1,8-Diazabicyclo[5.4.0]undec-7-ene CAS:6674-22-2

1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) e na le lits'ebetso tse fapaneng mafapheng a fapaneng a saense, haholo-holo k'hemistri ea lintho tse phelang, meriana le saense ea polymer. E 'ngoe ea ts'ebeliso ea eona ea mantlha ke motheo o sebetsang hantle haholo liketsong tsa tlhahiso ea lik'hemik'hale tse kenyelletsang ho tlosoa ha protonation, condensation le lits'ebetso tsa ho felisoa. Motheo o matla oa DBU le nucleophilicity li etsa hore e be sesebelisoa sa bohlokoa sa ho khothaletsa liphetoho tse fapaneng ka khetho e phahameng le katleho. Ntle le karolo ea eona e le reagent e feto-fetohang ho tsoakong ea lintho tse phelang, DBU e sebelisoa k'hemistring ea meriana le ho sibolloa ha lithethefatsi ho nolofatsa ho lokisoa ha metsoako ea meriana le metsoako e sebetsang. Ho kenella ha eona mehatong ea bohlokoa ea maiketsetso ho nolofalletsa tlhahiso ea limolek'hule tse rarahaneng tse nang le bokhoni ba kalafo, ho kenya letsoho nts'etsopele ea meriana e mecha le baemeli ba meriana bakeng sa ho phekola mafu. Ho feta moo, motsoako ona o sebetsa e le karolo ea bohlokoa liketsong tsa polymerization, haholo-holo tlhahisong ea polyurethanes le lisebelisoa tse ling tsa polymer. Bokhoni ba DBU ba ho susumetsa lits'ebetso tsa polycondensation le ho khothaletsa ho hokahanya ha polymer ho ntlafatsa thepa ea polymer, joalo ka matla a mechini, botsitso ba mocheso, le litšobotsi tsa ho khomarela, e leng se lebisang ho thehoeng ha thepa e tsoetseng pele bakeng sa lits'ebetso tsa indasteri le tsa khoebo. Ho feta moo, DBU e sebelisoa lipatlisisong tsa thuto ho batlisisa likarabelo tsa tlhaho, litsela tsa mechini, le likamano tsa sebopeho le mosebetsi litsamaisong tsa lik'hemik'hale. Bo-rasaense ba hlahloba reactivity le khetho ea DBU maemong a fapaneng a maiketsetso ho hlakisa mekhoa ea karabelo, ho ntlafatsa maemo a karabelo, le ho sibolla maano a macha a ho kopanya metsoako le thepa ea bohlokoa. Ka kakaretso, 1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) e bapala karolo ea bohlokoa ho kopanyeng lintho tse phelang, nts'etsopele ea meriana, k'hemistri ea polymer, le boiteko ba mantlha ba lipatlisiso. Thepa ea eona e ikhethang, bokhoni ba catalytic, le ts'ebeliso e pharaletseng li etsa hore e be sesebelisoa sa bohlokoa bakeng sa ho ntšetsa pele tsebo ea saense, boqapi ba theknoloji, le lits'ebetso tse sebetsang masimong a fapaneng a k'hemistri le saense ea thepa.
