I Dekemaba, ua alakaʻi ʻia ka mākeke butyl acetate e ke kumukūʻai. ʻOkoʻa ke kumu kūʻai o ka butyl acetate ma Jiangsu a me Shandong, a ua emi nui ke kumukūʻai ma waena o nā mea ʻelua. Ma ka lā 2 o Dekemaba, he 100 yuan/ton wale nō ke kumu kūʻai ma waena o lāua. I ka wā pōkole, ma lalo o ke alakaʻi ʻana o nā kumu kumu a me nā kumu ʻē aʻe, ua manaʻo ʻia e hoʻi ka ʻokoʻa kumukūʻai ma waena o nā mea ʻelua i kahi pae kūpono.

ʻOiai ʻo ia kekahi o nā wahi hana nui o ka butyl acetate ma Kina, he ākea ākea ʻo Shandong. Ma waho aʻe o ka hoʻohana ponoʻī kūloko, 30% - 40% o ka hopena e kahe pū ana i Jiangsu. ʻO ka ʻokoʻa kumu kūʻai ma waena o Jiangsu a me Shandong i 2022 e mālama mau i kahi ākea arbitrage o 200-300 yuan / ton.

Mai ʻOkakopa, ʻaʻole i ʻoi aku ka nui o ka waiwai o ka butyl acetate ma Shandong a me Jiangsu ma mua o 400 yuan / ton, kahi haʻahaʻa o Shandong. I Kekemapa, ua emi iho ka waiwai o ka butyl acetate, e like me 220 yuan/ton ma Jiangsu a me 150 yuan/ton ma Shandong.

ʻO ka ʻokoʻa o ka loaʻa kālā ma muli o ka ʻokoʻa o ke kumukūʻai o ka n-butanol i ke kumu kūʻai o nā wahi ʻelua. ʻO ka hanaʻana o hoʻokahi tona o ka butyl acetate e pono ai i ka 0.52 tons o ka acetic acid a me ka 0.64 tons o ka n-butanol, aʻo ke kumu kūʻai o ka n-butanol heʻoi aku ka kiʻekiʻe ma mua o ka acetic acid, no laila he nui ka nui o ka n-butanol i ka uku hana. o ka butyl acetate.

E like me ka butyl acetate, ua paʻa ke kumukūʻai o ka n-butanol ma waena o Jiangsu a me Shandong no ka manawa lōʻihi. I nā makahiki i hala iho nei, ma muli o ka loli ʻana o kekahi mau mea kanu n-butanol ma Shandong Province a me nā kumu ʻē aʻe, ke hoʻomau nei ka haʻahaʻa o nā mea kanu ma kēia wahi a he kiʻekiʻe ke kumukūʻai, kahi e loaʻa ai ka waiwai o ka butyl acetate ma Shandong Province. haʻahaʻa maʻamau, a ʻo ka makemake o nā mea hana nui e hoʻomau i ka loaʻa kālā a me ka hoʻouna ʻana he haʻahaʻa a he kiʻekiʻe ke kumukūʻai.

Ma muli o ka ʻokoʻa o ka loaʻa kālā, ʻokoʻa hoʻi ka huahana o Shandong a me Jiangsu. I Nowemapa, ʻo ka huina o ka butyl acetate he 53300 tons, kahi hoʻonui o 8.6% mahina ma ka mahina a me 16.1% makahiki ma ka makahiki.

Ma Kina ʻĀkau, ua hoʻemi nui ʻia ka huahana ma muli o ke kaohi ʻana o ke kumukūʻai. ʻO ka huina o kēlā me kēia mahina ma kahi o 8500 tons, i lalo o 34% mahina ma ka mahina,

ʻO ka huahana ma Kina Hikina ma kahi o 27000 tons, ʻoi aku ka 58% mahina ma ka mahina.

Ma muli o ka hakahaka maopopo ma ka ʻaoʻao hoʻolako, ʻaʻole kūlike ka hoihoi o nā hale hana ʻelua no ka hoʻouna ʻana.

I ka wā ma hope, ʻaʻole koʻikoʻi ka hoʻololi holoʻokoʻa o ka n-butanol ma lalo o ke kumu o ka haʻahaʻa haʻahaʻa, hiki ke hoʻomau i ka emi ʻana o ke kumukūʻai o ka acetic acid, hiki ke hoʻonāwaliwali ke kumu kūʻai o ka butyl acetate, a manaʻo ʻia ka hoʻolako ʻana o Shandong. mahuahua. Manaʻo ʻia ʻo Jiangsu e hōʻemi i kāna lako ma muli o ke kiʻekiʻe o ka hana kūkulu ʻana i ka wā mua a me ka ʻai nui i ka wā e hiki mai ana. Ma lalo o ka ʻaoʻao o luna, ua manaʻo ʻia e hoʻi mālie ke kumukūʻai ma waena o nā wahi ʻelua i ka pae maʻamau.
