Tus nqi sib txawv ntawm acetic acid txuas ntxiv poob rau lub Rau Hli, nrog tus nqi nruab nrab ntawm 3216.67 yuan / ton thaum pib ntawm lub hli thiab 2883.33 yuan / ton thaum kawg ntawm lub hli. Tus nqi txo los ntawm 10.36% thaum lub hli, ib xyoos ib zaug txo ntawm 30.52%.

Tus nqi sib txawv ntawm acetic acid tau txuas ntxiv poob rau lub hlis no, thiab kev lag luam tsis muaj zog. Txawm hais tias qee qhov kev lag luam hauv tsev tau kho qhov loj rau cov nroj tsuag acetic acid, uas ua rau txo qis hauv cov khoom lag luam, kev lag luam qis qis, nrog kev siv tsis tshua muaj peev xwm, tsis txaus ntawm acetic acid, thiab kev lag luam lag luam tsawg. Qhov no tau ua rau kev muag khoom tsis zoo ntawm cov lag luam, nce hauv qee cov khoom muag, kev xav tsis zoo ntawm kev ua lag luam, thiab tsis muaj cov txiaj ntsig zoo, ua rau muaj kev hloov pauv tsis tu ncua ntawm kev ua lag luam acetic acid.
Raws li qhov kawg ntawm lub hli, cov ntsiab lus ntawm acetic acid ua lag luam nyob rau ntau thaj tsam ntawm Tuam Tshoj nyob rau lub Rau Hli yog raws li hauv qab no:

Piv nrog rau tus nqi ntawm 2161.67 yuan / ton rau lub Rau Hli 1st, cov khoom siv raw khoom methanol ua lag luam hloov pauv loj, nrog rau tus nqi nruab nrab hauv tsev lag luam ntawm 2180.00 yuan / ton thaum kawg ntawm lub hli, tag nrho nce ntawm 0.85%. Tus nqi ntawm cov thee nyoos tsis muaj zog thiab hloov pauv, nrog kev txhawb nqa tus nqi tsawg. Tag nrho cov khoom lag luam sib raug zoo ntawm methanol ntawm cov khoom siv yog siab, thiab kev lag luam kev ntseeg siab tsis txaus. Cov kev xav tau hauv qab yog qhov tsis muaj zog, thiab kev ua raws li kev yuav khoom tsis txaus. Raws li cov khoom siv thiab xav tau kev ua si, tus nqi ntau ntawm methanol fluctuates.

Kev lag luam downstream acetic anhydride txuas ntxiv poob rau lub Rau Hli, nrog rau ib hlis xaus lus ntawm 5000.00 yuan / tuj, 7.19% txo txij thaum pib ntawm lub hli mus rau 5387.50 yuan / tuj. Tus nqi ntawm acetic acid raw cov ntaub ntawv tau txo qis, tus nqi txhawb rau acetic anhydride tsis muaj zog, acetic anhydride cov tuam txhab ua haujlwm ib txwm ua, cov khoom lag luam txaus txaus, cov kev xav tau qis qis, thiab kev lag luam kev lag luam cua txias. Txhawm rau txhawb kev txo cov nqi xa khoom, kev lag luam acetic anhydride ua haujlwm tsis muaj zog.

Kev lag luam hauv zej zog ntseeg tias cov khoom muag ntawm cov lag luam acetic acid tseem nyob rau theem qis, thiab cov tuam txhab lag luam feem ntau ua haujlwm thauj khoom, nrog kev xav tau tsis zoo. Kev siv hluav taws xob qis qis qis qis qis, nrog rau kev yuav khoom tsis zoo txaus siab. Downstream acetic acid kev txhawb nqa tsis muaj zog, kev ua lag luam tsis muaj txiaj ntsig zoo, thiab kev xa khoom thiab kev thov tsis muaj zog. Nws cia siab tias kev lag luam acetic acid yuav ua haujlwm tsis muaj zog hauv kev ua lag luam pom, thiab kev hloov pauv ntawm cov khoom siv yuav tau txais kev saib xyuas tshwj xeeb.
