1-Butanol

CAS 71-36-3

Kapangidwe ka thupi ndi mankhwala

n-Butanol, yomwe imadziwikanso kuti 1-butanol kapena butanol, ndi mtundu wa mowa. Molekyu iliyonse ili ndi ma atomu anayi a kaboni ndipo mawonekedwe ake a molekyulu ndi CH3CH2CH2CH2OH. Pali ma isomer atatu, omwe ndi isobutanol, sec-butanol ndi tert-butanol. Ndi madzi opanda mtundu omwe ali ndi fungo la vinyo kutentha kwa chipinda. Malo ake otentha ndi 117.7°C, kuchuluka kwa (20°C) ndi 0.8109g/cm3, malo ozizira ndi -89.0°C, malo owunikira ndi 36~38°C, ndipo malo ozimitsira okha ndi 689F. Refractive index Chemicalbook (n20D) ndi 1.3993. Kusungunuka kwake m'madzi pa 20°C ndi 7.7% (kulemera), ndipo kusungunuka kwake mu n-butanol ndi 20.1% (kulemera). Amasakanikirana ndi ethanol, ether ndi zinthu zina zambiri zachilengedwe. Nthunzi yake imapanga chisakanizo chophulika ndi mpweya, ndipo malire ake ophulika ndi 3.7% ~ 10.2% (gawo la voliyumu). Butanol ndi chinthu chopangira pulasitiki dibutyl phthalate, ndipo imagwiritsidwanso ntchito popanga zosungunulira za butyl acrylate, butyl acetate, ndi ethylene glycol butyl ether.

Ntchito

N-Butanol imagwiritsidwa ntchito kwambiri popanga phthalic acid, dibutyl phthalate, aliphatic dibasic acid ndi n-butyl ester plasticizers za phosphoric acid, zomwe zimagwiritsidwa ntchito kwambiri mu mapulasitiki osiyanasiyana ndi zinthu za rabara. Ndi chinthu chopangira butyraldehyde, butyric acid, butyl acetate, butylamine Chemicalbook ndi butyl lactate mu organic synthesis. Ndi chinthu chochotsera mankhwala opangira melamine resin, acrylic acid, mafuta, mankhwala (monga maantibayotiki, mahomoni ndi mavitamini) ndi zonunkhira, komanso chowonjezera cha alkyd resin coatings. Ingagwiritsidwenso ntchito ngati solvent ya utoto wa organic ndi inki zosindikizira, dewaxing agent, ndi zina zotero.
