Taw qhia
2,5-Diaminotoluene yog ib qho organic compound, cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 2,5-diaminotoluene:
Zoo:
- Cov tsos mob: 2,5-Diaminotoluene yog dawb mus rau lub teeb daj crystalline hmoov.
- Solubility: Nws dissolves me ntsis hauv dej, tab sis yog soluble ntau dua hauv cov kuab tshuaj organic xws li benzene thiab cawv-raws li cov kuab tshuaj.
Siv:
- 2,5-Diaminotoluene yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis, uas feem ntau yog siv rau hauv kev npaj cov pigments thiab dyes, tshwj xeeb tshaj yog nyob rau hauv kev npaj ntawm hluavtaws fiber ntau zoo.
Txoj kev:
- Kev npaj ntawm 2,5-diaminotoluene yog ua tiav los ntawm kev txo cov nitrotoluene. Nitrotoluene thawj reacts nrog ammonia los tsim 2,5-dinitrotoluene, uas yog txo mus rau 2,5-diaminotoluene los ntawm ib tug txo tus neeg saib xyuas xws li sodium diene.
Cov ntaub ntawv kev nyab xeeb:
- 2,5-Diaminotoluene ua rau khaus ntawm lub qhov muag thiab tawv nqaij, yog li hnav cov khoom tiv thaiv tsim nyog thiab zam kev sib cuag thaum siv nws.
- Thaum ua haujlwm, tsis txhob nqus nws cov plua plav lossis kev daws teeb meem thiab tswj qhov cua kom zoo.
- 2,5-Diaminotoluene yuav tsum khaws cia kom deb ntawm qhov hluav taws kub thiab oxidizing cov neeg ua haujlwm, thiab muab cia rau hauv qhov chaw qhuav, txias.
- Ua raws li cov txheej txheem ua haujlwm nyab xeeb thiab pov tseg cov pov tseg kom zoo thaum tuav lossis khaws cia.
