CAS 71-36-3

Sifooyinka jirka iyo kiimikada

n-Butanol, oo sidoo kale loo yaqaan 1-butanol ama butanol, waa nooc ka mid ah khamriga. Molekul kasta wuxuu leeyahay afar atamka kaarboon, qaacidada molekulkiisuna waa CH3CH2CH2CH2OH. Waxaa jira saddex isomers, kuwaas oo kala ah isobutanol, sec-butanol iyo tert-butanol. Waa dareere aan midab lahayn oo leh ur khamri heerkulka qolka. Barta karkaraya waa 117.7°C, cufnaanta (20°C) waa 0.8109g/cm3, barta barafowga waa -89.0°C, barta iftiimaysa waa 36~38°C, barta is-shiditaankana waa 689F. Tusmada Refractive Book (n20D) waa 1.3993. Milmideeda biyaha 20°C waa 7.7% (miisaan), milmideeda n-butanolna waa 20.1% (miisaan). Waxaa lagu milan karaa ethanol, ether iyo dareere kale oo badan oo dabiici ah. Uumigeedu wuxuu sameeyaa isku-darka qarxa oo leh hawo, xadka qaraxiisuna waa 3.7% ~ 10.2% (jajab mugga). Butanol waa walaxda ceeriin ah ee lagu soo saaro dibutyl phthalate oo ah plasticizer, waxaana sidoo kale loo isticmaalaa in lagu sameeyo dareereyaal loogu talagalay butyl acrylate, butyl acetate, iyo ethylene glycol butyl ether.

Isticmaalka

N-Butanol waxaa inta badan loo isticmaalaa in lagu sameeyo phthalic acid, dibutyl phthalate, aliphatic dibasic acid iyo n-butyl ester plasticizers oo ka samaysan fosforic acid, kuwaas oo si weyn loogu isticmaalo balaastikada kala duwan iyo alaabada caagga ah. Sidoo kale waa walaxda ceeriin ee lagu sameeyo butyraldehyde, butyric acid, butyl acetate, butylamine Chemicalbook iyo butyl lactate marka la samaynayo isku-darka dabiiciga ah. Sidoo kale waa soo-saare loogu talagalay soo saarista resin melamine, acrylic acid, saliidaha, daawooyinka (sida antibiyootikada, hoormoonada iyo fiitamiinnada) iyo xawaashka, iyo wax lagu daro dahaarka resin alkyd. Waxa kale oo loo isticmaali karaa sidii dareere loogu talagalay midabaynta dabiiciga ah iyo khadadka daabacaadda, wakiil dewaxing, iwm.
