Taw qhia
2,4-Dinitroaniline yog ib qho organic compound. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- 2,4-Dinitroaniline yog daj crystalline hmoov uas yog insoluble hauv dej.
- Nws muaj qhov taw tes siab kub kub thiab tawg, thiab raug cais raws li tawg.
- Nws tuaj yeem txo qis rau amine compounds los ntawm cov hauv paus muaj zog thiab hydroxides.
Siv:
- 2,4-Dinitroaniline yog dav siv nyob rau hauv kev lag luam chemical ua raw khoom rau explosives thiab explosives.
- Nws kuj tuaj yeem siv rau hauv kev sib txuas ntawm dyes thiab pigments, nrog rau qhov tseem ceeb nruab nrab.
Txoj kev:
- Kev npaj ntawm 2,4-dinitroaniline feem ntau yog ua los ntawm nitrification. p-nitroaniline reacts nrog concentrated nitric acid rau daim ntawv 2,4-dinitronitroaniline, thiab ces txo cov compound nrog muaj zog acid kom tau 2,4-dinitroaniline.
Cov ntaub ntawv kev nyab xeeb:
- 2,4-Dinitroaniline yog cov tshuaj lom neeg tawg heev thiab yuav tsum tau khaws cia kom deb ntawm cov nplaim taws thiab qhov chaw kub.
- Qhov kev pheej hmoo ntawm kev sib txhuam, kev cuam tshuam, sparks, thiab electrostatic paug yuav tsum tau tswj nruj me ntsis thaum tuav, khaws cia, thiab kev thauj mus los.
- Hnav cov khoom tiv thaiv tus kheej tsim nyog xws li tsom iav kev nyab xeeb thiab hnab looj tes tiv thaiv thaum siv. Yog tias noj, nrhiav kev kho mob tam sim ntawd.
Ib txwm ua raws li cov txheej txheem kev nyab xeeb thaum siv thiab tuav 2,4-dinitroaniline, thiab siv nrog kev paub thiab kev ceev faj kom tsim nyog.
