1-Butanol ke mofuta oa joala o nang le liathomo tse 'nè tsa carbon tse nang le molek'hule. Foromo ea eona ea molek'hule ke CH3CH2CH2CH2OH e nang le li-isomers tse tharo, e leng iso-butanol, sec-butanol le tert-butanol. Ke mokelikeli o se nang 'mala o nang le monko oa joala.
E na le ntlha e belang ea 117.7 ℃, density (20 ℃) ​​ke 0.8109g/cm3, ntlha ea leqhoa ke-89.0 ℃, flash point ke 36~38 ℃, ntlha ea ho itlhoekisa ke 689F le index ea refractive. ho ba (n20D) 1.3993. Ho 20 ℃, ho qhibiliha ha eona metsing ke 7.7% (ka boima ba 'mele) ha ho qhibiliha ha metsi ho 1-butanol e ne e le 20.1% (ka boima ba 'mele). E kopane le ethanol, ether le mefuta e meng ea lihlapolli tsa tlhaho. E ka sebelisoa e le li-solvents tsa mefuta e fapaneng ea lipente le lisebelisoa tse tala bakeng sa ho hlahisa li-plasticizers, dibutyl phthalate. E ka boela ea sebelisoa bakeng sa ho etsa butyl acrylate, butyl acetate, le ethylene glycol butyl ether hape e sebelisoa e le qotsulo ea li-intermediates tsa organic synthesis le lithethefatsi tsa biochemical hape e ka sebelisoa ha ho etsoa li-surfactants. Mouoane oa eona o ka etsa metsoako e phatlohang ka moea 'me moeli oa ho phatloha e le 3.7% ~ 10.2% (karolo ea molumo).

Kopo:

1. haholo-holo e sebelisoang ha ho etsoa phthalic acid, aliphatic dibasic acid le n-butyl phosphate plasticizers, tse sebelisoang haholo ka mefuta e sa tšoaneng ea polasetiki le lihlahisoa tsa rabara. Hape ke thepa e tala bakeng sa ho etsa butyraldehyde, butyric acid, butylamine le butyl lactate ho organic synthesis. E boetse e sebelisoa e le dehydrating agent, anti-emulsifier le extractant ea oli le grease, lithethefatsi (tse kang lithibela-mafu, lihomone le livithamine) le linoko, le ho eketsa ho roala ha alkyd resin. E boetse e sebelisoa e le solvent bakeng sa lidae tsa manyolo le li-inks tsa khatiso, hape e le sesebelisoa sa dewaxing. E sebelisoa e le solvent ho arola potassium perchlorate le sodium perchlorate, hape e ka arola sodium chloride le lithium chloride. E sebelisetsoa ho hlatsoa sodium zinc uranyl acetate precipitate. E sebelisoa ho etsa qeto ea colorimetric ho fumana asiti ea arsenic ka mokhoa oa molybdate. Boikemisetso ba mafura lebeseng la khomo. E bohareng bakeng sa saponification ea esters. Ho lokisoa ha lintho tse kentsoeng ka parafine bakeng sa microanalysis. E sebelisoa e le solvent bakeng sa mafura, boka, li-resin, shellacs, marenene, joalo-joalo Co-solvent bakeng sa pente ea nitro spray, joalo-joalo.

2. Lintho tse tloaelehileng tsa tlhahlobo ea Chromatographic. E sebelisetsoa ho etsa qeto ea colorimetric ea arsenic acid, solvent bakeng sa karohano ea potasiamo, sodium, lithium le chlorate.
3. Sehlahisoa sa bohlokoa, se sebelisoang ka bongata ha ho etsoa li-resin tsa urea-formaldehyde, li-cellulose resin, li-alkyd resin le lipente, hape e le diluent e tloaelehileng e sa sebetseng ho li-adhesives. Hape ke lisebelisoa tsa bohlokoa tsa lik'hemik'hale tse sebelisoang tlhahisong ea plasticizer dibutyl phthalate, aliphatic dibasic acid ester le phosphate ester. E boetse e sebelisoa e le dehydrating agent, anti-emulsifier le extractant bakeng sa oli, linoko, lithibela-mafu, lihomone, livithamini, joalo-joalo, tlatsetso bakeng sa pente ea alkyd resin, co-solvent bakeng sa pente ea nitro spray, joalo-joalo.
4. Cosmetic solvent. Haholo-holo e sebelisoa e le co-solvent ho polish ea lipekere le litlolo tse ling ho lumellana le solvent e ka sehloohong e kang ethyl acetate, e thusang ho qhaqha 'mala le ho laola ho hloka botsitso le viscosity ea solvent. Chelete ea tlatsetso hangata e ka ba 10%.
5. E ka sebelisoa e le moemeli oa antifoaming bakeng sa ho kopanya enke khatisong ea skrine.
6. E sebelisoa ka thepa e halikiloeng, pudding, candy.
