(n-Butyl) triphenylphosphonium bromide (CAS# 1779-51-7)Tsebeliso le mekhoa ea ho kopanya
Butyltriphenylphosphine bromide ke motsoako oa organophosphorus. E na le ts'ebeliso ea bohlokoa ho organic synthesis, 'me mona ke tse ling tsa ts'ebeliso ea eona e tloaelehileng le mekhoa ea ho kopanya:
Sebelisa:
1. Catalyst: Butyltriphenylphosphine bromide e atisa ho sebelisoa e le mohloli oa liphetoho tse itseng tsa lik'hemik'hale. Mohlala, karabelong ea Friedel-Gram, e ka susumetsa karabelo ea khokahano lipakeng tsa li-alkyne le li-borides ho kopanya li-isomer tsa topological tsa alkynes.
2. Organometallic chemistry: Butyltriphenylphosphine bromide e ka boela ea sebelisoa e le ligand ka k'hemistri ea organometallic. E ka etsa li-complexes tse nang le li-ion tsa tšepe 'me ea kenya letsoho liketsong tse ling tsa bohlokoa tsa organic synthesis, joalo ka karabelo ea Suzuki.
Mokhoa oa ho kopanya:
Ho na le mekhoa e 'maloa ea ho qaptjoa ha butyltriphenylphosphine bromide,' me e latelang ke e 'ngoe ea mekhoa e tloaelehileng:
1. Lisebelisoa tse tala tse sebetsang: bromobenzene, triphenylphosphine, butane bromide;
2. Mehato:
(1) Sebakeng se sa sebetseng hantle, bromobenzene le triphenylphosphine li eketsoa ka har'a botlolo ea ho arabela;
(2) Botlolo ea karabelo e tiisitsoe ebe e hlohlelletsoa tlas'a taolo ea mocheso, 'me mocheso o akaretsang oa karabelo ke likhato tse 60-80 tsa Celsius;
(3) Butane butane bromide ha ho hlokahala 'me u tsoele pele karabelo e susumetsang;
(4) Ka mor'a hore karabelo e phethoe, e pholile ho isa mocheso oa kamore;
(5) Ho ntšoa le ho hlatsoa ka li-solvents, le ho omisa, crystallization le mehato e meng ea phekolo;
(6) Qetellong, sehlahisoa sa butyltriphenylphosphine bromide se fumanoa.
