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 zokunyibilikisa ezahlukeneyo zepeyinti kunye nezinto ezikrwada 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 ezixutywe kunye ne-surfactants. Umphunga wayo unokwenza imixube eqhumayo kunye nomoya kwaye umda wokudubula ube yi-3.7% ~ 10.2% (iqhezu lomthamo).

Isicelo:

1. ikakhulu esetyenziswa 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-shellacs, i-gums, 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-mali esongeziweyo siqhelekile malunga ne-10%.
5. Ingasetyenziswa njenge-agent ye-antifoaming yokudibanisa i-inki ekushicileleni isikrini.
6. Isetyenziswe kwizinto ezibhakiweyo, i-pudding, i-candy.
