Sabata yatha, msika wapabanja wa acetic asidi udasiya kugwa ndi mitengo idakwera. Kukhazikika kosayembekezereka kwa Yankhong lunan ndi jiangsu SUPU Mayupu ku China kwayambitsa kuchepa kwa msika. Pambuyo pake, chipangizocho pang'onopang'ono chidachira ndikuchepetsa chilipo. Kupezeka kwa acetic acid ndi kolimba, ndipo mtengo wa acetic acid yawonjezera. Kuphatikiza apo, mitengo yamalonda kumpoto chakumadzulo kwachulukirachulukira, pomwe zolemba zopangira m'magawo ena zachulukanso, zomwe zimapangitsa kuti ntchito ikhale yolimba sabata yatha.

Pofika mu Ogasiti 6, mtengo wa Acetic acid ku East China anali 3150.00 Yuan / Retior /67 Yuan pa Julayi 3100 pamwezi pamwezi. Kuyambira kwa Ogasiti 4th, mitengo yamasika ya acetic acid m'madera osiyanasiyana sabata ino ndi motere:

Mphepo yamkuntho yothira misika ya methanol imasintha kwambiri. Pofika pa Julayi 6th, mtengo wapakatikati pamsika wapabanja uli 235 yuan / ton. Poyerekeza ndi mtengo wa 2280 Yuan / Ton pa Julayi 31st, kuwonjezeka kwathunthu kwa 3.07%. Chithandizo chachikulu cha kukwera kwa mtengo wa sabata chatha chinali kufunikira. Chipangizo chachikulu cha mto. Kuphatikiza apo, zopindulitsa za macroeconocomic zathandizanso kukhala ndi gawo lolimbikitsa. Nthawi yomweyo, kufufuza ku ponter kwachepa kwambiri, ndipo msika wa methanol ukuyenda pang'onopang'ono. Potengera mtengo, mitengo yagwa, thandizo lafooka, kufunikira ndi zabwino, ndipo mitengo ya methanol yasintha ndikusintha.

Zophatikizira zamagetsi am'munsi a arhydride. Pofika pa 8 Ogasiti 6 Mtengo wa kumtunda acetic acid yawonjezeka, ndipo mphamvu yoyendetsa yochulukitsa ya acetic terhydride yawonjezeka. Komabe, kutsikira kumakumanako kumakhala kotsika mtengo, kumafuna kuti izi zikhale zosakwanira, zomwe zimachitika pamsika ndizochepa, ndipo mtengo wa acerhydride woyamba umatuluka kenako nkugwa.

Pakadali pano, pakukonzanso pang'onopang'ono zida zoimikapo magalimoto pamsika, kulibe kukakamiza pamsika, ndipo mbali yofunikira yatsata bwino. Opanga acetic acid ali ndi chiyembekezo chokhudza izi ndipo palibe kukakamiza pa kufufuza fakitale. Kuthandizidwa ndi Nkhani Zabwino, Zikuyembekezeredwa kuti msika wa acetic asidi upitilize kugwira ntchito mwamphamvu mtsogolo.
