1-Butanol

I-CAS 71-36-3

Iimpawu zomzimba nezekhemikhali

I-n-Butanol, ekwaziwa ngokuba yi-1-butanol okanye i-butanol, luhlobo lotywala. Imolekyuli nganye inee-athomu ezine zekhabhoni kwaye ifomula yayo yemolekyuli yi-CH3CH2CH2CH2OH. Kukho ii-isomers ezintathu, ezizezi: i-isobutanol, i-sec-butanol kunye ne-tert-butanol. Lulwelo olungenambala olunevumba lewayini kubushushu begumbi. Iqondo layo lokubila yi-117.7°C, uxinano (20°C) yi-0.8109g/cm3, iqondo lokuqandisa yi--89.0°C, iqondo lokukhanya yi-36~38°C, kwaye iqondo lokuzitshisa yi-689F. I-Refractive index Chemicalbook (n20D) yi-1.3993. Ukunyibilika kwayo emanzini kwi-20°C yi-7.7% (ubunzima), kwaye ukunyibilika kwayo kwi-n-butanol yi-20.1% (ubunzima). Ixutywa ne-ethanol, i-ether kunye nezinye izinyibilikisi ezininzi ze-organic. Umphunga wayo wenza umxube oqhumayo nomoya, kwaye umda wayo wokuqhuma yi-3.7% ~ 10.2% (inxalenye yomthamo). I-Butanol yinto esetyenziswayo ukuvelisa i-plasticizer dibutyl phthalate, kwaye ikwasetyenziselwa ukwenza izinyibilikisi ze-butyl acrylate, i-butyl acetate, kunye ne-ethylene glycol butyl ether.

Ukusetyenziswa

I-N-Butanol isetyenziswa kakhulu ekwenzeni i-phthalic acid, i-dibutyl phthalate, i-aliphatic dibasic acid kunye ne-n-butyl ester plasticizers ze-phosphoric acid, ezisetyenziswa kakhulu kwiiplastiki ezahlukeneyo kunye neemveliso zerabha. Ikwayimveliso eluhlaza yokwenza i-butyraldehyde, i-butyric acid, i-butyl acetate, i-butylamine Chemicalbook kunye ne-butyl lactate kwi-organic synthesis. Ikwayi-extractant yokuvelisa i-melamine resin, i-acrylic acid, iioyile, amayeza (afana nee-antibiotics, ii-hormones kunye neevithamini) kunye neziqholo, kunye ne-additive kwi-alkyd resin coatings. Ingasetyenziswa njenge-solvent ye-organic dyes kunye ne-printing inks, i-dewaxing agent, njl.njl.
