Intangiriro

Dibromodifluoromethane (CBr2F2), izwi kandi nka halothane (halothane, trifluoromethyl bromide), ni ifumbire mvaruganda. Ibikurikira nintangiriro kumiterere, ikoreshwa, uburyo bwo gutegura namakuru yumutekano ya dibromodifluoromethane:

Ubwiza:

- Kugaragara: Amazi adafite ibara

- Gukemura: gushonga muri Ethanol, ether na chloride, gushonga gake mumazi

- Uburozi: bugira ingaruka zo gutera anesthetic kandi burashobora gutuma habaho kwiheba kwa sisitemu yo hagati

Koresha:

- Anesthetics: Dibromodifluoromethane, yigeze gukoreshwa cyane muri anesthesia yimitsi na rusange, ubu yasimbujwe anesthetike yateye imbere kandi itekanye.

Uburyo:

Gutegura dibromodimomethane birashobora gukorwa nintambwe zikurikira:

Bromine ikorwa na fluor mubushyuhe bwinshi kugirango itange fluorobromide.

Fluorobromide ikoreshwa na metani munsi ya ultraviolet imirasire kugirango itange dibromodifluoromethane.

Amakuru yumutekano:

- Dibromodifluoromethane ifite anesthetic kandi igomba gukoreshwa ubwitonzi, cyane cyane idafite ubuyobozi bwumwuga.

- Kumara igihe kinini kuri dibromodifluoromethane bishobora kugira ingaruka mbi kumwijima.

- Irashobora gutera uburakari iyo yinjiye mumaso, uruhu, cyangwa sisitemu yubuhumekero.

- Iyo ukoresheje dibromodifluoromethane, flame cyangwa ibihe by'ubushyuhe bwo hejuru bigomba kwirindwa kuko byaka.

- Mugihe ukoresheje dibromodifluoromethane, kurikiza imikorere ya laboratoire hamwe nuburyo bwo kurinda umuntu.
