1. Ka nānā 'ana i ke au o ka mākeke acetic acid
I ka malama o Feberuari, ua hoike mai ka acetic acid i ke ano fluctuating, me ka pii mua ana o ke kumukuai a haule iho.I ka hoʻomaka ʻana o ka mahina, ʻo ke kumu kūʻai o ka acetic acid he 3245 yuan/ton, a i ka hopena o ka mahina, he 3183 yuan/ton ke kumu kūʻai, me ka emi ʻana o 1.90% i loko o ka mahina.
I ka hoʻomaka ʻana o ka mahina, ua kū ka mākeke acetic acid me nā kumukūʻai kiʻekiʻe a hoʻomaikaʻi i ka noi.Eia kekahi, ma muli o ka nānā ʻana i kekahi mau mea hana, ua emi ka lako, a ua piʻi nui ke kumukūʻai ma ke kūkulu ʻākau;Mai ka waena o ka mahina a hiki i ka hopena o ka mahina, ua nele ka mākeke i nā pono hou aʻe, ua paʻakikī ke kumukūʻai kiʻekiʻe e mālama, a ua huli ka mākeke i ka emi ʻana.Hoʻomaka hou ka mea kanu i ka hana, ua lawa ka lako holoʻokoʻa, a ʻo ke kūʻē ʻana ma waena o ka lako a me ke koi i alakaʻi ʻia i ka nalowale o ka pono kumu kūʻai.Ma ka hopena o ka mahina, ʻo ke kumukūʻai kūʻai nui o ka acetic acid i ka laulā o 3100-3200 yuan / ton.
2. Ka nānā 'ana i ke au o ka mākeke o ka ethyl acetate
I kēia mahina, ua haʻalulu nāwaliwali ka ethyl acetate, a ua hoʻomaka nā hale hana nui ma Shandong e hana, a ua hoʻonui ʻia ka lako i hoʻohālikelike ʻia me kēlā.Ua kāohi ʻia ka ethyl acetate e ka hāʻawi ʻana a me ke koi ʻana, ʻoi aku hoʻi i nā lā he ʻumi mua, ʻaʻole i ʻike i nā pono o ke kumu kūʻai o ka acetic acid.Wahi a ka ʻikepili o Business News Agency, ʻo ka emi ʻana o kēia mahina he 0.24%.Ma kahi kokoke i ka hopena o ka mahina, ʻo ke kumukūʻai mākeke o ka ethyl acetate ʻo 6750-6900 yuan / ton.
ʻO ke kikoʻī, ʻike ʻia ke anuanu o ke kālepa o ka mākeke ethyl acetate i kēia mahina, a ʻoi aku ka liʻiliʻi o ke kūʻai ʻana i lalo, a ʻo ke ʻano kālepa o ka ethyl acetate aia i loko o ka 50 yuan.I ka waena o ka mahina, ʻoiai ua hoʻoponopono ʻia nā hale hana nui, ua kaupalena ʻia ka laulā o ka fluctuation, a ʻo ka hapa nui o lākou e hoʻomalu ʻia i loko o 100 yuan.Ua hoʻopaʻa ʻia nā ʻōlelo a ka hapa nui o nā mea hana nui, a ua hoʻemi iki ʻia nā kumukūʻai o kekahi mau mea hana ma Jiangsu i ka waena o ka mahina ma muli o ka hopena o ke kaomi waiwai.Ke noi nei nā mea hana nui o Shandong no ka hoʻouna ʻana.Ke hōʻike mau nei ke kumukūʻai i ka hilinaʻi ʻole.ʻOiai aia kahi kuʻikahi premium, ʻaʻole i ʻoi aku ke kumukūʻai ma mua o ke kiʻekiʻe o ka mahina i hala.Ua hāʻule ke kumukūʻai o nā mea maka a me ka acetic acid i ka waena a me ka hopena o ka mākeke, a ke kū nei ka mākeke i kahi kumukūʻai maikaʻi ʻole.
3. Ka nānā 'ana o ke au makeke o ka butyl acetate
I kēia mahina, ua hoʻi hou ka butyl acetate ma muli o ka paʻa o ka lako.Wahi a ka nānā ʻana o Business News Agency, ua piʻi ka butyl acetate i ka 1.36% i kēlā me kēia mahina.I ka hopena o ka mahina, ʻo 7400-7600 yuan/ton ke kumukūʻai butyl ester kūloko.
ʻO ka mea kikoʻī, ua nāwaliwali ka hana o ka wai acetic maka, a ua hāʻule nui ka n-butanol, me ka emi ʻana o 12% i Pepeluali, ʻaʻole ia no ka mākeke butyl ester.ʻO ke kumu nui o ke kumu kūʻai o ka butyl ester ʻaʻole i hahai i ka emi ʻana ma ka ʻaoʻao hoʻolako, ua haʻahaʻa ka helu hana o nā ʻoihana, mai 40% i Ianuali a 35%.Ua paa ka lako.He koʻikoʻi ka manaʻo e kali a ʻike i lalo, ʻaʻohe hana o ka mākeke, a he kakaikahi ke kālepa o nā kauoha nui, a ʻo ke ʻano o nā lā he ʻumi i hala.Ua koi ʻia kekahi mau ʻoihana e hoʻoponopono ma lalo o ke kūlana o ke kumu kūʻai kiʻekiʻe, a ʻaʻole ulu nui ka mākeke a me ka noi.
4. Nā manaʻo e hiki mai ana o ke kaulahao ʻoihana acetic acid

I ka wā pōkole, ua hui pū ʻia ka mākeke me ka lōʻihi a me ka pōkole, ʻoiai ke kumukūʻai maikaʻi ʻole, hiki ke hoʻomaikaʻi ka noi.Ma ka ʻaoʻao hoʻokahi, aia nō ka hoʻohaʻahaʻa i lalo i nā kumukūʻai o luna, e lawe mai i nā lono maikaʻi ʻole i ke kaulahao ʻoihana acetic acid.Eia nō naʻe, ʻoi aku ka haʻahaʻa o ka hana o ka ʻakika acetic upstream a me ka downstream ethyl a me butyl ester.He haʻahaʻa nō hoʻi ka waihona waiwai.Me ka hoʻomau mau ʻana o ka noi terminal i ka pae hope, e piʻi mālie ke kumukūʻai o ka ethyl ester, butyl ester a me nā huahana ʻē aʻe.
