I kēia makahiki, ua lohi ka mākeke acetone home, ka mālama holoʻokoʻa o ke ʻano oscillation haʻahaʻa, no kēia mākeke ʻehaʻeha, he poʻo nui nō hoʻi nā mea kālepa, akā ke emi mālie nei ka mākeke oscillation, ke ʻano ʻenehana o ka triangle convergence.

Mai kēia makahiki, ʻoiai ua mālama ka mākeke i kahi haʻahaʻa haʻahaʻa, ua hōʻike ʻia ke ʻano holoʻokoʻa i kahi oscillation ikaika, ʻoi aku ka ikaika o ke kākoʻo ma hope o kēlā me kēia luʻu, a ua piʻi ka haʻahaʻa o ka mākeke i ka hoʻohālikelike ʻia me nā haʻahaʻa mua, e lawe ana i ka mākeke East China ma ke ʻano he laʻana, ʻo ka helu haʻahaʻa loa i Iune i ka makahiki i hala he 4875 yuan/ton, ʻo ka haʻahaʻa haʻahaʻa i Dekemaba o ka makahiki i hala he 5100 yuan/ton, a ʻo ka haʻahaʻa haʻahaʻa ma Dekemaba o ka makahiki i hala he 5100 yuan/ton. yuan/ton hou, 'o ia hoʻi Ma hope o ka hāʻule ʻana o ka mākeke i 5000 yuan / ton kokoke i kahi kākoʻo kūʻai ikaika, a ke hoʻi hou nei ka mākeke.

I kēia mau lā, ua loaʻa hou ka mākeke i luna, e kokoke ana e wāwahi i ka pae puʻe triangle convergence, ʻo Jin Lianchuang ka mea i ʻoi aku ka nui o ka acetone upward breakthrough, ʻoi aku ka lōʻihi o ka hoʻohui ʻana o ka mākeke i nā ʻaoʻao lōʻihi a pōkole, e kali ana i ka nūhou hou e hoʻoulu.

ʻO ke kumu o ka Acetone, ke ʻano maikaʻi.

ʻO ka mea mua, ʻo Yangzhou Shanyou 320,000 tons / makahiki phenol ketone mea kanu mālama, nā ʻoihana i ka waihona waiwai, manaʻo ʻia e hoʻomaka hou i ka hoʻomaka o Iune. ʻO ka lua, ua hōʻemi ʻia ka maʻi maʻi ma Shanghai, hoʻomaka hou nā moku haole, e hoʻonui ʻia ka noi o lalo.

ʻO ke kolu, ʻo ke kumu waiwai maʻemaʻe benzene ikaika, kākoʻo kumu kūʻai maikaʻi, benzene maʻemaʻe a me ka ʻokoʻa kumu kūʻai acetone, indirectly ʻoluʻolu acetone, a me nā ʻoihana phenol ketone i hāʻule i loko o nā poho, inā hoʻomau nā poho ma lalo o ka hale hana e lawe i kahi hōʻemi liʻiliʻi i nā ana maikaʻi ʻole.

ʻO ka hā, ua emi iki ka waihona o ke awa, i loko o ʻApelila ka waihona waiwai awa ma Jiangyin ma ke kiʻekiʻe o 50,000 tons, ʻo ka waihona acetone o kēia manawa o 37,000 tons level, ua hoʻemi ʻia mai ka waihona kiʻekiʻe i kahi pae kūpono.

ʻO ka ʻelima, ʻo ke kumukūʻai kiʻekiʻe o nā waiwai i lawe ʻia mai, ʻoi aku ka kiʻekiʻe o ka lawe ʻana iā ia iho ma mua o nā kumukūʻai makeke kūloko, hui pū ʻia me ka piʻi wikiwiki ʻana o ke kumukūʻai kālā, e hoʻonui hou ana i ke kumukūʻai o nā waiwai i lawe ʻia mai.

I ka hōʻuluʻulu ʻana, ʻoi aku ka ikaika o ka acetone i ka wā e hiki mai ana, koi, ʻoiai ʻoi aku ka nāwaliwali, akā ʻo ka hoʻomaikaʻi ʻana o ka maʻi maʻi, aia nō kahi wahi no ka hoʻomaikaʻi ʻana, acetone i ke kumu kūʻai haʻahaʻa, palena ʻia ka manaʻo ʻae ʻoihana, ua manaʻo ʻia ka mākeke acetone inā piʻi ka wikiwiki, e hoʻoulu i ka nalu o ka loaʻa kālā, hiki ke ʻike hou ʻia e hōʻoia, inā e hoʻomau ka mākeke a hoʻomau i ka ikaika.
