws cia nplej (txwv tsis pub pwm loj hlob), tsim cov ntsev propionate (sodium propionate, calcium propionate), thiab kev tsim cov tshuaj tua kab, cov yas, cov tshuaj tsw qab, thiab cov tshuaj nruab nrab.
Ntawm Pulisi Chemical, peb muab qhov tseem ceeb rau kev ruaj khov ntawm cov khoom, kev nyab xeeb, thiab kev muab khoom siv tau ntev. Peb cov propionic acid tau ntim rau hauv cov thoob thoob ntiaj teb lossis cov thoob ISO, nrog rau kev xaiv xa khoom yooj ywm kom tau raws li cov neeg siv khoom thoob ntiaj teb cov kev xav tau sib txawv. Txhawb nqa los ntawm ntau xyoo ntawm kev paub txog kev tsim tshuaj lom neeg thiab pab pawg R & D tshaj lij, peb lav qhov zoo ntawm cov khoom, tus nqi sib tw, thiab kev txhawb nqa kev txawj ntse rau cov neeg koom tes thoob ntiaj teb.
