Izakhiwo Zomzimba Nezamakhemikhali Uketshezi oluguquguqukayo olungenambala. Iphoyinti elibilayo lika-103.2 deg C, 21 deg C (2.93kPa), ukuminyana okuhlobene kuka-0.8314(20.4 deg C), inkomba yokuphinda iphindeke ye-1.3834. Ixubene ne-ethanol ne-ether. Incibilika emanzini, i-acetic acid, i-heptane, i-butanol ne-ethyl acetate. Isitoreji sesikhathi eside kulula ukusihlanganisa. Izinzile ku-alkaline.
Sebenzisa Isetshenziswa njengesengezo esibalulekile sotshwala, singasetshenziswa njenge-solvent, kodwa futhi nasekuhlanganiseni udayi, amapulasitiki, izinongo, njll.

Isingeniso

I-acetal diethanol.

 

Izakhiwo: I-acetal diethanol iwuketshezi olungenambala ukuya kokuphuzi olukhanyayo nokucindezela komhwamuko ophansi. Iyancibilika emanzini, otshwaleni, nasezincibilikisini ze-ether futhi iyinhlanganisela enozinzo oluhle.

 

Ukusetshenziswa: I-acetal diethanol ine-solubility enhle kakhulu, ipulasitiki kanye nezakhiwo zokumanzisa. Ivame ukusetshenziswa njenge-solvent, i-ejenti yokumanzisa kanye ne-lubricant.

 

Indlela yokulungiselela: i-acetal diethanol ngokuvamile ilungiswa nge-epoxy compound cyclization reaction. I-Ethylene oxide iphendulwa ngotshwala ukuze kutholwe i-ethyl alcohol diethyl ether, esuke isungulwe i-acid-catalyzed hydrolysis ukuze yakhe i-acetal diethanol.

 

Ulwazi lokuphepha: I-acetal diethanol iyinhlanganisela enobuthi obuphansi, kodwa kusadingeka ukuthi unake ukusetshenziswa okuphephile. Gwema ukuthintana nama-oxidants aqinile, ama-asidi aqinile nama-oxidants ukuvimbela ukusabela kwamakhemikhali noma izingozi eziyingozi. Amagilavu ​​okuvikela afanelekile, izibuko, namaovaroli kufanele kugqokwe ngesikhathi sokusetshenziswa.
