Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amakhodi Engozi R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
R43 - Ingabangela ukuzwela ngokuthinta isikhumba
R50/53 – Kunobuthi kakhulu ezintweni eziphila emanzini, kungabangela imiphumela emibi yesikhathi eside endaweni yasemanzini.
Incazelo Yokuphepha S22 - Ungaphefumuli uthuli.
I-S24/25 - Gwema ukuthintana nesikhumba namehlo.
I-S36/37 – Gqoka izingubo zokuzivikela ezifanele namagilavu.
S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
I-S61 - Gwema ukudedelwa endaweni. Bheka imiyalelo ekhethekile / amaphepha edatha okuphepha.
S60 – Le nto kanye nesiqukathi sayo kumele kulahlwe njengemfucuza eyingozi.

Isingeniso

I-sublimation ku-vacuum ephezulu. I-1g ye-glacial acetic acid ebilayo incibilike ku-13g. I-soluble ku-ethanol ibomvu, inyibilika ku-ether insundu ne-fluorescent ephuzi, i-alkali futhi i-ammonia insomi. Endabeni ye-carbon dioxide, imvula emnyama ikhiqizwa. Kuyacasula.
