| Amakhodi Engozi | R37/38 – Kuyacasula isimiso sokuphefumula kanye nesikhumba. R41 – Ingozi yokulimala okukhulu emehlweni R36/37/38 – Kuyacasula amehlo, isimiso sokuphefumula kanye nesikhumba. R20/22 – Kuyingozi uma kuhogelwa futhi uma kugwinya. R36 – Kuyacasula amehlo R20/21/22 – Kuyingozi uma kuhogelwa, kuthinteka esikhumbeni futhi uma kugwinya. R11 – Kuyasha kakhulu |
| Incazelo Yokuphepha | S26 – Uma kuthinteka emehlweni, geza ngokushesha ngamanzi amaningi bese uthola izeluleko zikadokotela. S39 – Gqoka isivikelo samehlo / sobuso. S36/37/39 – Gqoka izingubo ezivikelayo ezifanele, amagilavu kanye nesivikelo samehlo/sobuso. S36/37 – Gqoka izingubo ezivikelayo ezifanele kanye namagilavu. S16 – Gcina kude nemithombo yokuthungela umlilo. |

Isingeniso
I-4,5-Dicyanoimidazole (4,5-Dicyanoimidazole) iyinhlanganisela yemvelo. Okulandelayo kunikeza ulwazi mayelana nezakhiwo zayo, ukusetshenziswa, ukulungiselela, kanye nokuphepha: Izakhiwo: - Ukubukeka: I-4,5-Dicyanoimidazole iyikristalu engenambala noma i-powder emhlophe eqinile. - Ukuncibilika: Cishe ayincibiliki emanzini kodwa iyancibilika kuma-solvents emvelo njenge-ethanol ne-ether. - Ukuzinza: Izinzile ngokwanele ngaphansi kwezimo ezijwayelekile. Ukusetshenziswa: - I-Catalyst: I-4,5-Dicyanoimidazole ingasetshenziswa njenge-catalyst ebalulekile ekuhlanganiseni izinto zemvelo njenge-oxidation, i-disproportionation, ne-carbonylation. - I-Chemical reagent: Ekuhlanganiseni izinto zemvelo, i-4,5-Dicyanoimidazole ivame ukusetshenziswa njenge-intermediate noma i-reagent ekuhlanganiseni okuhlukahlukene kwezinto zemvelo. Ukulungiselela: - I-4,5-Dicyanoimidazole ingalungiselelwa ngokusabela kwe-urea ne-hydrogen cyanide ngaphansi kwezimo ze-alkaline. - Izindlela ezithile zokulungiselela zingatholakala kuma-manuals okuhlanganisa i-organic chemistry noma emibhalweni yesayensi. Ulwazi Lokuphepha: - I-4,5-Dicyanoimidazole iphephile ngokwanele ngaphansi kwezimo ezijwayelekile. Njengento yekhemikhali, ukuphatha nokugcina kahle kubaluleke kakhulu. - Lapho usebenzisa noma uphatha i-4,5-Dicyanoimidazole, izinqubo ezijwayelekile zokuphepha zaselabhorethri kufanele zilandelwe. - Gwema ukuthintana nesikhumba namehlo, futhi uqinisekise ukuthi kunomoya owanele. - Uma kwenzeka ukuthintana noma ukuhogela ngengozi, geza ngokushesha ngamanzi noma ufune usizo lwezempilo.
