N-Butanol, tseem hu ua 1-butanol, yog ib qho organic compound nrog cov tshuaj formula C₄H₁₀O thiab molecular hnyav 74.12 g / mol. Nws yog xim tsis muaj xim, pob tshab kua nrog cov ntxhiab tsw ntxhiab, me ntsis soluble hauv dej tab sis soluble hauv feem ntau cov organic solvents xws li ethanol thiab ether. Plaub carbon atoms nyob rau hauv n-butanol lub molecule yog teem raws li nyob rau hauv ib tug ncaj saw, nrog rau cov hydroxyl pawg (OH) txuas mus rau lub davhlau ya nyob twg carbon atom. Cov qauv no muab lub sijhawm electrostatic dipole rau lub molecule, lub ntsiab lus ib kawg yog tus nqi zoo thaum lwm tus nqa tus nqi tsis zoo.
1-Butanol siv
- Ua ntej, nws yog ib qho tseem ceeb raw khoom rau kev tsim n-butyl esters ntawm phthalic acid, aliphatic dicarboxylic acids, thiab phosphoric acid-plasticizers feem ntau siv nyob rau hauv ntau yam yas thiab roj hmab khoom.
- Tsis tas li ntawd, nws ua hauj lwm ua ib tug precursor rau tsim butyraldehyde, butyric acid, butylamine, thiab butyl lactate nyob rau hauv cov organic synthesis.
- Tsis tas li ntawd,n-butanolua hauj lwm raws li ib tug extractant rau cov rog, tshuaj (xws li tshuaj tua kab mob, tshuaj hormones, thiab vitamins), thiab flavorings, raws li zoo raws li ib tug additive nyob rau hauv alkyd resin coatings.
- Nyob rau hauv kev lag luam tshuaj, nws kuj ua raws li ib tug hnyav rau cov organic dyes thiab luam ntawv inks, thiab raws li ib tug dewaxing neeg sawv cev.
- Hauv kev lag luam khoom noj khoom haus, n-butanol kuj tseem siv los tsim cov khoom qab zib rau txiv tsawb, qab zib, whiskey, thiab cheese.
Muaj peb txoj hauv kev tseem ceeb rau kev tsim N-Butanol:
Fermentation, acetaldehyde synthesis, thiabpropylene carbonylation synthesis. Txawm li cas los xij, nrog kev nce qib ntawm petrochemical thev naus laus zis, txoj kev fermentation tau raug txiav tawm. Cov txheej txheem acetaldehyde synthesis siv acetaldehyde ua cov khoom siv raw, ua n-butanol los ntawm cov tshuaj lom neeg ntau. Txoj kev propylene carbonylation synthesis siv propylene, carbon monoxide, thiab hydrogen ua feedstocks, reacting nyob rau hauv tej catalysts thiab tej yam kev mob rau yield n-butanol.
Thov nco ntsoov tias thaum n-butanol muaj ntau daim ntawv thov thoob plaws ntau lub teb, nws kuj ua rau muaj kev phom sij. Nws yog flammable, muaj teeb meem yog tias nqos, thiab tuaj yeem ua rau ua pa thiab tawv nqaij. Yog li ntawd, kev ua raws li cov cai tswj kev nyab xeeb thiab kev ceev faj yog qhov tseem ceeb thaum nws siv thiab khaws cia.
Nyem qhov no kom tau txais qhov tseeb thoob ntiaj teb1-butanol (CAS71-36-3) kev lag luam tus nqi rau xyoo 2026.
