Isingeniso
I-2,6-Dichloro-4-trifluoromethylaniline, eyaziwa nangokuthi i-DCPA, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo, ukusetshenziswa, indlela yokukhiqiza kanye nolwazi lokuphepha lwe-DCPA:
Ikhwalithi:
- Ayinambala ukuya kumakristalu aphuzi noma okuqinile okuyimpuphu.
- I-DCPA inokuguquguquka okuphansi ekamelweni lokushisa.
- Ayincibiliki emanzini futhi incibilika kuma-organic solvents.
Sebenzisa:
- I-DCPA ivame ukusetshenziswa njengempahla eluhlaza futhi emaphakathi yezibulala-zinambuzane.
- Isetshenziswa kabanzi kwezolimo ukulawula ukhula oluhlukahlukene, isikhunta, nezinambuzane nezifo.
- I-DCPA ingasetshenziswa futhi njengendawo yokugcina amanzi ukuze kuthuthukiswe ukukhiqizwa kwemithombo nokwelula impilo yemithombo.
Indlela:
- Ziningi izindlela zokulungiselela i-DCPA, ezingahlanganiswa ngokusabela kwe-aniline ne-trifluorocarboxic acid.
- Chaza i-aniline kusincibilikisi sotshwala bese wengeza kancane i-trifluoroformic acid.
- Izinga lokushisa lokusabela livame ukulawulwa ngaphansi kuka -20 ° C, futhi isikhathi sokusabela side.
- Ekupheleni kokusabela, i-DCPA itholwa ngokomisa nokuhlanza umkhiqizo.
Ulwazi Lokuphepha:
- I-DCPA ibhekwa njengenhlanganisela yobuthi obuphansi ngaphansi kwezimo ezijwayelekile.
- Kodwa-ke, kufanele kuqashelwe ukuthi uyisebenzise futhi uyigcine ngokuhlakanipha, futhi ugweme ukuthinta isikhumba, amehlo kanye nomgudu wokuphefumula.
- Amagilavu okuzivikela, izingubo zokugqoka, nemishini yokuvikela ukuphefumula kufanele kugqokwe ngesikhathi sokusetshenziswa.
Uma udinga ukusebenzisa i-DCPA, kwenze ngaphansi kokuqondisa kochwepheshe.
