CAS: 64-17-5
Ke ʻano kemika: C2H6O
Wai moakaka ʻole kala. He azeotrope ia o ka wai i hoʻoheheʻe ʻia ma 78.01 ° C. He mea lele ia. Hiki ke hui pū ʻia me ka wai, glycerol, trichloromethane, benzene, ether a me nā mea hoʻoheheʻe organik ʻē aʻe. Nā mea hoʻohui lāʻau lapaʻau, nā mea hoʻoheheʻe. He wai i hoʻomaʻemaʻe ʻole ʻia kēia huahana; ʻAla iki aku; Lele, maʻalahi ke puhi, lapalapa polū māmā; E hoʻolapalapa a hiki i ka 78 ° C. Hiki ke hui pū ʻia kēia huahana me ka wai, glycerin, methane a i ʻole ke kō ethyl.

Ua hoʻolālā ʻia a kūkulu ʻia ka nui o nā papahana ethanol wahie kulina ma Kina, a ʻo ko lākou hoʻolaha ʻana ma kahi e pili pono ana i nā mea maka kulina. ʻO ke kahua kūkulu nui o ka ethanol wahie kulina ma Kina aia nō i nā wahi hana kulina nui ma ka Hikina ʻĀkau o Kina a me Anhui, ʻoiai ʻo nā mea maka i koho ʻia no nā papahana i hoʻolālā ʻia a kūkulu ʻia ma nā wahi me ke aniau kiʻekiʻe a me ke aniau haʻahaʻa e like me ke Komohana Hema, Kina Hema, Hikina Hema a me nā ʻāina ʻo ʻAsia Hikina Hema he cassava, kō a me nā mea kanu wela ʻē aʻe. Eia kekahi, hiki ke kūkulu ʻia ka ethanol wahie ma Shaanxi, Hebei a me nā wahi ʻē aʻe me ka hana lanahu kiʻekiʻe, a ʻo kēia mau papahana he lanahu-a-ethanol. Wahi a nā helu helu, e like me 2022, ʻo ka hana ethanol wahie kulina o Kina ma kahi o 2.23 miliona tone, a ʻo ka waiwai o ka hana ma kahi o 25.333 biliona yuan.

Ma ke ʻano o ka ʻenehana hana ʻana, ʻekolu o ka pūʻulu mua o nā ʻoihana ethanol wahie i koho ʻia i hoʻokomo ʻia i loko o ka hana ma Kina e hoʻohana i ke kaʻina hana pulu. Mai ia manawa, ʻo nā ʻoihana i hoʻokomo ʻia i loko o ka hana e pili ana i ke kaʻina hana maloʻo, a hiki i ka ʻewalu, me ka hoʻololi mau ʻana o ke ʻano hana hana hiki ke hana, ua hoʻolaha wikiwiki ʻia ke kaʻina hana pulu. Ma Kina, ua hoʻolaha nui ʻia ka ethanol wahie kulina ma ka ʻākau hikina o Kina (me ka ʻākau hikina o Inner Mongolia), ʻo Anhui Province a me Henan Province, kahi i kiʻekiʻe ai ka hana kulina.

Ma Nowemapa 15, ua paʻa ka ʻōlelo a kekahi mau mea hana ethanol kūloko
Ua pani ʻia ka hale hana ethanol o Jiangsu Dongcheng Biotechnology 150,000 tons/makahiki, he 6800 yuan/ton ke kumukūʻai o waho o ka ʻoihana. Henan Hanyong 300,000 tons/makahiki ka laina hana hale hana ethanol, he 6700 yuan/ton ke kumukūʻai maikaʻi loa, he 7650 yuan/ton ke kumukūʻai anhydrous me ka hale hana ʻauhau. Shandong Chengguang Industry and Trade Co., LTD. Hana maʻamau ka hale hana ethanol 50,000 tons/makahiki, he 06900 yuan/ton ke kumukūʻai o waho o ka ethanol 95%, he 7750 yuan/ton ke kumukūʻai waho anhydrous.
