Acetate: Kev Tshuaj Xyuas Kev Hloov Pauv ntawm Kev Tsim Khoom thiab Kev Xav Tau hauv Lub Kaum Ob Hlis

Kev tsim cov acetate esters hauv kuv lub tebchaws thaum Lub Kaum Ob Hlis 2024 yog raws li nram 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 poob qis thaum Lub Kaum Ob Hlis. Ib kab ntawm ethyl acetate hauv Lunan tau ua haujlwm, thiab chav tsev Yongcheng thiab Huayi ob leeg tau kaw thaum lub hlis; qib kev ua haujlwm ntawm butyl acetate hauv South China qis, uas muaj kev cuam tshuam loj heev; kev tsim khoom ntawm sec-butyl acetate qis vim yog kev saib xyuas ntawm Dingying thiab Ruiyuan. Thaum Lub Kaum Ob Hlis, kev tsim khoom yuav nce thiab poob, nrog ethyl acetate nce thiab butyl thiab sec-butyl acetate poob qis.

Thaum Lub Kaum Ob Hlis 2024, lub peev xwm tsim cov acetic acid esters hauv tebchaws tau poob qis. Lub peev xwm tsim khoom nruab nrab txhua hli ntawm ethyl acetate yog 54.23%, poob 2.59 feem pua ​​ntawm lub hli dhau los. Cov kab hauv sab qab teb Shandong, Sopo tau txo nws cov khoom thauj, thiab cov nroj tsuag Huayi thiab Henan tau kaw; lub peev xwm tsim khoom nruab nrab txhua hli ntawm butyl acetate yog 59.68%, poob 2.63 feem pua ​​ntawm lub hli dhau los, thiab lub peev xwm tsim khoom hauv sab qab teb Suav teb qis; lub peev xwm tsim khoom nruab nrab txhua hli ntawm sec-butyl acetate yog 60.68%, poob 10.23 feem pua ​​ntawm lub hli dhau los, thiab Dingying raug cuam tshuam loj heev los ntawm kev saib xyuas.

Kev Xav Tau: Qhov kev xav tau acetate thaum lub Kaum Ob Hlis yog qhov txaus siab. Rau ethyl acetate, cov tub luam tau yuav cov khoom lag luam ntawm tus nqi qis thaum lub hli, thiab qhov chaw ua lag luam hauv khw zoo. Cov khoom muag hauv sab qab teb Shandong tau poob qis mus rau qib qis, thiab cov tuam txhab lag luam hauv Sab Hnub Tuaj Tuam Tshoj feem ntau tau xa cov khoom xa tawm, tsis muaj kev nyuaj siab rau kev xa khoom. Rau butyl acetate thiab sec-butyl acetate, kev ua lag luam ceev faj txog kev thov tsis ruaj khov, thiab qee cov khoom lag luam ua ntej Lub Caij Nplooj Ntoos Hlav pib, tab sis lawv feem ntau tos tus nqi qis dua thiab ua haujlwm ntawm tus nqi qis. Cov neeg tuav lag luam pauv tus nqi rau qhov ntim, thiab qhov kev xav tau tau zoo dua ib ntus. Muaj kev sib tham txog kev xa tawm rau sec-butyl acetate, thiab tag nrho kev lag luam zoo dua li ntawm butyl acetate.
