I ka pule i hala aku nei, ua piʻi a piʻi ke kumukūʻai o isopropanol. ʻO ke kumukūʻai maʻamau o isopropanol ma Kina he 6870 yuan / ton i ka pule i hala, a me 7170 yuan / ton i ka Pōʻalima i hala. Ua hoʻonui ke kumukūʻai e 4.37% i ka pule.

Kiʻi: Hoʻohālikelike o nā kumukūʻai o 4-6 Acetone a me Isopropanol
ʻO ke kumukūʻai o ka isopropanol ke loli a piʻi. I kēia manawa, maikaʻi ke kūlana hoʻokuʻu aku o nā kauoha isopropanol. Maikaʻi ke kūlana kālepa kūloko. ʻO ka mākeke isopropanol kūloko ke ʻano ikaika, me ka piʻi ʻana o nā kumukūʻai o ka mākeke acetone upstream, a me ke kākoʻo kumu kūʻai e alakaʻi i ka piʻi ʻana o nā kumukūʻai mākeke isopropanol. ʻOi aku ka ikaika o nā nīnau i lalo, a ke koi ʻia ke kūʻai. ʻO ka ʻōlelo no Shandong isopropanol ka hapa nui ma kahi o 6750-7000 yuan / ton; ʻO ka ʻōlelo no Jiangsu isopropanol ma kahi o 7300-7500 yuan / ton.

I ka ʻōlelo o ka acetone maka, ua piʻi wikiwiki ka mākeke acetone home mai Iulai. Ma Iulai 1st, ʻo ke kumukūʻai i kūkākūkā ʻia ma ka mākeke acetone East China he 5200-5250 yuan / ton. Ma Iulai 20th, ua piʻi ke kumukūʻai o ka mākeke i 5850 yuan/ton, he piʻi kumulative o 13.51%. I ke alo o ka lako o ka mākeke paʻa a me nā pilikia i ka hoʻomaikaʻi ʻana i ka wā pōkole, ua piʻi ka hoihoi o nā mea kālepa waena e komo i ka mākeke, ua hoʻonui ʻia ka makemake o ka waihona, a ua hoʻomaikaʻi maikaʻi ʻia ka lewa nīnau no nā ʻoihana nui lalo e komo i ka mākeke, me piʻi mau ka manaʻo makeke.

Ma ke ʻano o ka propylene maka, i kēia pule ua kāohi mua ʻia ka mākeke propylene (Shandong) a laila ala aʻe, me ka emi iki ʻana. ʻO ke kumu kūʻai maʻamau o ka mākeke Shandong i ka hoʻomaka ʻana o ka pule he 6608 yuan/ton, ʻoiai ke kumu kūʻai maʻamau i ka hopena pule he 6550 yuan/ton, me ka emi ʻana o kēlā me kēia pule he 0.87% a me ka emi ʻana o ka makahiki he 11.65%. . Manaʻo ka poʻe loiloi propylene ma ka Commercial Chemical Branch i ka holoʻokoʻa, ʻaʻole maopopo nā kumukūʻai aila honua, akā ʻike ʻia ke kākoʻo koi i lalo. Manaʻo ʻia e holo ikaika ka mākeke propylene i ka wā pōkole.
I kēia manawa, maikaʻi nā kauoha hoʻokuʻu aku a ke hana nei nā hana kūloko. Ua hoʻonui ʻia ke kumukūʻai o ka acetone, a ua ikaika ke kākoʻo o nā mea maka no ka isopropanol. Manaʻo ʻia e hana mau ka isopropanol a hoʻomaikaʻi i ka wā pōkole.
