Isingeniso
I-Methyl trifluoromethylbenzoate. Okulandelayo yisethulo sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha kwenhlanganisela:
Ikhwalithi:
Ukubukeka: I-Methyl trifluoromethylbenzoate iwuketshezi olungenambala futhi olusobala.
Ukunyibilika: Kuncibilika kuzincibilikisi eziningi eziphilayo njenge-ethanol, i-dimethylformamide, ne-chloroform.
Ukuqina kokushisa okuphezulu: kuzinzile emazingeni okushisa aphezulu, akulula ukubola.
Sebenzisa:
I-Methyl trifluoromethylbenzoate ivamise ukusetshenziswa njengenhlanganisela ebalulekile emaphakathi ku-organic synthesis.
Ingasetshenziswa futhi ukwenza izithasiselo kuma-polymers nama-coatings.
Inomphumela okhuthazayo ezitshalweni, futhi isetshenziswa nasensimini yezolimo.
Indlela:
I-Methyl trifluoromethylbenzoate yenziwa ngokuyinhloko yi-fluorination ye-methyl benzoate ne-trifluorocarboxylic acid. Le nqubo ivame ukwenziwa ekushiseni okuphansi ukuze kugwenywe ukuvela kokusabela ohlangothini. Ngemuva kokusabela, umkhiqizo ohlanzekile utholakala ngenqubo ye-distillation nokuhlanza.
Ulwazi Lokuphepha:
I-Methyl trifluoromethylbenzoate iwuketshezi oluvuthayo futhi kufanele igcinwe kude namalangabi avulekile kanye namazinga okushisa aphezulu.
Ukuthinta isikhumba namehlo kungase kubangele ukucasuka, futhi kufanele kuqashelwe ukusebenzisa izinto zokuzivikela ezifana namagilavu nezibuko.
Gwema ukuthintana nama-oxidants nama-asidi aqinile ngesikhathi sokusetshenziswa nokugcinwa ukuze uvimbele ukwenzeka kokusabela okuyingozi.
Ukulahlwa kwemfucuza kufanele kuhambisane nemithetho nemithetho yendawo, futhi akufanele ilahlwe ngokuthanda kwakho.
Ngokuvamile, i-methyl trifluoromethylbenzoate iyinhlanganisela ebalulekile ephakathi, esetshenziswa kakhulu emikhakheni yezemithi, yamakhemikhali nezolimo. Ngesikhathi sokusetshenziswa, ukunakwa kufanele kukhokhwe ekusebenzeni okuphephile ukugwema ukusabela okungekuhle nezinye izinto zamakhemikhali.
