Dab tsi yog kev siv ethanol?

[Siv 1]
Ethanol yog siv los ua cov khoom siv tshuaj lom neeg yooj yim, thiab tseem siv los ua cov kuab tshuaj organic, ua cawv cawv, thiab kev lag luam zaub mov.
[Siv 2]
Ethanol feem ntau yog siv los ua cov tshuaj analytical reagent thiab tseem siv hauv kev lag luam tshuaj.
[Siv 3]
Ethanol yog siv rau hauv kev lag luam cawv, organic synthesis, tshuaj tua kab mob, thiab ua kuab tshuaj. Calibration instruments thiab pab kiag li lawm; txoj kev ntsuam xyuas; cov qauv ua haujlwm; quality assurance/zoo tswj.
[Siv 4]
Ethanol yog ib qho tseem ceeb ntawm cov ntaub ntawv raw cov ntaub ntawv, dav siv hauv cov organic synthesis, tshuaj, tshuaj tua kab thiab lwm yam lag luam, thiab kuj yog ib qho tseem ceeb organic hnyav.
[Siv 5]
Ethanol yog dav siv nyob rau hauv cov organic synthesis industries xws li yas, hluavtaws fibers, thiab hluavtaws roj hmab.
[Siv 6]
Ethanol yog siv los ua tus kheej lub lauj kaub kub roj, sab nraum zoov tourism roj, thiab lwm yam.
[Siv 7]
Ethanol extraction hnyav; xim cab kuj; tsw kuab tshuaj; tsw enhancer; khaws cia. GB 2760-96 teev tias nws yog kev pab ua zaub mov.
[Siv 8]
Ethanol yog ib qho tseem ceeb ntawm cov kuab tshuaj organic, dav siv hauv tshuaj, txheej, tshuaj ntxuav tes, tshuaj pleev ib ce, roj thiab rog, thiab lwm yam, suav txog li 50% ntawm tag nrho cov ethanol noj. Ethanol yog ib qho tseem ceeb ntawm cov khoom siv raw, siv los ua acetaldehyde, ethylenediene, ethylamine, ethyl acetate, acetic acid, ethyl chloride, thiab lwm yam, thiab muab tau los ntawm ntau cov tshuaj intermediates, dyes, coatings, fragrances, hluavtaws roj hmab, tshuaj detergents, tshuaj tua kab. thiab lwm yam khoom. Muaj ntau tshaj 300 yam khoom, tab sis kev siv ethanol ua ib qho nruab nrab ntawm cov khoom siv tshuaj yog maj mam poob. Ntau yam khoom xws li acetaldehyde, acetic acid, thiab ethyl ethanol tsis siv ethanol ua raw khoom tab sis siv lwm cov ntaub ntawv raw. 75% ethanol aqueous tov muaj zog bactericidal muaj peev xwm thiab yog ib tug nquag siv tshuaj tua kab mob. Tshwj xeeb refined ethanol kuj siv tau los ua dej haus. Zoo ib yam li methanol, ethanol tuaj yeem siv los ua lub zog. Qee lub tebchaws tau pib siv ethanol ib leeg ua roj tsheb lossis sib tov nrog roj av (ntau tshaj 10%) kom txuag tau roj av.
[Siv 9]
Ethanol tuaj yeem siv los ua cov kuab tshuaj, organic synthesis, crystallization ntawm ntau lub tebchaw, tshuaj ntxuav tes, tus neeg sawv cev extraction.
