3,5-Dimethyl-4-nitrobenzoic acid(CAS#3095-38-3)
| Zizindikiro Zowopsa | 36/37/38 - Zokwiyitsa maso, kupuma komanso khungu. |
| Kufotokozera Zachitetezo | S26 - Mukakhudza maso, yambani nthawi yomweyo ndi madzi ambiri ndikupempha uphungu wachipatala. S36 - Valani zovala zoyenera zodzitetezera. |
Mawu Oyamba
4-Nitro-3,5-dimethylbenzoic acid ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:
Ubwino:
- 4-Nitro-3,5-dimethylbenzoic acid ndi kristalo wopanda mtundu wolimba komanso wonunkhira.
- Imakhala yosasunthika kutentha, koma kuphulika kumatha kuchitika pa kutentha kwakukulu, pakuwala, kapena poyatsidwa ndi magwero.
- Imakhala pafupifupi yosasungunuka m'madzi, koma imasungunuka mu zosungunulira zachilengedwe monga ethanol, ethers, ndi ma chlorinated hydrocarbons.
Gwiritsani ntchito:
- 4-nitro-3,5-dimethylbenzoic acid amagwiritsidwa ntchito makamaka ngati utoto wapakatikati ndi zinthu zopangira kupanga ma pigment.
Njira:
- 4-Nitro-3,5-dimethylbenzoic acid imatha kupezeka ndi nitrification wa p-toluene. Nitrification reaction imagwiritsa ntchito kusakaniza kwa nitric acid ndi sulfuric acid ngati mankhwala opangira nitrifying.
- Njira yeniyeni yokonzekera nthawi zambiri ndi: toluene imasakanizidwa ndi nitric acid ndi sulfuric acid, imatenthedwa kuti ichitike, kenako imayeretsedwa ndi kuyeretsedwa.
Zambiri Zachitetezo:
- 4-Nitro-3,5-dimethylbenzoic acid imakwiyitsa komanso ikuwononga ndipo iyenera kupewedwa pokhudzana ndi khungu ndi maso.
- Pogwira ntchito imeneyi, valani magolovesi oteteza, zopumira, ndi magalasi oteteza kuti musapume mpweya kapena kukhudzana ndi khungu.
- Posunga ndikugwira, pewani kukhudzana ndi zotsekemera, zoyatsira ndi zinthu zoyaka moto kuti mupewe moto kapena kuphulika.
- Mukalowetsedwa mwangozi kapena kupumira mpweya, funsani thandizo lachipatala nthawi yomweyo ndikuwonetsa chikalata chachitetezo chamankhwala kwa dokotala wanu.
