trans-2-Hexen-1-Al Diethyl Acetal(I-CAS#54306-00-2) ethula
impahla ebonakalayo
Ukubukeka: Ngokuvamile kubonakala njengoketshezi olukhanyayo olungenambala ukuya kokuphuzi olukhanyayo, okwenza kube lula kakhulu ukusebenza ezinqubweni zokukhiqiza amakhemikhali njengokuthuthwa kwezinto ezibonakalayo kanye nokuxutshwa kokusabela.
Iphunga: Inephunga eliyingqayizivele lezithelo, elihlanzekile futhi lemvelo. Lesi sici sidonse ukunaka okukhulu emkhakheni wephunga elimnandi, futhi singasetshenziswa njengezinto ezingavuthiwe eziyinhloko zokuhlanganisa ukunambitheka kwezithelo.
I-Solubility: Ingancibilika kahle kuma-solvents amaningi e-organic, njenge-ethanol, i-ether, i-acetone, njll., okwenza kube lula ukuxuba nokuxhumana namanye ama-reactants ezinhlelweni zokusabela kwe-organic synthesis; Ukuncibilika emanzini kulinganiselwe, okuhambisana nomthetho wokuhlakazwa kwezinhlanganisela zezinto eziphilayo ezinokuqukethwe kwekhabhoni ephezulu.
Indawo yokubilisa: Inebanga elithile lamaphuzu abilayo, okuyisisekelo esibalulekile sokuhlukanisa kanye nemisebenzi yokuhlanza efana nokucwiliswa kwe-distillation nokulungisa. Iphuzu lokubilisa lamasampula anama-purities ahlukene lingahluka kancane, futhi ikhwalithi nokuhlanzeka komkhiqizo kungahlolwa kuqala ngokulinganisa ngokunembile iphuzu lokubilisa.
4, izakhiwo Chemical
Ukusabela kwe-acetal hydrolysis: Ngaphansi kwezimo ezine-acidic, isakhiwo se-diethylacetal ku-molecule sithambekele ku-hydrolysis, sikhiqize amaqembu e-aldehyde kanye ne-ethanol futhi. Lesi sici sivame ukusetshenziswa ku-organic synthesis yokuguqulwa kweqembu elisebenzayo noma ukuvikelwa kweqembu le-aldehyde, futhi sikhishwa ngesikhathi esifanele ukuze sibambe iqhaza ekuphenduleni okulandelayo.
Ukusabela kokwengezwa kwebhondi ekabili: Amabhondi ekhabhoni ekhabhoni ephindwe kabili angasebenza njengamasayithi asebenzayo futhi abhekane nokungezwani kwe-hydrogen, ama-halogen, njll. Ngokulawula izimo zokusabela kanye nomthamo we-reagent, uchungechunge lokuphuma kokunye lungalungiselelwa ngokukhetha, lunothise ukuhlukahluka kwezinhlanganisela.
Ukusabela kwe-oxidation: Ngaphansi kwesenzo sama-oxidants afanelekile, ama-molecule angakwazi ukungena kwi-oxidation, ukuphuka kwebhondi ephindwe kabili, noma okunye ukukhishwa kwe-oxidation kwamaqembu e-aldehyde ukuze akhiqize imikhiqizo ehambisanayo ye-oxidation, ehlinzeka indlela yokuhlanganiswa kwezinye izinhlanganisela eziyinkimbinkimbi.
5. Indlela yokuhlanganisa
Indlela evamile yokwenziwa iwukuqala nge-trans-2-hexenal bese isabela nge-ethanol anhydrous lapho kukhona izinto ezine-acidic ezifana negesi eyomile ye-hydrogen chloride, i-p-toluenesulfonic acid, njll. Inqubo yokusabela idinga ukulawula okuqinile kwezinga lokushisa, ngokuvamile ku ububanzi bokushisa okuphansi kuya ekamelweni lokushisa, ukuvimbela ukusabela okuhlangene ukuthi kungenzeki; Ngesikhathi esifanayo, kuyadingeka ukuqinisekisa imvelo engenamanzi, njengoba ukuba khona kwamanzi kungahlehlisa ukusabela kwe-aldol futhi kuthinte isivuno. Ngemuva kokuthi ukusabela sekuqediwe, i-catalyst ivame ukungathathi hlangothi ngesisombululo se-alkali, bese ihlukaniswa yi-distillation, ukulungiswa nezinye izindlela zokuthola imikhiqizo ehlosiwe ephezulu.
