Intshayelelo
I-acetone aldehyde dimethanol, ekwabizwa ngokuba yi-acetone methanol. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-acetone aldehyde dimethanol:
Umgangatho:
Iacetone aldehyde dimethanol lulwelo olungenambala ukuya kumthubi nevumba elibi. Yikhompawundi ephilayo enyibilikayo emanzini, kwiialkoholi, nakwiethers. I-acetone aldoldehyde methanol ayizinzile, i-hydrolyzed ngokulula kwaye i-oxidized, idinga ukugcinwa kwindawo ebandayo kunye nendawo emnyama, kwaye igcinwe kude ne-oksijini, ubushushu kunye nemithombo yokutshisa.
Sebenzisa:
I-acetone aldoldehyde dimethanol isoloko isetyenziswa njengendawo ephakathi kwi-organic synthesis. Ingasetyenziselwa ukulungiswa kwee-esters, i-ethers, i-amides, ii-polymers, kunye nezinto ezithile eziphilayo. I-Pyrudaldehyde methanol iphinda isetyenziswe njenge-solvent, i-agent yokumanzisa kunye ne-additive kumashishini eengubo kunye neeplastiki.
Indlela:
Kukho iindlela ezininzi zokulungiselela i-acetone aldehyde dimethanol. Indlela eqhelekileyo ifunyenwe yi-condensation reaction ye-methanol nge-acetone. Ukulungiselela, i-methanol kunye ne-acetone zixutywe kwinqanaba elithile le-molar kwaye ziphendule phambi kwe-catalyst acidic, edla ngokufuna ukufudumeza umxube wokuphendula. Emva kokuba impendulo igqityiwe, i-acetone aldoldehyde dimethanol ecocekileyo ifunyenwe nge-distillation, i-crystallization okanye ezinye iindlela zokwahlula.
Ulwazi ngoKhuseleko:
I-acetone aldoldemic methanol yikhompawundi ecaphukisayo kwaye kufuneka igwenywe ngokudibana ngokuthe ngqo nolusu, amehlo kunye nenwebu. Ukungena komoya okulungileyo kufuneka kuqhutywe ngexesha lokusebenza, kwaye iiglavu zokukhusela kunye nezibuko kufuneka zigqitywe. Xa uphathwa kunye nokugcinwa, isikhongozelo kufuneka sivalwe kakuhle kude nobushushu, ukutshisa kunye ne-oxidants. Ukuba utyiwe okanye urholile, funa unyango ngokukhawuleza.
