1-Butanol

I-CAS 71-36-3

Izakhiwo zomzimba nezamakhemikhali

I-n-Butanol, eyaziwa nangokuthi i-1-butanol noma i-butanol, uhlobo lotshwala. I-molecule ngayinye inama-athomu amane e-carbon futhi ifomula yayo yama-molecule yi-CH3CH2CH2CH2OH. Kunezinhlobo ezintathu zama-isomer, okuyi-isobutanol, i-sec-butanol kanye ne-tert-butanol. Iwuketshezi olungenambala olunephunga lewayini ekushiseni kwegumbi. Iphuzu layo lokubila lingu-117.7°C, ubuningi (20°C) bungu-0.8109g/cm3, iphuzu lokuqandisa lingu-89.0°C, iphuzu lokushaza lingu-36~38°C, kanti iphuzu lokuzisha lingu-689F. I-Refractive index Chemicalbook (n20D) ingu-1.3993. Ukuncibilika kwayo emanzini ku-20°C kungu-7.7% (isisindo), kanti ukuncibilika kwayo ku-n-butanol kungu-20.1% (isisindo). Ixutshwa ne-ethanol, i-ether nezinye izinto eziningi eziphilayo. Umhwamuko wayo wakha ingxube eqhumayo nomoya, futhi umkhawulo wayo wokuqhuma ungu-3.7% ~ 10.2% (ingxenye yevolumu). I-Butanol iyinto eluhlaza yokukhiqiza i-plasticizer dibutyl phthalate, futhi isetshenziselwa ukwenza izinyibilikisi ze-butyl acrylate, i-butyl acetate, kanye ne-ethylene glycol butyl ether.

Ukusetshenziswa

I-N-Butanol isetshenziswa kakhulu ekwenzeni i-phthalic acid, i-dibutyl phthalate, i-aliphatic dibasic acid kanye ne-n-butyl ester plasticizers ye-phosphoric acid, esetshenziswa kabanzi kumapulasitiki ahlukahlukene kanye nemikhiqizo yerabha. Futhi iyinto eluhlaza yokwenza i-butyraldehyde, i-butyric acid, i-butyl acetate, i-butylamine Chemicalbook kanye ne-butyl lactate ekuhlanganisweni kwezinto eziphilayo. Futhi iyi-extractant yokukhiqiza i-melamine resin, i-acrylic acid, amafutha, izidakamizwa (ezifana nama-antibiotic, ama-hormone namavithamini) kanye nezinongo, kanye nesithasiselo se-alkyd resin coatings. Ingasetshenziswa futhi njengesithasiselo samadayi e-organic kanye nama-printing inks, i-dewaxing agent, njll.
