Taw qhia
3-nitroanisole (3-nitroanisole) yog cov organic compound nrog cov tshuaj formula C7H7NO3. Nws yog ib qho xim tsis muaj xim rau yellowish khoom siv lead ua nrog ib tug peculiar tsw.
3-nitroanisole yog dav siv nyob rau hauv thaj tsam ntawm cov organic synthesis thiab feem ntau yog siv los ua raw khoom thiab nruab nrab rau cov organic synthesis tshuaj. Nws tuaj yeem siv los npaj lwm cov organic sib txuas, xws li fluorescent dyes, tshuaj thiab tshuaj tua kab. Vim tias nws muaj qee yam muaj ntxhiab tsw, nws tuaj yeem siv rau hauv kev sib xyaw ntawm cov txuj lom.
3-nitroanisole tuaj yeem npaj tau los ntawm kev qhia ib pawg nitro hauv anisole. Txoj kev siv feem ntau yog los ua cov tshuaj anisol nrog sodium nitrite nyob rau hauv alkaline tej yam kev mob los tsim 3-nitroanisole. Cov tshuaj tiv thaiv feem ntau yog nqa tawm ntawm chav tsev kub thiab yog nrog los ntawm kev tsim cov dej thiab nitrogen oxide tso tawm.
Thaum siv thiab khaws cia 3-nitroanisole, koj yuav tsum tau xyuam xim rau nws txoj kev nyab xeeb. 3-nitroanisole yog khaus thiab txaus ntshai thiab yuav ua rau khaus ntawm daim tawv nqaij, qhov muag thiab ua pa. Kev sib cuag ncaj qha nrog nws yuav tsum zam. Thaum lub sijhawm ua haujlwm, nws raug nquahu kom hnav cov khoom tiv thaiv tus kheej tsim nyog, xws li hnab looj tes, tsom iav tiv thaiv thiab lub ntsej muag tiv thaiv. Tsis tas li ntawd, 3-Nitroanisole yuav tsum muab cia rau hauv qhov chaw qhuav, txias, zoo-ventilated, deb ntawm hluav taws kub thiab kub. Thaum muab pov tseg, ua raws li cov cai hauv zos.
