Taw qhia
N-phenyl-N-nitroso-p-toluenesulfonamide (BTd luv luv) yog cov organic compound. Cov hauv qab no yog kev qhia txog qee yam ntawm nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Khoom: BTd yog xim tsis muaj xim rau lub teeb daj crystalline khoom nrog qee qhov solubility.
Nws tuaj yeem siv rau hauv kev sib txuas ntawm lwm cov organic sib txuas xws li aniline, pyrroles, thiab thiophene derivatives.
Txoj kev: Txoj kev dav dav ntawm kev npaj BTd yog tau los ntawm reacting p-toluenesulfonamide nrog nitrous acid. Txoj kev npaj tshwj xeeb tuaj yeem ua rau yaj p-toluenesulfonamide hauv dilute sulfuric acid, thiab tom qab ntawd ntxiv nitrite rau cov tshuaj tiv thaiv hauv kev poob qis, thaum ua kom cov tshuaj tiv thaiv kub qis dua 5 degrees Celsius. Tom qab cov tshuaj tiv thaiv tiav, BTd cov khoom yog txias, crystallized thiab lim.
Cov Ntaub Ntawv Kev Nyab Xeeb: Kev siv thiab kev ua haujlwm ntawm BTd yuav tsum tau ua nrog cov txheej txheem kev nyab xeeb tsim nyog. Nws yog ib qho organic compound uas tuaj yeem ua rau qee yam khaus thiab lom. Thaum tuav thiab kov BTd, yuav tsum tau siv cov kev ceev faj tsim nyog xws li hnav cov hnab looj tes tiv thaiv thiab tsom iav, thiab yuav tsum tau ua kom muaj qhov chaw ua haujlwm zoo. Kev sib cuag nrog lwm cov organics thiab oxidants yuav tsum zam kom tsis txhob muaj kev phom sij txaus ntshai. Nyob rau hauv cov ntaub ntawv ntawm kev nqus pa, hu rau ntawm daim tawv nqaij, los yog kev huam yuaj ntawm BTd, nrhiav kev kho mob tam sim ntawd thiab muab cov ntaub ntawv tsim nyog cov ntaub ntawv kev nyab xeeb.
