I-Diisopropyl ether

Iimpawu zekhemikhali:

Ulwelo olungenambala, olumanzi nolunokutsha olunokuguquguquka okuphakathi, olunevumba elikhethekileyo le-ether. Lungenza i-azeotrope enamanzi, i-isopropyl alcohol, i-acetone, i-acetonitrile kunye ne-ethanol.

Injongo:

I-Diisopropyl ether sisinyibilikisi esilungileyo seeoyile zezilwanyana, zemifuno nezeminerali kunye namafutha. Ingasetyenziselwa ukutsala i-nicotine kwicuba. Ikwasisinyibilikisi esilungileyo se-paraffin wax kunye ne-resin. Kwishishini, i-diisopropyl ether idla ngokuxutywa nezinye izinyibilikisi ukuze isetyenziswe kwiimveliso ezisekwe kwiparaffin. Inkqubo yokunyibilikisa ioyile. Njengesinyibilikisi, ikwasetyenziswa kumayeza, kwiikhemikhali ezingenamsi, kwiingubo kunye nokucoca ipeyinti. I-Diisopropyl ether inenani eliphezulu le-octane kunye neempawu zokulwa nokuqandisa kwaye ingasetyenziswa njengearhente yokuxuba ipetroli. Le mveliso yenza lula i-peroxide kwaye iqhume xa ishukunyiswa. I-Para-benzylaminophenol idla ngokufakwa njengesiqinisi. Isiphumo se-anesthetic se-diisopropyl ether silula kunese-diethyl ether, kodwa ixesha le-anesthesia lide.

Indlela yokuvelisa Kwishishini, ingafunyanwa kwimveliso ye-isopropyl alcohol eveliswa ngokufuthwa kwe-propylene sulfuric acid. I-Propylene isabela ne-sulfuric acid ukwenza i-isopropyl hydrosulfate, eya kuthi emva koko i-hydrolyzed ibe yi-isopropyl alcohol. Ngexesha lokusabela, i-isopropyl hydrogen sulfate kunye ne-propylene ziyaqhubeka nokusabela ekwenzeni i-diisopropyl sulfate, esabela ne-isopropyl alcohol ukwenza i-isopropyl hydrogen sulfate kunye ne-diisopropyl ether. Emva kokusabela kwe-sulfuric acid hydration, izinto zeChemicalbook zisuswa ngomphunga kwi-desorption tower ukuze kukhutshwe i-isopropyl alcohol kunye ne-diisopropyl ether kwisisombululo se-asidi. Emva koko, nge-distillation, i-diisopropyl ether ifunyanwa kuqala phezulu kwi-tower. Kwilabhoratri, i-isopropyl ether ingafunyanwa ngokufuthwa kwe-isopropyl alcohol nge-sulfuric acid, okanye ngokufuthwa kwe-isopropyl alcohol kunye ne-acetone. Ingakhiwa nangokufuthwa kwe-catalytic ye-isopropyl alcohol kunye ne-propylene. I-Diisopropyl ether inokwenziwa ngendlela ye-ion exchange resin.
