Cov khoom siv molecular:

Chemical Properties:

n-Butanol yog cov nplaim taws heev, tsis muaj xim thiab muaj cov yam ntxwv muaj zog tsw, boils ntawm 117 ° C thiab melts ntawm -80 ° C. Cov cuab yeej ntawm cawv no pab txhawb kev tsim cov tshuaj uas xav tau los ua kom tag nrho lub cev txias. n-Butanol muaj tshuaj lom ntau dua li ib qho ntawm nws cov khoom sib xws, xws li sec-butanol, tert-butanol lossis isobutanol.

Daim ntawv thov:

1-Butanol yog qhov tseem ceeb tshaj plaws hauv kev lag luam thiab feem ntau tau kawm. 1-Butanol yog cov kua tsis muaj xim nrog lub zog, muaj ntxhiab tsw ntxhiab tsw. Nws yog siv nyob rau hauv tshuaj derivatives thiab ua ib tug hnyav rau cov xim, waxes, brakes, thiab ntxuav.
Butanol yog cov khoom noj muaj txiaj ntsig uas tau sau tseg hauv "cov qauv kev noj qab haus huv ntxiv" ntawm Tuam Tshoj. Nws yog tsuas yog siv rau kev npaj zaub mov flavors ntawm bananas, butter, cheese thiab whiskey. Rau cov khoom qab zib, tus nqi siv yuav tsum yog 34mg / kg; rau cov zaub mov ci, nws yuav tsum yog 32mg / kg; rau cov dej qab zib, nws yuav tsum yog 12mg / kg; rau cov dej txias, nws yuav tsum yog 7.0mg / kg; rau qab zib, nws yuav tsum yog 4.0mg / kg; rau cawv, nws yuav tsum yog 1.0mg / kg.
Nws yog tsuas yog siv rau kev tsim cov n-butyl plasticizers ntawm phthalic acid, aliphatic dicarboxylic acid thiab phosphoric acid uas tau siv dav rau ntau yam khoom yas thiab roj hmab. Nws kuj tseem tuaj yeem siv los ua cov khoom siv raw ntawm kev tsim cov butyraldehyde, butyric acid, butyl-amine thiab butyl lactate hauv thaj tsam ntawm cov organic synthesis. Nws kuj tseem siv tau los ua tus neeg sawv cev ntawm cov roj, tshuaj (xws li tshuaj tua kab mob, tshuaj hormones thiab vitamins) thiab cov txuj lom nrog rau cov xim alkyd additives. Nws tuaj yeem siv los ua cov kuab tshuaj ntawm cov organic dyes thiab luam ntawv number case thiab de-waxing tus neeg sawv cev.
