4-Bromo-3-fluorobenzotrifluoride (CAS# 40161-54-4)
| Amakhodi Engozi | R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. R51 – Kunobuthi ezintweni eziphila emanzini R36 – Ukucasuka emehlweni R38 – Ukucasuka esikhunjeni R37 – Ukucasula uhlelo lokuphefumula |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S36 – Gqoka izingubo ezifanele zokuzivikela. S37 – Gqoka amagilavu afanelekile. |
| Ikhodi ye-HS | 29039990 |
| I-Hazard Class | I-IRRITANT |
Isingeniso
iyinhlanganisela yemvelo, ifomula yamakhemikhali ye-C7H3BrF4, ukubukeka kwayo kuwuketshezi oluphuzi olungenambala noma olukhanyayo. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
-Ukuminyana: cishe. 1.894g/cm³
-Indawo yokuncibilika: cishe -23°C
-Indawo yokubilisa: mayelana ne-166-168°C
-I-Solubility: Incibilika kuma-solvents avamile, njenge-ethanol, i-dimethylformamide ne-dichloromethane.
Sebenzisa:
Isetshenziswa kakhulu emkhakheni we-organic synthesis njengento eluhlaza yokuhlanganiswa kwezinhlobonhlobo zezidakamizwa neziphakathi. Ivame ukusetshenziswa ekuphenduleni kwe-fluorination kanye nokusabela kwe-alkylation. Ngaphezu kwalokho, ingasetshenziswa futhi ukulungisa izibulala-zinambuzane, izinto ze-photoelectric nezinye izinhlanganisela eziphilayo.
Indlela Yokulungiselela:
Kunezindlela eziningi zokuhlanganisa ze-phosphor, futhi indlela evamile itholakala ngokusabela kwe-4-bromo-fluorobenzene kanye negesi ye-fluorine phambi kwe-catalyst. Indlela ethize yokulungiselela idinga imisebenzi nemibandela ethile yaselabhorethri.
Ulwazi Lokuphepha:
-ngokuvamile iphephile uma kuqhathaniswa ngaphansi kwezimo ezijwayelekile zokusebenzisa. Kodwa-ke, noma iyiphi into yamakhemikhali kufanele isetshenziswe ngendlela efanele futhi ilandele izinqubo zokusebenza eziphephile.
-Gqoka izinto zokuzivikela ezifanele njengamagilavu okuzivikela, izibuko kanye namamaski okuzivikela lapho usetshenziswa.
-Gwema ukuphefumula umhwamuko wayo noma ukuthinta isikhumba namehlo.
-Ngesikhathi sokugcina nokuphatha, gwema ukuthintana nama-oxidants aqinile nezimo zokushisa eziphezulu.
-Uma kwenzeka ukuthintana ngephutha noma kusetshenziswe kabi, funa usizo lwezempilo ngokushesha.
