Guryaha Kiimikada:

1-Butanol waa nooc ka mid ah khamriga oo ay ku jiraan afar atamka kaarboon halkii molecule. Qaabka molecular-keeda waa CH3CH2CH2CH2OH oo leh saddex isomers, kuwaas oo kala ah iso-butanol, sec-butanol iyo tert-butanol. Waa dareere aan midab lahayn oo leh ur aalkolo.
Waxay leedahay barta karkarinta ee ahaanshaha 117.7 ℃, cufnaanta (20 ℃) ​​oo ah 0.8109g/cm3, barta qaboojintu waa -89.0 ℃, barta toosan oo ah 36 ~ 38 ℃, barta is-shidida oo ah 689F iyo tusaha refractive ahaanshaha (n20D) 1.3993. Marka la joogo 20 ℃, milmaheeda biyaha waa 7.7% (miisaan ahaan) halka milanka biyaha ee 1-butanol uu ahaa 20.1% (miisaan ahaan). Waxay la mid tahay ethanol, ether iyo noocyada kale ee dareerayaasha organic. Waxaa loo isticmaali karaa sida dareerayaasha rinjiyada kala duwan iyo alaabta ceeriin ee soo saarista balaastikada, dibutyl phthalate. Waxa kale oo loo isticmaali karaa soo saarista butyl acrylate, butyl acetate, iyo ethylene glycol butyl ether sidoo kale waxa loo isticmaali karaa in laga soo saaro dhex dhexaadinta isku dhafka dabiiciga ah iyo dawooyinka kimikalka waxaana sidoo kale loo isticmaali karaa soo saarida surfactants. Uumigeedu wuxuu samayn karaa isku dhafka qarxa oo hawo leh iyadoo xadka qaraxa uu yahay 3.7% ~ 10.2% (mugga jajab).

Codsiga:

1. inta badan waxaa loo isticmaalaa soo saarista phthalic acid, aliphatic dibasic acid iyo balaastikada n-butyl phosphate, kuwaas oo si weyn loogu isticmaalo baco iyo alaabooyin kala duwan. Sidoo kale waa alaabta ceeriin ee samaynta butyraldehyde, butyric acid, butylamine iyo butyl lactate ee isku-dhafka dabiiciga ah. Waxa kale oo loo isticmaalaa sida wakiilka fuuq-baxa, anti-emulsifier iyo soo saarista saliidda iyo dufanka, daawooyinka (sida antibiyootiga, hormoonnada iyo fiitamiinnada) iyo uunsiga, iyo wax lagu daro daaha alkyd resin. Waxa kale oo loo isticmaalaa sida dareere loogu talagalay midabaynta organic iyo daabacaadda daabacaadda, iyo wakiilka dewaxing. Loo isticmaalo sida dareere si loo kala saaro potassium perchlorate iyo sodium perchlorate, sidoo kale waxay kala saari kartaa chloride sodium iyo lithium chloride. Waxaa loo isticmaalaa in lagu dhaqo sodium zinc uranyl acetate precipitate. Waxaa loo adeegsaday go'aaminta colorimetric si loo go'aamiyo arsenic acid habka molybdate. Go'aaminta dufanka caanaha lo'da. Dhexdhexaad u ah saponification of esters. Diyaarinta walxaha paraffin-ku-xidhan ee falanqaynta microanalysis. Waxaa loo isticmaalaa sida dareere loogu talagalay dufanka, dhuka, xabagta, shellacs, ciridka, iwm

2. Falanqaynta Chromatographic walxaha caadiga ah. Loo isticmaalo go'aaminta colorimetric ee arsenic acid, dareeraha kala soocida potassium, sodium, lithium iyo chlorate.
3. Walxaha muhiimka ah, oo loo isticmaalo tiro badan oo soo saarista xabagta urea-formaldehyde, resins cellulose, alkyd resins iyo rinji, iyo sidoo kale sida dareeraha aan firfircoonayn ee caadiga ah ee xabagta. Sidoo kale waa walxo kiimiko ah oo ceeriin ah oo muhiim ah oo loo isticmaalo soo saarista balaastikada dibutyl phthalate, aliphatic dibasic acid ester iyo phosphate ester. Waxa kale oo loo isticmaalaa sida wakiilka fuuq-baxa, anti-emulsifier iyo soosaaraha saliidaha, xawaashka, antibiyootiga, hormoonnada, fiitamiinnada, iwm., lagu daro rinjiga alkyd resin, co-solvent for nitro spray rinjiga, iwm.
4. dareeraha qurxinta. Waxaa inta badan loo isticmaalaa sida isku-darka ah ee ciddiyaha iyo waxyaabaha kale ee la isku qurxiyo si ay ula mid noqoto dareeraha ugu muhiimsan sida ethyl acetate, taas oo ka caawisa in ay milaan midabka iyo nidaaminta isbeddelka iyo viscosity ee dareeraha. Qadarka dheeriga ah guud ahaan waa ilaa 10%.
5. Waxa loo isticmaali karaa sidii wakiilka foaming-ka ee khad isku darka daabacaadda shaashadda.
6. Loo isticmaalo alaabta la dubay, pudding, nacnaca.
