Taw qhia
2-nitroanisole, tseem hu ua 2-nitrophenoxymethane, yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 2-nitroanisole:
Zoo:
2-Nitroanisole yog cov xim tsis muaj xim lossis daj daj nrog cov tswm ciab tshwj xeeb tswm ciab. Nyob rau hauv chav tsev kub, nws tuaj yeem ruaj khov hauv huab cua. Nws yog soluble hauv cov kuab tshuaj organic xws li ethanol, ether, thiab chloroform, tab sis insoluble hauv dej.
Siv:
2-nitroanisole feem ntau yog siv los ua tshuaj reagent hauv cov organic synthesis cov tshuaj tiv thaiv. Nws tuaj yeem siv los ua cov khoom sib txuas nruab nrab ntawm cov tshuaj tsw qab rau kev npaj ntawm lwm cov tebchaw. Nws muaj cov ntxhiab tsw tshwj xeeb ntawm cov tswm ciab haus luam yeeb thiab tseem siv los ua cov khoom xyaw hauv cov txuj lom.
Txoj kev:
Kev npaj ntawm 2-nitroanisole feem ntau tau txais los ntawm cov tshuaj tiv thaiv ntawm anisol nrog nitric acid. Txoj kev npaj tshwj xeeb yog raws li hauv qab no:
1. Dissolve anisol hauv anhydrous ether.
2. Maj mam ntxiv nitric acid dropwise rau cov tshuaj, khaws cov tshuaj tiv thaiv kub ntawm 0-5 ° C, thiab do tib lub sijhawm.
3. Tom qab cov tshuaj tiv thaiv, cov ntsev inorganic hauv cov tshuaj raug cais los ntawm kev pom.
4. Ntxuav thiab qhuav cov organic theem nrog dej thiab ces purify nws los ntawm distillation.
Cov ntaub ntawv kev nyab xeeb:
2-Nitoanisole muaj qhov ua rau khaus ntawm qhov muag, tawv nqaij, thiab ua pa ib ntsuj av tau thiab tuaj yeem ua rau khaus, mob, thiab kub hnyiab. Cov cuab yeej tiv thaiv tus kheej tsim nyog xws li tsom iav tshuaj tiv thaiv, hnab looj tes, thiab khaub ncaws tiv thaiv yuav tsum hnav thaum siv lossis npaj. Nws yog tawg thiab yuav tsum tau zam los ntawm kev sib cuag nrog cov khoom siv hluav taws xob, qhib nplaim taws thiab qhov chaw kub kub. Yog tias cov tshuaj nqus tau los yog nqus tau, yuav tsum tau nrhiav kev kho mob tam sim ntawd.
