Intshayelelo
I-2,6-Dichloro-4-trifluoromethylaniline, eyaziwa ngokuba yi-DCPA, i-organic compound. Oku kulandelayo kukwazisa ngobume, ukusetyenziswa, indlela yokuvelisa kunye nolwazi lokhuseleko lwe-DCPA:
Umgangatho:
- Ayinambala ukuya kwiikristale ezityheli okanye izinto eziqinileyo ezingumgubo.
- I-DCPA ine-volatility ephantsi kwiqondo lokushisa.
- Ayinyibiliki emanzini kwaye ayinyibiliki kangako kwizinyibilikisi zendalo.
Sebenzisa:
- I-DCPA isoloko isetyenziswa njengento ekrwada kwaye iphakathi kwizibulali-zinambuzane.
- Isetyenziswa kakhulu kwezolimo ukulawula ukhula olwahlukeneyo, umngundo, izinambuzane nezifo.
- I-DCPA ingasetyenziswa njenge-stabilizer yokugcina amanzi ukuphucula imveliso yomthombo kunye nokwandisa ubomi bokuphila.
Indlela:
- Zininzi iindlela zokulungiselela i-DCPA, ezinokuthi zenziwe ngokusabela kwe-aniline kunye ne-trifluorocarboxic acid.
- Nyibilikisa i-aniline kwisinyibilikisi sotywala kwaye kancinane wongeze i-trifluoroformic acid.
- Ubushushu bokusabela buhlala bulawulwa ngaphantsi kwe -20 ° C, kwaye ixesha lokuphendula lide.
- Ekupheleni kokuphendula, i-DCPA ifunyenwe ngokumisa kunye nokucoca imveliso.
Ulwazi ngoKhuseleko:
- I-DCPA ithathwa njengekhompawundi enetyhefu ephantsi phantsi kweemeko eziqhelekileyo.
- Nangona kunjalo, kufuneka kuthathelwe ingqalelo ukuyisebenzisa kwaye uyigcine ngobulumko, kwaye ugweme ukudibanisa nolusu, amehlo kunye nomgudu wokuphefumula.
-Iiglavu ezikhuselayo, iigawuni, kunye nezixhobo zokukhusela ukuphefumla kufuneka zinxitywe ngexesha lokusetyenziswa.
Ukuba ufuna ukusebenzisa i-DCPA, yenze phantsi kwesikhokelo sobuchwephesha.
