Ethanol
CAS: 64-17-5 Nr
Cov tshuaj formula: C2H6O
Colorless pob tshab kua. Nws yog azeotrope ntawm dej distilled ntawm 78.01 ° C. Nws yog volatile. Nws tuaj yeem ua rau miscible nrog dej, glycerol, trichloromethane, benzene, ether thiab lwm yam organic solvents. Pharmaceutical excipients, kuab tshuaj. Cov khoom no yog cov kua tsis muaj xim tsis meej; me ntsis tsw ntxiv; Volatile, yooj yim rau hlawv, hlawv lub teeb xiav nplaim; Boil rau txog 78 ° C. Cov khoom no tuaj yeem ua rau miscible nrog dej, glycerin, methane lossis ethyl qab zib.

Ntau cov pob kws roj ethanol tej yaam num yog npaj thiab tsim nyob rau hauv Tuam Tshoj, thiab lawv spatial faib yog obviously muaj feem xyuam rau pob kws raw cov ntaub ntawv. Qhov chaw tsim kho tseem ceeb ntawm pob kws roj ethanol hauv Suav teb tseem yog nyob rau hauv cov pob kws tseem ceeb hauv cheeb tsam Northeast Tuam Tshoj thiab Anhui, thaum cov khoom siv raw xaiv rau cov haujlwm tau npaj thiab tsim hauv thaj chaw uas muaj qhov kub thiab txias xws li Southwest, South China, Cov teb chaws sab hnub tuaj thiab sab hnub tuaj Asia feem ntau yog qos yaj ywm, qab zib thiab lwm cov qoob loo kub. Tsis tas li ntawd, roj ethanol tuaj yeem tsim tau hauv Shaanxi, Hebei thiab lwm thaj chaw uas muaj cov thee ntau lawm, thiab cov haujlwm no feem ntau yog cov thee-rau-ethanol. Raws li kev txheeb cais, txij li xyoo 2022, Tuam Tshoj cov pob kws roj ethanol ntau lawm yog kwv yees li 2.23 lab tons, thiab cov nqi tso tawm yog kwv yees li 25.333 billion yuan.

Nyob rau hauv cov nqe lus ntawm ntau lawm technology, peb ntawm thawj batch ntawm xaiv roj ethanol tuam txhab uas muag muab tso rau hauv ntau lawm nyob rau hauv Tuam Tshoj siv cov txheej txheem ntub dej. Txij thaum ntawd los, cov tuam txhab muab tso rau hauv kev tsim khoom feem ntau yog raws li cov txheej txheem qhuav qhuav, txog li yim, nrog rau kev hloov pauv tsis tu ncua ntawm cov txheej txheem tsim muaj peev xwm, cov txheej txheem ntub dej tau nce nrawm dua. Hauv Suav teb, pob kws roj ethanol feem ntau yog faib rau sab qaum teb sab hnub tuaj ntawm Tuam Tshoj (xws li sab qaum teb sab hnub tuaj ntawm Inner Mongolia), Anhui Xeev thiab Henan Province, qhov twg cov pob kws ntau lawm.

Thaum Lub Kaum Ib Hlis 15, cov lus hais ntawm qee cov tuam txhab ethanol hauv tsev tau ruaj khov
Jiangsu Dongcheng Biotechnology 150,000 tons / xyoo cassava qib ethanol cog kaw, qib kev lag luam sab nraud 6800 yuan / ton. Henan Hanyong 300,000 tons / xyoo ethanol cog ntau lawm kab, zoo heev tus nqi ntawm 6700 yuan / ton, anhydrous nqi ntawm 7650 yuan / tuj nrog rau lub Hoobkas se. Shandong Chengguang Kev Lag Luam thiab Kev Lag Luam Co., Ltd. 50,000 tons / xyoo ethanol cog ib txwm ua haujlwm, 95% ethanol sab nraud hais 06900 yuan / ton, anhydrous sab nraud siv 7750 yuan / ton.
