Taw qhia
1-Iodo-3-nitrobenzene, tseem hu ua 3-nitro-1-iodobenzene, 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 1-iodo-3-nitrobenzene:
Zoo:
- Cov tsos mob: 1-iodo-3-nitrobenzene yog cov xim daj lossis crystalline hmoov.
- Solubility: 1-Iodo-3-nitrobenzene yog me ntsis soluble hauv ethanol, acetone, thiab chloroform, thiab yuav luag insoluble hauv dej.
Siv:
- Kev siv tshuaj lom neeg: 1-iodo-3-nitrobenzene tuaj yeem siv los ua ke rau lwm cov organic tebchaw, xws li aromatic amines.
- Cov tshuaj tua kab nruab nrab: Nws tuaj yeem siv los ua cov tshuaj tua kab nruab nrab los tsim cov tshuaj tua kab, tshuaj tua kab thiab lwm yam tshuaj tua kab.
Txoj kev:
Txoj kev npaj ntawm 1-iodo-3-nitrobenzene tuaj yeem siv 3-nitrobenzene ua raw khoom thiab ua los ntawm iodization cov tshuaj tiv thaiv. Ib txoj kev npaj ntau yog kom yaj 3-nitrobenzene thiab iodine hauv sodium hydroxide tov nyob rau hauv lub xub ntiag ntawm sodium carbonate, ces maj mam ntxiv chloroform rau cov tshuaj tiv thaiv, thiab thaum kawg kho nrog dilute hydrochloric acid kom tau 1-iodo-3-nitrobenzene.
Cov ntaub ntawv kev nyab xeeb:
1-iodo-3-nitrobenzene yog cov tshuaj lom neeg uas tsim kev puas tsuaj rau tib neeg lub cev thiab ib puag ncig.
- Zam kev sib cuag: kev sib cuag ntawm daim tawv nqaij, qhov muag pom, thiab nqus cov plua plav lossis roj ntawm 1-iodo-3-nitrobenzene yuav tsum zam.
- Kev tiv thaiv: Hnav cov khoom tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab qhov ncauj qhov ntswg thaum ua haujlwm.
- Qhov cua qhov cua: Nws yog ib qho tseem ceeb los xyuas kom meej tias qhov chaw ua haujlwm yog qhov cua zoo kom txo tau cov concentration ntawm cov pa phem.
- Cia thiab tuav: Nws yuav tsum muab cia rau hauv lub thawv airtight, kom deb ntawm hluav taws kub thiab kub. Cov khib nyiab yuav tsum tau muab pov tseg raws li cov kev cai cuam tshuam.
1-Iodo-3-nitrobenzene yog qhov txaus ntshai, thiab cov lus qhia kev nyab xeeb ntawm cov tshuaj muaj feem xyuam yuav tsum tau ua tib zoo nyeem thiab ua raws li ua ntej siv.
