Sebenzisa Isetshenziswa njengezinto eziyisisekelo zamakhemikhali emvelo, ezisetshenziswa kabanzi kwezokwelapha, ukudla, amakhemikhali nsuku zonke, izindwangu, iphepha, upende nezinye izimboni.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amakhodi Engozi R36 – Ukucasuka emehlweni
R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile.
I-R11 – Ivutha Kakhulu
Incazelo Yokuphepha I-S24/25 - Gwema ukuthintana nesikhumba namehlo.
S39 – Gqoka ukuvikela iso / ubuso.
S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.

Isingeniso

Incibilika emanzini nasetshwaleni, ayincibiliki ku-ether, benzene, chloroform ne-carbon disulfide, futhi imunca kalula amanzi emoyeni. Inokunambitheka okumnandi okufudumele. Ingakwazi ukumunca umswakama ovela emoyeni, kanye ne-hydrogen sulfide, i-hydrogen cyanide ne-sulphur dioxide. Ingathathi hlangothi ku-litmus. Isikhathi eside ekushiseni okuphansi okungu-0 ℃, izixube ezinamandla ezifana ne-chromium trioxide, i-potassium chlorate, ne-potassium permanganate zingabangela ukusha nokuqhuma. Ingaxubana ngokuzenzakalelayo namanzi ne-ethanol, ingxenye engu-1 yalo mkhiqizo ingancibilika ezingxenyeni ezingu-11 ze-ethyl acetate, izingxenye ezingaba ngu-500 ze-ether, ezingancibiliki ku-chloroform, i-carbon tetrachloride, i-petroleum ether namafutha. Isilinganiso esibulalayo esimaphakathi (igundane, ngomlomo)>20ml/kg. Kuyacasula.
