Taw qhia
N-Ethyl-p-toluenesulfonamide yog ib qho organic compound.
Zoo:
N-ethyl p-toluenesulfonamide yog cov khoom nyob rau hauv chav tsev kub, soluble nyob rau hauv ib co organic solvents xws li cawv thiab ethers, thiab insoluble nyob rau hauv dej. Nws yog ib tug nruab nrab compound uas yog insensitive rau ob qho tib si acids thiab bases.
Siv:
N-ethyl p-toluenesulfonamide feem ntau yog siv los ua cov kuab tshuaj thiab catalyst hauv cov organic synthesis. Nws tuaj yeem siv rau hauv cov tshuaj sib xyaw ua ke xws li cov tshuaj tiv thaiv oxidation, cov tshuaj tiv thaiv acylation, cov tshuaj tiv thaiv amination, thiab lwm yam.
Txoj kev:
Kev npaj ntawm N-ethyl p-toluenesulfonamide tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm p-toluenesulfonamide nrog ethanol nyob rau hauv alkaline tej yam kev mob. Ua ntej, p-toluenesulfonamide thiab ethanol yog ntxiv rau cov tshuaj tiv thaiv hlab ntsha, ib qho nyiaj ntawm alkali catalyst yog ntxiv thiab cov tshuaj tiv thaiv yog rhuab, thiab tom qab cov tshuaj tiv thaiv tiav, cov khoom yog tau los ntawm txias thiab crystallization.
Cov Lus Qhia Txog Kev Nyab Xeeb: Tsis txhob sib cuag nrog daim tawv nqaij, qhov muag, thiab nqus pa, thiab siv hnab looj tes tiv thaiv, tsom iav, thiab qhov ncauj qhov ntswg. Khaws kom deb ntawm qhov hluav taws kub thiab oxidants thaum siv thiab khaws cia kom tsis txhob hlawv thiab tawg. Cov khib nyiab yuav tsum muab pov tseg raws li cov cai hauv zos.
