Txog li 3 hnub, kev ua lag luam acetic acid hauv tsev ruaj khov thiab khov kho. Tag nrho, cov nqi ntawm thoob plaws 2 hnub muaj zog dua li tus nqi nruab nrab nce lub lim tiam dhau los. Tag nrho cov khoom siv ntawm kev ua lag luam tseem nruj, tus nqi ntawm cov lag luam muaj rau kev muag khoom tseem qis vim muaj ntau tus lej xaj, qhov kev thov downstream ruaj khov, tus nqi ua lag luam muaj zog.

Thaum Lub Kaum Ib Hlis 3, tus nqi siv hauv kev lag luam Jiangsu yog 2,700-2,800 yuan / ton, tsis hloov pauv ntawm qhov siab tshaj plaws yav dhau los ntawm 2,700-2,800 yuan / ton thaum Lub Kaum Ib Hlis 2. Tus nqi siv hauv kev lag luam sab qab teb Suav teb yog 2750-2800 yuan / ton, uas yog tib yam li tus nqi siab dhau los (Lub Ob Hlis 17) ntawm lub xyoo no.

Tam sim no, lub Hoobkas ua kua qaub acetic hauv tsev pib ua haujlwm tau zoo. Lub Hoobkas ua haujlwm tau zoo li qub, thiab tus nqi ua haujlwm tau tswj hwm ntawm qib siab ntawm 95%. Tus nqi ua haujlwm siab tsis tau ua rau muaj kev nyuaj siab rau sab kev muab khoom. Lub tuam txhab cov khoom xa tuaj tau mus zoo thiab cov khoom muag tseem nyob rau qib qis.

Thaum kawg ntawm lub Kaum Hli, cov khoom lag luam glacial acetic acid hauv tebchaws tseem poob qis. Sab Hnub Tuaj Suav teb, cov khoom muag tau poob me ntsis, qhov xwm txheej xa khoom lag luam zoo. Hauv nruab nrab Suav teb, cov khoom muag tau pib poob qis, thiab qhov poob loj tshaj plaws, qee lub tuam txhab cov khoom muag tsis txaus, muag tsawg. Thaj av Jin-ji, cov khoom muag tau pib nce, tab sis kev xa khoom tag nrho kuj nrawm dua. Thaj av Shandong, cov khoom muag tseem poob qis, muag tau yooj yim. Cov khoom lag luam hauv sab qaum teb sab hnub poob Suav teb tseem poob qis. Cov khoom muag hauv sab qab teb sab hnub poob tsis hloov pauv ntawm lub lim tiam dhau los.

Tag nrho cov khoom muag hauv tsev tau poob qis 12.44 feem pua ​​piv rau lub Kaum Hli 19.

Txij li thaum Lub Kaum Ib Hlis 3, kev lag luam khoom lag luam acetic acid downstream tau ruaj khov. Kev lag luam ethyl acetate tau ua haujlwm ruaj khov thiab tau nce siab thoob plaws theem thaum ntxov. Tus nqi tam sim no nyob rau theem siab, cov khoom lag luam tsis muaj ntau, tab sis lub zog tsav ntawm tus nqi tiaj tus tsis txaus, thiab cov roj yuav khoom tsis muaj zog ua rau cov txheej txheem nce qeeb. Kev lag luam butyl acetate ruaj khov thiab mos, qhov chaw ntawm cov khoom siv raw tag nrho tau poob qis, kev xa khoom ntawm cov tuam txhab yog qhov ncaj ncees, huab cua txais downstream tsis zoo, kev lag luam tag nrho tsis muaj zog. Kev lag luam acetic acid butyl ester ruaj khov, sab kev muab khoom txaus, lub siab dav dav ntawm downstream, thawb kom tsis muaj zog. Kev lag luam vinyl acetate ruaj khov, yog tias muaj kev txhawb nqa tus nqi muaj zog, kev muab khoom tsawg, kev lag luam khiav muaj zog. Kev lag luam Vinegar anhydride ruaj khov pom kev nce siab, cuam tshuam los ntawm kev kho dua tshiab cov khoom siv yankuang, kev muab khoom lag luam tsis ntau, huab cua downstream yog qhov ncaj ncees, kev lag luam muaj zog.

Nyob rau lub sijhawm tom qab, hais txog kev muab khoom, txawm hais tias cov chaw tsim khoom tswj hwm tus nqi ua haujlwm siab, cov khoom ntws zoo, thiab kev nyuaj siab ntawm cov khoom lag luam tsis muaj. Nws xav tias sab kev muab khoom hauv lub sijhawm tom qab yuav tseem zoo. Ntawm sab kev thov, tom qab "Xyoo Kaum Ib Hlis Nyiaj", kev xav yuav khoom ntawm cov lag luam downstream tseem ruaj khov, thiab kev thov txawv teb chaws nce siab, thiab sab xa khoom tuaj yeem pom kev lag luam rov qab los. Kev lag luam acetic acid xav tias yuav khiav zoo heev yav tom ntej.
