Intshayelelo

I-acetal diethanol.

 

Iipropati: I-acetal diethanol lulwelo olungenambala ukuya kumthubi olukhanyayo noxinzelelo lomphunga oluphantsi. Iyanyibilika emanzini, kwiialkoholi, nakwizinyibilikisi ze-ether kwaye iyikhompawundi enozinzo oluhle.

 

Ukusetyenziswa: I-acetal diethanol ine-solubility egqwesileyo, iplastiki kunye neempawu zokumanzisa. Ihlala isetyenziswa njenge-solvent, i-agent yokumanzisa kunye ne-lubricant.

 

Indlela yokulungiselela: i-acetal diethanol ilungiswa ngokubanzi nge-epoxy compound cyclization reaction. I-ethylene oxide iphendulwa ngotywala ukuze ifumane i-ethyl alcohol diethyl ether, ethi emva koko yenziwe yi-acid-catalyzed hydrolysis ukuze yenze i-acetal diethanol.

 

Ulwazi lokhuseleko: I-acetal diethanol yi-compound ephantsi-ityhefu, kodwa kusafuneka ukuba ubeke ingqalelo ekusebenziseni okukhuselekileyo. Kuphephe ukudibana nee-oxidants ezinamandla, ii-asidi ezinamandla kunye ne-oxidants ukuthintela ukusabela kweekhemikhali okanye iingozi eziyingozi. Iiglavu ezifanelekileyo zokukhusela, iiglasi kunye neeovaroli kufuneka zinxitywe ngexesha lokusetyenziswa.
