Isakhiwo samangqamuzana omkhiqizo:

Chemical Properties:

I-1-Butanol wuhlobo lotshwala olunama-athomu ekhabhoni amane aqukethwe nge-molecule ngayinye. Ifomula yayo yamangqamuzana ithi CH3CH2CH2CH2OH enama-isomer amathathu, okuyi-iso-butanol, sec-butanol kanye ne-tert-butanol. Iwuketshezi olungenambala olunephunga lotshwala.
Inephuzu elibilayo elingu-117.7 ℃, ukuminyana (20 ℃) ​​kube ngu-0.8109g/cm3, indawo yokuqandisa ingu-89.0 ℃, i-flash point ingu-36~38 ℃, iphoyinti lokuzithungela ingu-689F kanye nenkomba yokugqama. ukuba (n20D) 1.3993. Ku-20 ℃, ukunyibilika kwayo emanzini kungu-7.7% (ngesisindo) kuyilapho ukuncibilika kwamanzi ku-1-butanol kwaba ngu-20.1% (ngesisindo). Ixubene ne-ethanol, i-ether nezinye izinhlobo zezinyibilikisi zemvelo. Ingasetshenziswa njengezincibilikisi zamapende ahlukahlukene kanye nezinto ezingavuthiwe zokukhiqiza ama-plasticizers, i-dibutyl phthalate. Ingase futhi isetshenziselwe ukwakhiwa kwe-butyl acrylate, i-butyl acetate, ne-ethylene glycol butyl ether futhi iphinde isetshenziselwe ukukhishwa kwe-intermediates ye-organic synthesis kanye nezidakamizwa ze-biochemical futhi ingasetshenziswa nasekwakheni ama-surfactants. Isitimu saso singakha izingxube eziqhumayo ngomoya lapho umkhawulo wokuqhuma ube ngu-3.7%~10.2% (ingxenye yevolumu).

Isicelo:

1. esetshenziswa kakhulu ekwenzeni i-phthalic acid, i-aliphatic dibasic acid kanye ne-n-butyl phosphate plasticizers, asetshenziswa kakhulu kumapulasitiki ahlukahlukene kanye nemikhiqizo yenjoloba. Kuphinde kube yimpahla eluhlaza yokwenza i-butyraldehyde, i-butyric acid, i-butylamine ne-butyl lactate ku-organic synthesis. Ibuye isetshenziswe njenge-ejenti eqeda amanzi emzimbeni, i-anti-emulsifier kanye ne-extractant yamafutha namafutha, izidakamizwa (ezifana nama-antibiotics, amahomoni namavithamini) nezinongo, kanye nesengezo se-alkyd resin coating. Ibuye isetshenziswe njenge-solvent yamadayi we-organic kanye noyinki wokuphrinta, futhi njenge-ejenti yokukhipha inwayi. Isetshenziswa njenge-solvent ukuhlukanisa i-potassium perchlorate ne-sodium perchlorate, futhi ingahlukanisa i-sodium chloride ne-lithium chloride. Isetshenziselwa ukugeza i-sodium zinc uranyl acetate precipitate. Isetshenziswa ekunqumeni kombala ukuze kunqunywe i-arsenic acid ngendlela ye-molybdate. Ukunqunywa kwamafutha obisi lwenkomo. Okumaphakathi kwe-saponification yama-esters. Ukulungiswa kwezinto ezifakwe upharafini ze-microanalysis. Isetshenziswa njenge-solvent yamafutha, ama-wax, ama-resin, ama-shellac, izinsini, njll. I-Co-solvent yopende we-nitro spray, njll.

2. Izinto ezijwayelekile zokuhlaziywa kweChromatographic. Isetshenziselwa ukuzimisela kwe-colorimetric ye-arsenic acid, i-solvent yokuhlukanisa i-potassium, i-sodium, i-lithium ne-chlorate.
3. I-solvent ebalulekile, esetshenziswa ngobuningi ekukhiqizeni ama-urea-formaldehyde resins, ama-cellulose resins, ama-alkyd resins namapende, futhi njenge-diluent evamile engasebenzi kuma-adhesives. Iphinde ibe yikhemikhali ebalulekile esetshenziswa ekukhiqizeni i-plasticizer dibutyl phthalate, i-aliphatic dibasic acid ester kanye ne-phosphate ester. Ibuye isetshenziswe njenge-ejenti eqeda amanzi emzimbeni, i-anti-emulsifier kanye ne-extractant yamafutha, izinongo, ama-antibiotics, amahomoni, amavithamini, njll., okungeziwe ngopende we-alkyd resin, i-co-solvent yopende we-nitro spray, njll.
4. I-solvent yezimonyo. Isetshenziswa kakhulu njenge-co-solvent ku-nail polish nezinye izimonyo ukuze ihambisane ne-solvent eyinhloko njenge-ethyl acetate, esiza ukuncibilikisa umbala futhi ilawule ukuguquguquka kanye ne-viscosity ye-solvent. Inani elingeziwe ngokuvamile liba ngu-10%.
5. Ingasetshenziswa njenge-ejenti ye-antifoaming yokuhlanganisa uyinki ekuphrinteni kwesikrini.
6. Isetshenziswa ezimpahleni ezibhakwayo, uphudingi, uswidi.
