Abubuwan Sinadarai:

1-Butanol wani nau'in barasa ne mai dauke da sinadarin carbon atom guda hudu a cikin kowace kwayar halitta. Tsarin kwayoyin halittarsa ​​shine CH3CH2CH2CH2OH tare da isomers guda uku, wato iso-butanol, sec-butanol da tert-butanol. Ruwa ne mara launi tare da warin barasa.
Yana yana da tafasar batu na kasancewa 117.7 ℃, da yawa (20 ℃) ​​kasancewa 0.8109g / cm3, daskarewa batu kasancewa-89.0 ℃, flash batu zama 36 ~ 38 ℃, kai- ƙonewa batu zama 689F da refractive index. kasancewa (n20D) 1.3993. A 20 ℃, da solubility a cikin ruwa ne 7.7% (ta nauyi) yayin da ruwa solubility a 1-butanol ya 20.1% (ta nauyi). Yana da haɗari tare da ethanol, ether da sauran nau'ikan kaushi na kwayoyin halitta. Ana iya amfani dashi azaman kaushi na fenti iri-iri da albarkatun ƙasa don samar da filastik, dibutyl phthalate. Hakanan za'a iya amfani dashi don kera butyl acrylate, butyl acetate, da ethylene glycol butyl ether kuma ana iya amfani dashi azaman tsantsa tsaka-tsakin ƙwayoyin ƙwayoyin cuta da magungunan ƙwayoyin cuta kuma ana iya amfani da su wajen kera na'urorin surfactants. Tururinsa na iya haifar da abubuwan fashewa tare da iska tare da iyakar fashewar kasancewa 3.7% ~ 10.2% (ƙarashin juzu'i).

Aikace-aikace:

1. galibi ana amfani da su wajen kera phthalic acid, aliphatic dibasic acid da n-butyl phosphate plasticizers, wadanda ake amfani da su sosai a cikin nau’ikan robobi da kayayyakin roba. Har ila yau, shi ne danyen kayan da ake yin butyraldehyde, butyric acid, butylamine da butyl lactate a cikin hadadden kwayoyin halitta. Ana kuma amfani da shi azaman wakili na dehydrating, anti-emulsifier da cirewar mai da maiko, magunguna (kamar maganin rigakafi, hormones da bitamin) da kayan yaji, da ƙari na murfin resin alkyd. Hakanan ana amfani dashi azaman sauran ƙarfi don rini na halitta da tawada na bugu, kuma azaman wakili na dewaxing. An yi amfani da shi azaman kaushi don raba potassium perchlorate da sodium perchlorate, kuma yana iya raba sodium chloride da lithium chloride. Ana amfani dashi don wanke sodium zinc uranyl acetate precipitate. Ana amfani da ƙayyadaddun ƙayyadaddun launi don ƙayyade arsenic acid ta hanyar molybdate. Ƙaddamar da mai a cikin madarar saniya. Matsakaici don saponification na esters. Shirye-shiryen abubuwan da ke cikin paraffin don microanalysis. Ana amfani da shi azaman sauran ƙarfi don mai, waxes, resins, shellacs, gumis, da sauransu. Co-solvent don feshin nitro, da sauransu.

2. Chromatographic bincike daidaitattun abubuwa. Ana amfani dashi don ƙaddarar launi na arsenic acid, mai ƙarfi don rabuwa da potassium, sodium, lithium da chlorate.
3. Mahimmin ƙarfi mai mahimmanci, wanda aka yi amfani dashi da yawa a cikin samar da resin urea-formaldehyde, resin cellulose, alkyd resins da fenti, da kuma a matsayin mai narkewa marar aiki na yau da kullum a cikin adhesives. Har ila yau, wani muhimmin sinadari mai mahimmanci da aka yi amfani da shi wajen samar da plasticizer dibutyl phthalate, aliphatic dibasic acid ester da phosphate ester. Hakanan ana amfani dashi azaman wakili na dehydrating, anti-emulsifier da cirewa don mai, kayan yaji, maganin rigakafi, hormones, bitamin, da sauransu, ƙari don fentin resin alkyd, mai ƙarfi don feshin nitro, da sauransu.
4. Maganin shafawa. Ana amfani da shi ne a matsayin co-solvent a cikin ƙusa goge da sauran kayan shafawa don dacewa da babban kaushi kamar ethyl acetate, wanda ke taimakawa wajen narkar da launi da daidaita rashin daidaituwa da danko na sauran ƙarfi. Adadin ƙarin shine gabaɗaya kusan 10%.
5. Ana iya amfani dashi azaman wakili na antifoaming don haɗuwa da tawada a cikin bugu na allo.
6. Ana amfani dashi a cikin kayan da aka gasa, pudding, alewa.
