Acetate: Kev tshuaj xyuas kev tsim khoom thiab kev thov hloov pauv hauv lub Kaum Ob Hlis

Kev tsim cov acetate esters hauv kuv lub tebchaws thaum Lub Kaum Ob Hlis 2024 yog raws li hauv qab no: 180,700 tons ntawm ethyl acetate ib hlis; 60,600 tons ntawm butyl acetate; thiab 34,600 tons ntawm sec-butyl acetate. Kev tsim khoom tau poob rau lub Kaum Ob Hlis. Ib kab ntawm ethyl acetate hauv Lunan tau ua haujlwm, thiab chav tsev Yongcheng thiab Huayi ob leeg raug kaw thaum lub hli; qib kev ua haujlwm ntawm butyl acetate nyob rau sab qab teb Tuam Tshoj tau qis, uas muaj kev cuam tshuam loj heev; kev tsim cov sec-butyl acetate tsawg vim yog kev saib xyuas ntawm Dingying thiab Ruiyuan. Thaum lub Kaum Ob Hlis, kev tsim khoom yuav tsum nce thiab poob, nrog ethyl acetate nce thiab butyl thiab sec-butyl acetate poob qis.

Nyob rau lub Kaum Ob Hlis 2024, cov khoom siv hluav taws xob hauv tsev acetic acid esters muaj peev xwm poob qis. Qhov nruab nrab txhua hli tsim muaj peev xwm ntawm ethyl acetate yog 54.23%, nqis 2.59 feem pua ​​​​ntawm lub hli dhau los. Txoj kab nyob rau yav qab teb Shandong, Sopo txo ​​nws cov load, thiab Huayi thiab Henan nroj tsuag raug kaw; qhov nruab nrab txhua hli muaj peev xwm ntawm butyl acetate yog 59.68%, nqis 2.63 feem pua ​​​​ntawm cov ntsiab lus ntawm lub hli dhau los, thiab lub peev xwm ntau lawm nyob rau yav qab teb Tuam Tshoj yog tsawg; qhov nruab nrab txhua hli tsim muaj peev xwm ntawm sec-butyl acetate yog 60.68%, nqis 10.23 feem pua ​​​​ntawm lub hli dhau los, thiab Dingying tau cuam tshuam zoo heev los ntawm kev saib xyuas.

Kev thov: Qhov kev thov rau acetate thaum lub Kaum Ob Hlis tau txais. Rau ethyl acetate, cov tub lag luam yuav cov khoom lag luam ntawm tus nqi qis thaum lub hli, thiab kev lag luam kev lag luam tau zoo. Cov khoom muag nyob rau yav qab teb Shandong tau poob mus rau theem qis, thiab cov tuam txhab lag luam nyob rau sab hnub tuaj Suav teb feem ntau xa cov khoom xa tawm, tsis muaj lub zog rau nkoj. Rau butyl acetate thiab sec-butyl acetate, kev ua lag luam tau ceev faj txog kev xav tau nruj, thiab qee cov khoom lag luam ua ntej Lub Caij Nplooj Ntoos Hlav tau pib, tab sis lawv feem ntau tos kom txo nqi thiab ua haujlwm ntawm tus nqi qis. Cov neeg tuav lag luam pauv tus nqi rau ntim, thiab kev thov tau zoo tuaj ib ntus. Muaj kev sib tham txog kev xa tawm rau sec-butyl acetate, thiab kev lag luam tag nrho yog zoo dua li ntawm butyl acetate.
