Tom ntej: Tetraphenylphosphonium Bromide CAS 2751-90-8
Tetraphenylphosphonium bromide yog ib theem hloov catalyst, thiab nws daim ntawv thov yog ib tug tshiab technology tsim nyob rau hauv ob lub xyoo dhau los. Nws kov yeej qhov tsis zoo ntawm kev xav tau polar aprotic cov kuab tshuaj nyob rau hauv heterogeneous organic synthesis, thiab tuaj yeem ua rau cov tshuaj tiv thaiv heterogeneous tshwm sim nyob rau hauv cov xwm txheej me me, yog li nrawm cov tshuaj tiv thaiv thiab txhim kho cov txiaj ntsig, yog li ua lub luag haujlwm tseem ceeb hauv kev txhawb txoj kev loj hlob ntawm cov organic synthesis.

1. Organic synthesis catalysts
Theem hloov catalysis (PTC): Raws li cov theem hloov pauv hloov pauv tau zoo, nws txhawb kev hloov pauv ion ntawm theem aqueous thiab theem organic, txhim kho tus nqi thiab tawm los ntawm cov tshuaj tiv thaiv heterogeneous, thiab siv dav hauv cov tshuaj synthesis (xws li sulfonylation, lub cev qhuav dej) thiab tshuaj tua kab nruab nrab.
Nucleophilic reagent: Tsim cov alkyl bromide ions, koom nrog kev cuam tshuam xws li acyl hloov pauv thiab etherification, thiab ua kom yooj yim rau kev sib txuas ntawm cov molecules complex (xws li dyes thiab polymer monomers).
2. Khoom siv Science
Electrolyte rau cov khoom siv hluav taws xob: Vim nws cov ionic conductivity siab, nws yog siv los ua ib qho kev txhawb nqa electrolyte rau fullerene electroreduction los txhim kho cov nqi thiab tso tawm efficiency ntawm roj teeb thiab supercapacitors.
Polymer modifier: Qhia txog bromine / phosphorus atoms rau hauv cov saw hlau xws li polyethylene thiab polyvinyl chloride los txhim kho cov thermal stability, mechanical zog thiab nplaim taws retardant khoom ntawm cov khoom.
3. Kev tshawb fawb thiab kev tsim kho tshuaj
Tshuaj intermediates: Koom tes hauv cov kauj ruam tseem ceeb xws li ketone lub cev qhuav dej thiab catalytic hydrogenation, thiab yog siv los tsim cov tshuaj purity siab (xws li cov tshuaj tiv thaiv kab mob thiab tshuaj tua kab mob) kom txo cov nqi tsim khoom.
4. Kev npaj cov khoom siv ua haujlwm
Ionic kua precursors: Synthesis ntawm ionic kua nrog tsawg volatility thiab siab thermal stability rau siv nyob rau hauv ntsuab solvents thiab electrochemical catalysis.
