(n-Butyl) triphenylphosphonium bromide (CAS# 1779-51-7)Kagwiritsidwe ndi kaphatikizidwe njira
Butyltriphenylphosphine bromide ndi gulu la organophosphorus. Imagwiritsidwa ntchito mofunikira pakuphatikizika kwachilengedwe, ndipo nazi zina mwazomwe zimagwiritsidwa ntchito ndi njira zophatikizira:
Gwiritsani ntchito:
1. Chothandizira: Butyltriphenylphosphine bromide imagwiritsidwa ntchito ngati chothandizira pakusintha kwamankhwala. Mwachitsanzo, mu Friedel-Gram reaction, imatha kuyambitsa kulumikizana pakati pa alkynes ndi borides kuti apange ma isomers apamwamba a alkynes.
2. Organometallic chemistry: Butyltriphenylphosphine bromide ingagwiritsidwenso ntchito ngati ligand mu organometallic chemistry. Ikhoza kupanga ma complexes okhala ndi ayoni zitsulo ndikuchita nawo zinthu zina zofunika kwambiri za kaphatikizidwe ka organic, monga Suzuki reaction.
Njira Yophatikizira:
Pali njira zingapo zopangira bromide ya butyltriphenylphosphine, ndipo iyi ndi imodzi mwa njira zodziwika bwino:
1. Zopangira zopangira: bromobenzene, triphenylphosphine, butane bromide;
2. Njira:
(1) M'mlengalenga, bromobenzene ndi triphenylphosphine zimawonjezedwa ku botolo lamadzi;
(2) Botolo lazomwe limasindikizidwa ndikugwedezeka pansi pa kutentha, ndipo kutentha kwakukulu ndi madigiri 60-80 Celsius;
(3) Pang'onopang'ono onjezerani butane bromide ngati pakufunika ndikupitiriza kuchitapo kanthu kugwedeza;
(4) Zomwezo zikatha, zimazizira mpaka kutentha;
(5) M'zigawo ndi kutsuka ndi zosungunulira, ndi kuyanika, crystallization ndi masitepe mankhwala;
(6) Pomaliza, mankhwala a butyltriphenylphosphine bromide amapezeka.
