Tetraphenylphosphonium Bromide CAS 2751-90-8
Tetraphenylphosphonium bromide ndi chothandizira kusamutsa magawo, ndipo kugwiritsidwa ntchito kwake ndi ukadaulo watsopano womwe wapangidwa m'zaka makumi awiri zapitazi. Umagonjetsa vuto lofunikira ma solvents a polar aprotic mu synthesis yachilengedwe yosiyanasiyana, ndipo ungapangitse kuti zochita zosiyanasiyana zichitike pansi pa mikhalidwe yofatsa, motero umafulumizitsa liwiro la reaction ndikukweza zokolola, motero umagwira ntchito yayikulu pakulimbikitsa chitukuko cha synthesis yachilengedwe.

1. Zosakaniza zachilengedwe
Kukonza kusintha kwa gawo (PTC): Monga chothandizira kusintha kwa gawo, chimalimbikitsa kusamutsa ma ion pakati pa gawo lamadzi ndi gawo lachilengedwe, chimakweza kwambiri liwiro ndi kukolola kwa machitidwe osiyanasiyana, ndipo chimagwiritsidwa ntchito kwambiri popanga mankhwala (monga sulfonylation, dehydration reaction) ndi kukonzekera kwapakati kwa mankhwala ophera tizilombo.
Nucleophilic reagent: Imapanga ma ayoni a alkyl bromide, imatenga nawo mbali mu zochita monga acyl substitution ndi etherification, ndipo imapangitsa kuti njira yopangira mamolekyu ovuta ikhale yosavuta (monga utoto ndi ma polymer monomers).
2. Sayansi ya Zipangizo
Electrolyte ya zida zamagetsi: Chifukwa cha mphamvu yake yoyendetsa ma ionic, imagwiritsidwa ntchito ngati electrolyte yothandizira kuchepetsa ma electroreduce a fullerene kuti iwonjezere mphamvu ya mabatire ndi ma supercapacitor.
Chosinthira cha polima: Chimalowetsa maatomu a bromine/phosphorous mu unyolo wa polima monga polyethylene ndi polyvinyl chloride kuti chiwonjezere kukhazikika kwa kutentha, mphamvu ya makina komanso mphamvu zoletsa moto za chinthucho.
3. Kafukufuku ndi chitukuko cha mankhwala
Mankhwala osakaniza: Amatenga nawo mbali mu njira zofunika monga ketone dehydration ndi catalytic hydrogenation, ndipo amagwiritsidwa ntchito popanga mamolekyu a mankhwala oyera kwambiri (monga mankhwala oletsa khansa ndi mankhwala opha mabakiteriya) kuti achepetse ndalama zopangira.
4. Kukonzekera zipangizo zogwirira ntchito
Zoyambira zamadzimadzi a Ionic: Kupanga zakumwa za ionic zomwe zimakhala ndi kusasinthasintha kochepa komanso kukhazikika kwa kutentha kwambiri kuti zigwiritsidwe ntchito mu zosungunulira zobiriwira komanso electrochemical catalysis.
