(n-Butyl) triphenylphosphonium bromide (CAS# 1779-51-7) Isticmaalka iyo hababka isku dhafan
Butyltriphenylphosphine bromide waa unug organophosphorus ah. Waxay leedahay codsiyo muhiim ah oo ku jira isku-dhafka dabiiciga ah, waana kuwan qaar ka mid ah isticmaalkeeda caadiga ah iyo hababka isku-dhafka:
Isticmaal:
1. Catalyst: Butyltriphenylphosphine bromide waxaa badanaa loo isticmaalaa kicinta falcelinta kiimikada qaarkood. Tusaale ahaan, falcelinta Friedel-Gram, waxay kicin kartaa falcelinta isku xidhka ee alkynes iyo borides si ay u abuurto isomers topological alkynes.
2. Organometallic chemistry: Butyltriphenylphosphine bromide waxa kale oo loo isticmaali karaa ligand ahaan kimistariga organometallic. Waxay samayn kartaa dhismayaal leh ion bir ah waxayna ka qaybqaadan kartaa qaar ka mid ah falcelinta synthesis organic ee muhiimka ah, sida falcelinta Suzuki.
Habka isku-dhafka:
Waxaa jira dhowr habab oo loogu talagalay isku dhafka butyltriphenylphosphine bromide, kuwan soo socdaa waa mid ka mid ah hababka caadiga ah:
1. falcelinta alaabta ceeriin: bromobenzene, triphenylphosphine, butane bromide;
2. Tallaabooyinka:
(1) Jawi aan firfircoonayn, bromobenzene iyo triphenylphosphine ayaa lagu daraa weelka falcelinta;
(2) Dhalada falcelinta waa la xidhay oo lagu walaaqay xakamaynta heerkulka, iyo heerkulka falcelinta guud waa 60-80 darajo Celsius;
(3) Si tartiib ah ugu dar butane bromide sida loo baahdo oo sii wad kicinta falcelinta;
(4) Ka dib marka falcelinta la dhammeeyo, qabooji heerkulka qolka;
(5) Soo saarista iyo ku dhaqidda dareeraha, iyo qalajinta, crystallization iyo tallaabooyinka kale ee daaweynta;
(6) Ugu dambeyntii, badeecada bromide butyltriphenylphosphine ayaa la helay.
