(n-Butyl)triphenylphosphonium bromide (CAS# 1779-51-7)Ukusetshenziswa nezindlela zokuhlanganisa
I-Butyltriphenylphosphine bromide iyinhlanganisela ye-organophosphorus. Inezinhlelo zokusebenza ezibalulekile ku-organic synthesis, futhi nazi ezinye zezindlela ezivamile zokusetshenziswa nezindlela zokuhlanganisa:
Sebenzisa:
1. I-Catalyst: I-Butyltriphenylphosphine bromide ivame ukusetshenziswa njenge-catalyst yokusabela okuthile kwamakhemikhali. Isibonelo, ekuphenduleni kwe-Friedel-Gram, ingadala ukuhlangana kokuhlangana phakathi kwama-alkynes nama-borides ukuze kuhlanganiswe ama-isomers we-topological of alkynes.
2. Ikhemikhali ye-Organometallic: I-Butyltriphenylphosphine bromide ingasetshenziswa futhi njenge-ligand kukhemistri ye-organometallic. Ingakha ama-complexes ngama-ion ensimbi futhi ibambe iqhaza kokunye okubalulekile kokusabela kwe-organic synthesis, njengokusabela kwe-Suzuki.
Indlela Yokuhlanganisa:
Kunezindlela eziningana zokwenziwa kwe-butyltriphenylphosphine bromide, futhi okulandelayo kungenye yezindlela ezijwayelekile:
1. Izinto ezingasetshenzisiwe: i-bromobenzene, i-triphenylphosphine, i-butane bromide;
2. Izinyathelo:
(1) Emkhathini ongasebenzi, i-bromobenzene ne-triphenylphosphine yengezwa kufulaski wokusabela;
(2) Ibhodlela lokusabela liyavalwa futhi linyakaziswa ngaphansi kokulawulwa kwezinga lokushisa, futhi izinga lokushisa elivamile lokusabela lingama-60-80 degrees Celsius;
(3) Yengeza kancane kancane i-butane bromide njengoba kudingeka futhi uqhubeke nokunyakazisa ukusabela;
(4) Ngemva kokuba ukusabela kuqediwe, kuphole kuya ekamelweni lokushisa;
(5) Ukukhipha nokugeza ngezincibilikisi, nokomisa, ukucwebezela kanye nezinye izinyathelo zokwelapha;
(6) Ekugcineni, kutholakala umkhiqizo we-butyltriphenylphosphine bromide.
