1.Kusanthula kwamtundaasidi asidimayendedwe a msika

Mtengo wa acetic acid kumayambiriro kwa mwezi unali 3235.00 yuan / tani, ndipo mtengo kumapeto kwa mwezi unali 3230.00 yuan / tani, kuwonjezeka kwa 1.62%, ndipo mtengo unali 63.91% wotsika kuposa chaka chatha.

Mu Seputembala, msika wa acetic acid udalamulidwa ndi mitundu yosiyanasiyana ya oscillation, pomwe mitengo idatsika isanakwere. Mu theka loyamba la chaka, msika wa asidi acetic unali wophatikizana, wokhala ndi zokwanira zokwanira, kufunikira kochepa kwapansi pamtsinje, kufooka kwa msika ndi kufunikira, mitengo ya acetic acid inasinthasintha; mu theka lachiwiri la chaka, msika wa asidi acetic unali wofooka ndi wotsika, makamaka chifukwa mabizinesi osamalira acetic acid adayambanso kugwira ntchito bwino, kupezeka kwa msika kunali kokwanira, kugula kwapansi kwa mtsinje kunapitirizabe kufooka, kupereka kunali kolimba ndi kufooka, mitengo ya acetic inapitirizabe kutsika; Pakutha kwa mweziwo, tchuthi cha Tsiku Ladziko Lonse chinali kuyandikira, kufunikira kwa masitomu akutsika kumawonjezeka, ndipo mabizinesi anali ndi cholinga chokweza mitengo. Kumapeto kwa mweziwo, kuperekedwako kunakwera, kutsatiridwa ndi kuwonjezeka kwa mtengo wa methanol kumtunda, chithandizo cha zinthu zopangira ndi chabwino, kumapeto kwa mwezi mitengo ya acetic acid idakwera mpaka kumayambiriro kwa mwezi.

2. ethyl acetate kusanthula kwa msika

Mu Seputembala, ethyl acetate yapakhomo ikadali yofooka, msika udakalipobe. Malinga ndi ziwerengero za Business News Service, kuchepa kwa mwezi uno kunali 0.43%, ndipo kumapeto kwa mweziwo, mtengo wamsika wa ethyl acetate unali 6700-7000 yuan / ton.

Mwezi uno, mtengo mbali ya ethyl acetate si zabwino kwambiri, asidi asidi ambiri a mwezi oscillating kutsika, sabata yatha ya September rebounded, kutsogolera kwa nthawi yaifupi ya ethyl acetate mmwamba, kutha kwa mwezi sangathe kupirira, mitengo akadali sanabwerere ku chiyambi cha mlingo. Panali kusintha pang'ono kumbali yoperekera katundu, zomera zambiri ku East China zinkayenda bwino, ndipo mphamvu zotumizira mabizinesi sizinayambitse nyengo yapamwamba ya "Golden Nine", ndipo zosungirako zidakhalabe zapamwamba. Kusintha kwamitengo yamitengo yayikulu ku Shandong sikofunikira. Kufooka kwa msika wapansi panthaka kumakhala kovuta kuwongolera, ndipo kugula kumakhalabe kokhazikika pakungofuna.

3.butyl acetate msika wamakono kusanthula

Domestic butyl acetate idapitilirabe mu Seputembala, ndipo msika udali wofooka. Malinga ndi Business Newswire, kutsika kwa mwezi kwa butyl acetate kunali 2.37%. Kumapeto kwa mwezi, mtengo wapakhomo wa butyl acetate unali 7,200-7,500 yuan/ton.

Kumbali imodzi, mbali yamtengo wapatali idasiyana, ngakhale kuti asidi acetic adabwereranso kumapeto kwa mweziwo, komabe zovuta kuyendetsa kunsi kwa mtsinje wa butyl acetate mumdima, chinthu china chakumtunda n-butanol kugwedezeka pansi, kutsika 2.91% pamwezi. Ponseponse, mbali yotsika mtengo ikadali yolamulidwa ndi mbali yaifupi. Mtengo wanthawi yayitali wa butyl acetate makamaka umachokera ku kukakamizidwa kwa kaphatikizidwe ndi kufunikira: momwe chipangizocho chimayambira, mabizinesi a butyl oyambira amasintha pang'ono, kuchuluka koyambira kwa mbewu zazikulu kusungitsa kumtunda ndi kutsika kwa 40%, koma kukakamizidwa kwazinthu zazikuluzikulu ndizodziwikiratu, chifukwa cha kufunikira kofooka, kugulitsa msika sikwabwino. The terminal amangofuna basi, ndipo msika wonse wamalonda ndi wopepuka.

4.Analysis wa acetic acid industry unyolo

Kuchokera kufananiza tchati cha kukwera ndi kugwa kwa unyolo wa acetic acid, titha kuwona kuti unyolo wamakampaniwo ukuwonetsa chizolowezi chozizira pamwamba ndi kutentha pansi, ndi methanol (19,17%) kumapeto kwa gwero kukwera kwambiri, kuyika kupanikizika kwakukulu pa asidi acetic ndi kunsi kwa mtsinje. Makamaka, kutsika kwa ethyl ester ndi butyl ester akadali omasuka ku msika woipa. Phindu losiyanitsidwa ndi mabizinesi m'mweziwo lidapangitsanso kuti oyambitsa ayambe kukhala otsika, ndikuchotsa koyipa makamaka.

M'kanthawi kochepa, unyolo wa acetic acid udzakhalabe wofooka kumaliza, opanga ma asidi a acetic akhoza kudziunjikira masheya panthawi ya tchuthi, koma kutsika kwa ethyl acetate, butyl acetate ndi PTA kumapitirirabe kudyedwa pa chikondwererochi, ndipo kuwonjezeredwa kwa msika pambuyo pa chikondwererocho kudzabweretsa phindu kwa acetic acid. Komabe, poganizira kusintha pang'ono pakufunika komaliza. Ethyl ester ndi mitengo ya butyl ester ikhoza kukhalabe yofooka.
