I-Diisopropyl ether

Izakhiwo zamakhemikhali:

Uketshezi olungenambala, oluwuketshezi noluvuthayo olunokuguquguquka okuphakathi, olunephunga elikhethekile le-ether. Lungakha i-azeotrope enamanzi, i-isopropyl alcohol, i-acetone, i-acetonitrile kanye ne-ethanol.

Inhloso:

I-Diisopropyl ether iyisithako esihle samafutha ezilwane, imifino kanye namaminerali namafutha. Ingasetshenziswa ukukhipha i-nicotine kugwayi. Futhi iyisithako esihle samafutha e-paraffin kanye ne-resin. Embonini, i-diisopropyl ether ivame ukuhlanganiswa nezinye izithako ukuze isetshenziswe emikhiqizweni esekelwe ku-paraffin. Inqubo yokususa i-oyili. Njengesithako, isetshenziswa futhi kwezemithi, amakhemikhali angenantuthu, ukumboza kanye nokuhlanza upende. I-Diisopropyl ether inenombolo ephezulu ye-octane kanye nezakhiwo zokulwa nokubanda futhi ingasetshenziswa njenge-ejenti yokuxuba uphethiloli. Lo mkhiqizo wakha kalula i-peroxide futhi uqhume uma unyakaziswa. I-Para-benzylaminophenol ivame ukungezwa njengesithako. Umphumela wokubulala izinzwa we-diisopropyl ether ulula kunowe-diethyl ether, kodwa isikhathi se-anesthesia side.

Indlela Yokukhiqiza Ezimbonini, ingatholakala kumkhiqizo ongaphansi kwe-isopropyl alcohol okhiqizwa ngokumanzisa i-propylene sulfuric acid. I-Propylene isabela ne-sulfuric acid ukuze yakhe i-isopropyl hydrosulfate, bese i-hydrolyzed ibe yi-isopropyl alcohol. Ngesikhathi sokusabela, i-isopropyl hydrogen sulfate kanye ne-propylene ziyaqhubeka nokusabela ekwakheni i-diisopropyl sulfate, esabela ne-isopropyl alcohol ukuze yakhe i-isopropyl hydrogen sulfate kanye ne-diisopropyl ether. Ngemva kokusabela kwe-sulfuric acid hydration, izinto ze-Chemicalbook zihlutshulwa ngomusi embhoshongweni wokudonswa ukuze kukhishwe i-isopropyl alcohol kanye ne-diisopropyl ether esixazululweni se-acid. Ngemuva kwalokho, nge-distillation, i-diisopropyl ether itholwa kuqala phezulu kombhoshongo. Elabhorethri, i-isopropyl ether ingatholakala ngokumanzisa i-isopropyl alcohol nge-sulfuric acid, noma ngokumanzisa i-isopropyl alcohol kanye ne-acetone. Ingakhiwa futhi ngokujiya kwe-catalytic kwe-isopropyl alcohol kanye ne-propylene. I-Diisopropyl ether ingakhiqizwa futhi ngendlela ye-ion exchange resin.
