1. Butadiene
Kev lag luam huab cua yog active, thiab cov nqi txuas ntxiv
Tus nqi khoom ntawm butadiene tau raug tsa tsis ntev los no, kev lag luam kev lag luam huab cua kuj tseem muaj zog, thiab cov khoom lag luam tsis txaus tseem nyob rau lub sijhawm luv luv, thiab kev lag luam muaj zog. Txawm li cas los xij, nrog rau kev nce ntawm qee cov khoom siv thiab kev ua haujlwm ntawm kev tsim khoom tshiab, muaj kev cia siab ntawm kev nce hauv cov khoom lag luam yav tom ntej, thiab kev ua lag luam butadiene yuav tsum ruaj khov tab sis tsis muaj zog.
2. Methanol
Cov yam ntxwv zoo txhawb kev lag luam kom hloov pauv siab dua
Kev lag luam methanol tau nce siab tsis ntev los no. Vim muaj kev hloov pauv hauv cov chaw tseem ceeb hauv Middle East, qhov ntim ntawm methanol yuav tsum txo qis, thiab cov khoom muag methanol ntawm qhov chaw nres nkoj tau maj mam nkag mus rau hauv destocking channel. Raws li cov khoom muag qis, cov tuam txhab feem ntau tuav cov nqi xa khoom; downstream kev thov tswj qhov kev cia siab ntawm kev loj hlob ntxiv. Nws cia siab tias kev lag luam methanol hauv tsev yuav muaj zog thiab tsis muaj zog nyob rau lub sijhawm luv.
3. Methylene Chloride
Kev muab khoom thiab xav tau kev ua lag luam kev lag luam poob qis
Tus nqi lag luam ntawm dichloromethane tau poob tsis ntev los no. Kev lag luam kev lag luam kev lag luam tau khaws cia nyob rau lub lim tiam, thiab cov neeg thov kev xav tau tswj xyuas kev yuav khoom nruj. Kev lag luam kev lag luam huab cua tsis muaj zog, thiab cov khoom lag luam tau nce ntxiv. Raws li qhov kawg ntawm lub xyoo los txog, tsis muaj cov khoom lag luam loj, thiab kev tos-thiab-saib kev xav tau muaj zog. Nws cia siab tias kev lag luam dichloromethane yuav ua haujlwm tsis muaj zog thiab ruaj khov nyob rau lub sijhawm luv.
4. Isooctyl cawv
Cov hauv paus tsis muaj zog thiab poob nqi
Tus nqi ntawm isooctanol tau poob tsis ntev los no. Lub tuam txhab isooctanol tseem ceeb muaj cov cuab yeej siv ruaj khov ua haujlwm, tag nrho cov khoom siv ntawm isooctanol txaus, thiab kev ua lag luam nyob rau lub caij tawm, thiab qhov kev thov qis qis tsis txaus. Nws cia siab tias tus nqi ntawm isooctanol yuav hloov pauv thiab poob rau lub sijhawm luv.
