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

Intshayelelo

I-Octalal diacetal. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-octanal diethylacetal:

Umgangatho:

I-Octanal diacetal lulwelo olungenambala noluphawu lwevumba le aldehydes. Ingulwelo olunamafutha angaguqukiyo kunye nobuninzi be-0.93 g / cm3 kwiqondo lokushisa. Iyanyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol kunye ne-ethers.

Sebenzisa:

I-Octanal diacetal ineendlela ezahlukeneyo zokusetyenziswa kwishishini lemichiza. I-Octanal diacetal nayo ingasetyenziswa njengesithako kwizibulali zinambuzane kunye nezitshabalalisi.

Indlela:

Ukulungiswa kwe-diacetal ye-octanal kunokufumaneka ngokusabela kwe-n-hexanal kunye ne-ethanol. Ngokuqhelekileyo, i-n-hexanal kunye ne-ethanol ixutywe kumlinganiselo othile we-molar, ilandelwa yimpendulo kwiqondo lokushisa elifanelekileyo kunye noxinzelelo, kwaye ekugqibeleni i-diacetal ecocekileyo ye-octanal ihlukaniswe yi-distillation.

Ulwazi loKhuseleko: I-Octanal diacetal yikhemikhali ecasulayo enokubangela ukucaphuka kunye nokuvuvukala ngokudibana nolusu kunye namehlo, kwaye kufuneka kuthathelwe ingqalelo ukuphepha ukudibanisa ngokuthe ngqo. Izixhobo ezifanelekileyo zokukhusela ezinjengeeglavu, iiglasi kunye nempahla yokukhusela kufuneka zinxitywe xa usebenza. Xa ugcina kwaye uhambisa, ukudibana nee-oxidants kunye ne-acids ezomeleleyo kufuneka kugwenywe ukukhusela ukuphendula okuyingozi. Xa ingasetyenziswa, kufuneka itywinwe ngokufanelekileyo kwaye igcinwe ukuphepha ukudibanisa nemithombo yomlilo. Kwimeko yokungenwa okanye ukuphefumla ngempazamo, funa unyango ngokukhawuleza.
