I-Octanal diethyl acetal(CAS#54889-48-4)

Isingeniso

I-Octalal diacetal. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-octanal diethylacetal:

Ikhwalithi:

I-Octanal diacetal iwuketshezi olungenambala olunephunga elimnandi lama-aldehydes. Iwuketshezi olunamafutha angaguquguquki olunobuningi obungu-0.93 g/cm3 ekamelweni lokushisa. Incibilika kuzincibilikisi zemvelo njenge-ethanol nama-ether.

Sebenzisa:

I-Octanal diacetal inezinhlobonhlobo zezicelo embonini yamakhemikhali. I-Octanal diacetal ingasetshenziswa futhi njengesithako kwizibulala-zinambuzane nezibulala-zinambuzane.

Indlela:

Ukulungiswa kwe-octanal diacetal kungatholakala ngokusabela kwe-n-hexanal ne-ethanol. Ngokuvamile, i-n-hexanal ne-ethanol ixutshwe ngesilinganiso esithile se-molar, ilandelwa ukusabela ekushiseni okufanelekile nokucindezela, futhi ekugcineni i-diacetal ye-octanal ehlanzekile ihlukaniswa yi-distillation.

Ulwazi Lokuphepha: I-Octanal diacetal ikhemikhali ecasulayo engase ibangele ukucasuka nokuvuvukala lapho kuthinta isikhumba namehlo, futhi ukunakekelwa kufanele kuthathwe ukuze kugwenywe ukuthintana okuqondile. Izimpahla zokuzivikela ezifanele njengamagilavu, izibuko, nezingubo zokuzivikela kufanele zigqokwe lapho kusebenza. Lapho ugcina futhi uthutha, ukuthintana nama-oxidants nama-asidi aqinile kufanele kugwenywe ukuvimbela ukusabela okuyingozi. Uma ingasetshenziswa, kufanele ivalwe kahle futhi igcinwe ukuze kugwenywe ukuthintana nemithombo yomlilo. Esimeni sokungena ngephutha noma ukuhogela, funa usizo lwezokwelapha ngokushesha.
