Allyltriphenylphosphonium chloride (CAS # 18480-23-4) Kev taw qhia
Allyl triphenylphosphine chloride (TPCl) yog ib qho organic compound. Nws muaj cov khoom nram qab no:
1. Cov tsos: Cov xim tsis muaj xim crystalline.
4. Solubility: TPPCl yog soluble hauv cov organic solvents, xws li ethanol, acetone, dimethylformamide, thiab lwm yam.
Allyl triphenylphosphine chloride yog tsuas yog siv rau cov tshuaj tiv thaiv catalytic hauv cov organic synthesis. Nws yog siv los ua ib qho reagent hauv catalyzing allyl cov tshuaj tiv thaiv los qhia allyl pawg hauv organic synthesis. TPPCl kuj tseem siv tau los ua ib qho allyl reagent rau alkynes thiab thioesters.
Muaj ntau ntau txoj hauv kev los npaj allyl triphenylphosphine chloride:
1. Allyl triphenylphosphine chloride yog tau los ntawm reacting nrog allyl bromide nyob rau hauv lub xub ntiag ntawm sodium carbonate los yog lithium carbonate hydroxide nyob rau hauv ib tug organic hnyav.
2. Ferrous phosphate yog siv los catalyze deoxychlorination, thiab triphenylphosphine reacted nrog hydrogen chloride los ua allyl triphenylphosphine chloride.
1. Allyl triphenylphosphine chloride ua rau khaus thiab yuav tsum tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag.
2. Hnav cov hnab looj tes tiv thaiv thiab tsom iav thaum ua haujlwm.
3. Tsis txhob nqus nws cov vapors lossis pos huab thiab ua haujlwm hauv qhov chaw muaj cua zoo.
4. Khaws kom deb ntawm hluav taws thiab oxidants thaum khaws cia.
5. Thaum siv thiab khaws cia, thov ua raws li cov txheej txheem kev nyab xeeb ntawm cov tshuaj muaj feem xyuam.
