1. Butadiene
Lub khw muag khoom muaj kev kub ntxhov, thiab cov nqi tseem nce ntxiv
Tus nqi khoom ntawm butadiene tau nce siab tsis ntev los no, qhov chaw ua lag luam hauv khw muaj kev ua haujlwm zoo, thiab qhov xwm txheej tsis txaus khoom tseem txuas ntxiv mus rau lub sijhawm luv luv, thiab kev ua lag luam muaj zog. Txawm li cas los xij, nrog rau kev nce ntxiv ntawm qee cov khoom siv thiab kev siv lub peev xwm tsim khoom tshiab, muaj kev cia siab tias yuav muaj kev nce ntxiv ntawm kev muab khoom hauv kev ua lag luam yav tom ntej, thiab kev ua lag luam butadiene yuav ruaj khov tab sis tsis muaj zog.
2. Methanol
Cov yam zoo txhawb nqa kev ua lag luam kom hloov pauv siab dua
Lub 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 xa tuaj yuav txo qis, thiab cov khoom muag methanol ntawm chaw nres nkoj tau maj mam nkag mus rau hauv txoj kev tshem tawm. Thaum cov khoom muag tsawg, cov tuam txhab feem ntau tuav tus nqi kom xa khoom; kev thov downstream tswj hwm qhov kev cia siab ntawm kev loj hlob ntxiv. Nws xav tias lub khw muag khoom methanol hauv tebchaws yuav muaj zog thiab tsis ruaj khov hauv lub sijhawm luv luv.
3. Methylene Chloride
Kev ua lag luam ntawm kev muab khoom thiab kev thov poob qis
Tus nqi ua lag luam ntawm dichloromethane tau poob qis tsis ntev los no. Kev ua haujlwm ntawm kev lag luam tau tswj hwm thaum lub lim tiam, thiab sab kev thov tau tswj hwm kev yuav khoom ruaj khov. Kev ua lag luam hauv khw tau qaug zog, thiab cov khoom lag luam ntawm cov tuam txhab tau nce ntxiv. Thaum kawg ntawm lub xyoo los txog, tsis muaj cov khoom lag luam loj, thiab kev tos-thiab-saib kev xav muaj zog. Nws xav tias kev ua lag luam dichloromethane yuav ua haujlwm tsis muaj zog thiab ruaj khov hauv lub sijhawm luv luv.
4. Isooctyl cawv
Cov hauv paus tsis muaj zog thiab cov nqi poob qis
Tus nqi ntawm isooctanol tau poob qis tsis ntev los no. Cov lag luam isooctanol tseem ceeb muaj kev ua haujlwm ruaj khov, tag nrho cov khoom siv ntawm isooctanol txaus, thiab kev ua lag luam nyob rau lub caij tsis muaj, thiab qhov kev thov qis dua tsis txaus. Nws xav tias tus nqi ntawm isooctanol yuav hloov pauv thiab poob qis hauv lub sijhawm luv luv.
