Nhanganyaya
2,6-Dichloro-4-trifluoromethylaniline, inozivikanwawo seDCPA, is an organic compound. Iyi inotevera sumo kune chimiro, kushandiswa, kugadzira nzira uye ruzivo rwekuchengetedza kweDCPA:
Hunhu:
- Haina ruvara kune yero makristasi kana huturu hwehupfu.
- DCPA ine yakaderera volatility pakamuri tembiricha.
-Haisi kunyungudika mumvura uye inonyungudika muorganic solvents.
Shandisa:
- DCPA inowanzo shandiswa sechinhu chakabikwa uye chepakati chemishonga yezvipembenene.
- Inoshandiswa zvakanyanya mukurima kudzora masora akasiyana siyana, fungi, uye zvipembenene nezvirwere.
- DCPA inogona zvakare kushandiswa sereservoir stabilizer kuvandudza kugadzirwa kwematsime uye kuwedzera hupenyu hwakanaka.
Nzira:
- Kune dzakawanda nzira dzekugadzirira dzeDCPA, dzinogona kugadzirwa nekuita kweaniline uye trifluorocarboxic acid.
- Dissolve aniline mune doro solvent uye zvishoma nezvishoma wedzera trifluoroformic acid.
- The reaction tembiricha rinowanzodzorwa pazasi -20 ° C, uye kuita nguva refu.
- Pakupera kwekuita, DCPA inowanikwa nekuomesa uye kuchenesa chigadzirwa.
Zvekuchengetedza
- DCPA inoonekwa seyakaderera-chepfu musanganiswa pasi pemamiriro ezvinhu.
- Zvisinei, kutarisirwa kunofanira kuramba kutorwa kuti ushandise uye uichengetedze nehungwaru, uye udzivise kusangana neganda, maziso uye nzira yekufema.
-Magurovhosi ekudzivirira, machira, uye zvekudzivirira zvekufema zvinofanirwa kupfekwa panguva yekushandiswa.
Kana uchida kushandisa DCPA, ita uchitungamirirwa nenyanzvi.
