N-Butyl Alcohol (CAS 71-36-3) yog dab tsi?
N-Butyl cawv (CAS 71-36-3)yog cov xim tsis muaj xim, pob tshab kua organic nrog cov mis molecular C₄H₁₀O, cais raws li cawv. Nws muaj cov ntxhiab tsw ntxhiab tsw ntxhiab, nthuav tawm qhov kub siab kub, thiab yog ib feem miscible nrog dej, txawm hais tias nws yooj yim dua soluble hauv cov kuab tshuaj organic xws li ethanol thiab diethyl ether. n-Butanol nthuav tawm cov khoom siv tshuaj lom neeg, koom nrog ntau yam tshuaj tiv thaiv nrog rau esterification, oxidation, thiab hloov pauv. Industrially, nws feem ntau yog tsim los ntawm propylene carbonylation los yog ua los ntawm cov txheej txheem fermentation.
1-Butanol (CAS 71-36-3)
1-Butanol (n-Butanol) yog ib qho tseem ceeb organic compound nrog cov tshuaj formula C₄H₁₀O, cais raws li saturated monohydric cawv. n-Butanol muaj cov yam ntxwv hauv qab no:
Lub cev muaj zog:n-Butanol yog cov kua tsis muaj xim, pob tshab uas muaj ntxhiab tsw zoo ib yam li cawv. Nws qhov ceev yog 0.81 g / cm³, kub taw tes yog 117.7 degree, thiab melting point yog -89.5 degree. n-Butanol pom zoo volatility thiab dej solubility. Nws cov qauv molecular muaj ib pab pawg hydroxyl (-OH), imparting polarity uas tso cai rau miscibility nrog ntau yam polar thiab nonpolar solvents.
Chemical Properties:n-Butanol qhia cov khoom siv tshuaj lom neeg nrog rau lwm yam cawv, suav nrog:
- Oxidation Reactions: Nyob rau hauv catalyst lossis siab - qhov kub thiab txias, n-butanol tuaj yeem oxidized rau n-butyraldehyde lossis butyric acid.
- Esterification Reaction : Reacts nrog acids los tsim cov ester tebchaw, xws li butyl acetate thaum reacting nrog acetic acid, uas yog ib qho hnyav hnyav.
- Lub cev qhuav dej: Raws li cov kua qaub catalysis, n-butanol raug lub cev qhuav dej los tsim cov butene.
- Kev hloov pauv: Cov pab pawg hydroxyl tuaj yeem hloov tau los ntawm halogens lossis lwm pab pawg ua haujlwm.
Kev siv 1-Butanol (CAS 71-36-3) yog dab tsi?
- Cov kuab tshuaj: N-Butyl cawv (CAS 71-36-3) yog ib qho hnyav heev rau ntau txheej txheej, inks, thiab resins, ua kom pom kev ua tau zoo tshwj xeeb hauv nitrocellulose lacquers thiab acrylic resins. Nws qhov nruab nrab evaporation tus nqi txhim kho txheej txheej thiab ziab kom qhuav.
- Tshuaj Raw Khoom: Raws li cov tshuaj tseem ceeb nruab nrab, n-butanol yog siv los ua ke esters xws li butyl acetate thiab dibutyl phthalate. Cov khoom no tau siv ntxiv hauv kev tsim cov yas yas, tshuaj tsw qab, thiab cov nplaum.
- Fuel Additive: N-Butyl Cawv yog ib qho khoom siv roj ntsha biofuel sib xyaw nrog cov roj av txhawm rau txhim kho kev sib xyaw ua ke thiab txo cov pa tawm. Nws muaj zog ceev thiab zoo heev compatibility nrog roj av.
- Lwm Daim Ntawv Thov: Hauv cov tshuaj thiab tshuaj tua kab, N-Butyl Cawv ua haujlwm ua tus neeg sawv cev rho tawm lossis cov tshuaj tiv thaiv nruab nrab. Hauv cov tshuaj hauv tsev, nws yog siv los ua cov tshuaj tsw qab thiab cov tshuaj ntxuav tes.
