Iipropati zeMichiza:

I-1-Butanol luhlobo lotywala oluneeathom ezine zekhabhoni eziqulethwe kwi-molecule nganye.Ifomula yayo yemolekyuli yi-CH3CH2CH2CH2OH ene-isomers ezintathu, ezizezi, iso-butanol, sec-butanol kunye ne-tert-butanol.Lulwelo olungenambala nevumba lotywala.
Inendawo yokubila eyi-117.7 ℃, ingxinano (20 ℃) ​​yi-0.8109g/cm3, indawo yokukhenkceka ibe ngu-89.0 ℃, i-flash point ibe yi-36~38 ℃, indawo yokuzitshisa ibe ngu-689F kunye nesalathiso se-refractive. ukuba (n20D) 1.3993.Kwi-20 ℃, ukunyibilika kwayo emanzini yi-7.7% (ngobunzima) ngelixa ukunyibilika kwamanzi kwi-1-butanol kwakuyi-20.1% (ngobunzima).Iyaxubana ne-ethanol, i-ether kunye nezinye iintlobo zezinyibilikisi eziphilayo.Ingasetyenziselwa njengezinto ezinyibilikayo zemibala eyahlukeneyo yepeyinti kunye nezinto eziluhlaza zokuvelisa i-plasticizers, i-dibutyl phthalate.Isenokusetyenziswa ukwenza i-butyl acrylate, i-butyl acetate, kunye ne-ethylene glycol butyl ether kwaye isetyenziswe njengesicatshulwa se-intermediates ye-organic synthesis kunye namachiza e-biochemical kwaye ingasetyenziswa ekwenzeni izinto ezixutywayo.Umphunga wayo unokwenza imixube eqhumayo kunye nomoya kwaye umda wokudubula ube yi-3.7% ~ 10.2% (iqhezu lomthamo).

Isicelo:

1. isetyenziswa kakhulu ekwenzeni i-phthalic acid, i-aliphatic dibasic acid kunye ne-n-butyl phosphate plasticizers, ezisetyenziswa ngokubanzi kwiindidi zeplastiki kunye neemveliso zerabha.Ikwayimathiriyeli ekrwada yokwenza ibutyraldehyde, butyric acid, butylamine kunye nebutyl lactate kwi-organic synthesis.Ikwasetyenziswa njenge-agent ephelisa amanzi emzimbeni, i-anti-emulsifier kunye ne-extractant yeoli kunye negrisi, iziyobisi (ezifana ne-antibiotics, iihomoni kunye neevithamini) kunye neziqholo, kunye ne-additive of alkyd resin coating.Ikwasetyenziselwa ukunyibilikisa idayi eziphilayo kunye nee-inki zokuprinta, kwaye njenge-agent ekhupha.Isetyenziswe njenge-solvent ukwahlula i-potassium perchlorate kunye ne-sodium perchlorate, nayo inokwahlula i-sodium chloride kunye ne-lithium chloride.Isetyenziselwa ukuhlamba i-sodium zinc uranyl acetate precipitate.Isetyenziselwa ukuzimisela kwe-colorimetric ukumisela i-arsenic acid ngendlela ye-molybdate.Ukuzimisela kwamafutha kubisi lwenkomo.Okuphakathi kwi-saponification ye-esters.Ukulungiswa kwezinto ezifakwe kwiparafini kwi-microanalysis.Isetyenziswe njenge-solvent yamafutha, i-wax, i-resins, i-shellac, iintsini, njl njl. I-Co-solvent ye-nitro spray paint, njl.

2. Uhlalutyo lweChromatographic izinto ezisemgangathweni.Isetyenziselwa ukuzimisela kwe-colorimetric ye-arsenic acid, i-solvent yokwahlula i-potassium, i-sodium, i-lithium kunye ne-chlorate.
3. I-solvent ebalulekileyo, esetyenziswe ngobuninzi obukhulu ekuveliseni i-urea-formaldehyde resins, i-cellulose resins, i-alkyd resins kunye nepeyinti, kwaye kwakhona njenge-diluent engasebenziyo eqhelekileyo kwi-adhesives.Ikwayinto ebalulekileyo yeekhemikhali ezisetyenziselwa ukuveliswa kwe-plasticizer dibutyl phthalate, i-aliphatic dibasic acid ester kunye ne-phosphate ester.Ikwasetyenziswa njenge-ejenti yokuchitha amanzi, i-anti-emulsifier kunye ne-extractant ye-oyile, iziqholo, i-antibiotics, iihomoni, iivithamini, njl.
4. I-solvent yokuthambisa.Isetyenziswa kakhulu njenge-co-solvent kwi-nail polish kunye nezinye izimonyo ukuze zihambelane ne-solvent ephambili efana ne-ethyl acetate, enceda ukunyibilikisa umbala kunye nokulawula ukuguquguquka kunye ne-viscosity ye-solvent.Isixa esongeziweyo siqhelekile malunga ne-10%.
5. Ingasetyenziswa njenge-agent ye-antifoaming yokudibanisa i-inki ekushicileleni isikrini.
6. Isetyenziswe kwizinto ezibhakiweyo, i-pudding, i-candy.
