Isingeniso

I-acetone aldehyde dimethanol, eyaziwa nangokuthi i-acetone methanol. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-acetone aldehyde dimethanol:

 

Ikhwalithi:

I-acetone aldehyde dimethanol iwuketshezi olungenambala ukuya kokuphuzi olunephunga elimnandi. Kuyinhlanganisela yemvelo encibilika emanzini, otshwaleni, nama-ether. I-acetone aldoldehyde methanol ayizinzile, i-hydrolyzed kalula futhi ifakwe i-oxidized, idinga ukugcinwa endaweni ebandayo nemnyama, futhi igcinwe kude nomoya-mpilo, ukushisa kanye nemithombo yokuthungela.

 

Sebenzisa:

I-acetone aldoldehyde dimethanol ivame ukusetshenziswa njengendawo ephakathi kokuhlangana kwe-organic. Ingasetshenziswa ekulungiseni ama-esters, ama-ether, ama-amides, ama-polymers, nezinye izinhlanganisela eziphilayo. I-Pyrudaldehyde methanol iphinde isetshenziswe njenge-solvent, i-ejenti yokumanzisa kanye nesengezo ezimbonini zokumboza nezepulasitiki.

 

Indlela:

Kunezindlela eziningana zokwenza i-acetone aldehyde dimethanol. Indlela evamile itholakala ngokusabela kwe-condensation ye-methanol nge-acetone. Ekulungiseleleni, i-methanol ne-acetone ixutshwe ngesilinganiso esithile se-molar futhi isabela phambi kwe-catalyst ye-acidic, ngokuvamile edinga ukushisa ingxube yokusabela. Ngemuva kokuthi ukusabela sekuqediwe, i-acetone aldoldehyde dimethanol ehlanzekile itholakala ngokugcotshwa, i-crystallization noma ezinye izindlela zokuhlukanisa.

 

Ulwazi Lokuphepha:

I-acetone aldoldemic methanol iyinhlanganisela ecasulayo futhi kufanele igwenywe ngokuthintana ngqo nesikhumba, amehlo, nolwelwesi lwamafinyila. Ukungena komoya okuhle kufanele kwenziwe ngesikhathi sokusebenza, futhi amagilavu ​​okuvikela kanye nezibuko kufanele kugqokwe. Lapho uphatha futhi ugcinwa, isitsha kufanele sivalwe kahle kude nokushisa, ukuvutha kanye nama-oxidants. Uma udliwe noma uhogelwe, funa usizo lwezokwelapha ngokushesha.
