(n-Butyl) triphenylphosphonium bromide (CAS # 1779-51-7) ojiji na njikọ usoro
Butyltriphenylphosphine bromide bụ ogige organophosphorus. O nwere ngwa dị mkpa na njikọ organic, ebe a bụ ụfọdụ n'ime ojiji ya na ụzọ njikọ ya:
Jiri:
1. Catalyst: Butyltriphenylphosphine bromide na-ejikarị eme ihe dị ka ihe na-eme ka ụfọdụ mmeghachi omume kemịkal. Dịka ọmụmaatụ, na mmeghachi omume Friedel-Gram, ọ nwere ike ime ka mmeghachi omume njikọ dị n'etiti alkynes na borides mebie isomers topological nke alkynes.
2. Organometallic chemistry: Butyltriphenylphosphine bromide nwekwara ike iji dị ka ligand na organometallic chemistry. Ọ nwere ike na-etolite mgbagwoju na metal ion ma sonye na ụfọdụ mkpa organic njikọ mmeghachi omume, dị ka Suzuki mmeghachi omume.
Usoro njikọ:
Enwere ọtụtụ ụzọ maka njikọ nke butyltriphenylphosphine bromide, nke a bụ otu n'ime ụzọ ndị a na-ahụkarị:
1. Mmeghachi omume akụrụngwa: bromobenzene, triphenylphosphine, butane bromide;
2. Nzọụkwụ:
(1) N'ime ikuku na-adịghị mma, a na-agbakwunye bromobenzene na triphenylphosphine na flask mmeghachi omume;
(2) A na-emechi karama mmeghachi omume ma kpalie ya n'okpuru njikwa okpomọkụ, na mmeghachi omume n'ozuzu bụ 60-80 degrees Celsius;
(3) Jiri nwayọọ tinye butane bromide dị ka ọ dị mkpa ma gaa n'ihu na mmeghachi omume na-akpali akpali;
(4) Mgbe emechara mmeghachi omume ahụ, dị jụụ na ụlọ okpomọkụ;
(5) Mwepụta na ịsacha na ihe mgbaze, na ihicha, crystallization na usoro ọgwụgwọ ndị ọzọ;
(6) N'ikpeazụ, a na-enweta ngwaahịa butyltriphenylphosphine bromide.
