trans-2-Hexen-1-Al Diethyl Acetal(CAS#54306-00-2) ukwazisa
impahla ebonakalayo
Imbonakalo: Ngokuqhelekileyo kubonakala njengolwelo olungenambala ukuya ekukhanyeni okutyheli olucacileyo, okwenza kube lula ngakumbi ukusebenza kwiinkqubo zokuvelisa imichiza ezifana nokuthuthwa kwezinto eziphathekayo kunye nokuxuba ukuphendula.
Ivumba: Inevumba elimnandi leziqhamo, elitsha nendalo. Olu phawu lutsale ingqwalasela enkulu kwinkalo yevumba elimnandi, kwaye lunokusetyenziswa njengesixhobo esiphambili sokudibanisa incasa yeziqhamo.
I-Solubility: Inokunyibilika kakuhle kwiintlobo ezininzi ze-solvents eziphilayo, ezifana ne-ethanol, i-ether, i-acetone, njl., okwenza kube lula ukuxuba kunye nokudibanisa nezinye izinto ezixutywayo kwiinkqubo ze-organic synthesis reaction; Ukunyibilika kwamanzi kuncinci, okuhambelana nomthetho wokuchithwa kwezinto eziphilayo kunye nomxholo ophezulu wekhabhoni.
Indawo yokubilisa: Inoluhlu oluthile lokubilisa, olusisiseko esibalulekileyo sokwahlula kunye nemisebenzi yokucoca efana ne-distillation kunye nokulungiswa. Indawo yokubilisa yeesampulu ezinezihlambululo ezahlukeneyo zinokuhluka kancinci, kwaye umgangatho kunye nokucoceka kwemveliso kunokuvavanywa kwangaphambili ngokulinganisa ngokuchanekileyo indawo yokubilisa.
4. Iipropati zeMichiza
I-Acetal hydrolysis reaction: Ngaphantsi kweemeko ze-acidic, isakhiwo se-diethylacetal kwi-molecule sixhomekeke kwi-hydrolysis, ukuvelisa amaqela e-aldehyde kunye ne-ethanol kwakhona. Olu phawu luhlala lusetyenziswa kwi-organic synthesis yokuguqulwa kweqela elisebenzayo okanye ukhuseleko lweqela le-aldehyde, kwaye lukhutshwa ngexesha elifanelekileyo lokuthatha inxaxheba kwiimpendulo ezilandelayo.
Ukusabela kokudibanisa ibhondi ephindwe kabini: Iibhondi zeCarbon carbon kabini zinokusebenza njengeziza ezisebenzayo kwaye zingene kwiimpendulo ezongeziweyo nge-hydrogen, iihalogens, njl. Ngokulawula iimeko zokusabela kunye nedosi ye-reagent, uthotho lwezinto eziphuma kuzo zinokulungiswa ngokukhethayo, zityebisa ukwahluka kweekhompawundi.
Ukusabela kwe-oxidation: Ngaphantsi kwesenzo se-oxidants ezifanelekileyo, iimolekyuli zinokungena kwi-oxidation, i-bond breakage kabini, okanye i-oxidation eyongezelelweyo yamaqela e-aldehyde ukuvelisa iimveliso ze-oxidation ezihambelanayo, ukubonelela indlela yokudibanisa ezinye iikhompawundi ezinzima.
5, Indlela yokudibanisa
Indlela eqhelekileyo yokwenziwa kukuqala nge-trans-2-hexenal kwaye uyiphendule nge-ethanol ye-anhydrous phambi kwee-catalysts ze-acidic ezifana negesi ye-hydrogen chloride eyomileyo, i-p-toluenesulfonic acid, njl. uluhlu lweqondo lokushisa eliphantsi ukuya kwiqondo lokushisa, ukuthintela ukuphendulwa kwecala ukuba kwenzeke; Ngexesha elifanayo, kuyimfuneko ukuqinisekisa indawo engabonakaliyo, njengoko ubukho bamanzi bunokuguqula ukusabela kwe-aldol kwaye kuchaphazele isivuno. Emva kokuba i-reaction igqityiwe, i-catalyst ivame ukungathathi hlangothi kunye nesisombululo se-alkaline, kwaye emva koko ihlukaniswe yi-distillation, ukulungiswa kunye nezinye iindlela zokufumana iimveliso ezijoliswe ekucoceni okuphezulu.
