| Izimpawu Eziyingozi | I-Xn - Iyingozi |
| Amakhodi Engozi | I-R22 – Iyingozi uma igwinywe R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| 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. |
| Ikhodi ye-HS | 29335990 |
Isingeniso
Kuyinhlanganisela yemvelo enefomula yamakhemikhali i-C5H5ClN2. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
Iwuketshezi olungenambala ukuya kokuphuzi olunephunga elikhethekile. Inephuzu eliphansi lokubilisa kanye nendawo yokuncibilika ekamelweni lokushisa. Incibilika kuma-organic solvents njenge-diethyl ether, i-acetone ne-dichloromethane.
Sebenzisa:
Kuyinto ebalulekile ye-organic intermediate, engasetshenziswa kabanzi ekuhlanganiseni kwezidakamizwa nezibulala-zinambuzane. Isetshenziswa njengengxenye ephakathi ekuhlanganiseni kwezinhlobonhlobo zezidakamizwa ezifana nezidakamizwa ezilwa namagciwane kanye nezidakamizwa ze-antitumor. Ngaphezu kwalokho, ingasetshenziswa futhi ukulungisa amanye ama-organic compounds, afana namadayi kanye nama-coordination compounds.
Indlela:
Indlela yokulungisa i-calcium ingatholakala ngokusabela i-2-methyl pyrimidine nge-thionyl chloride. Izimo ezithile zokusabela zingalungiswa ngokuvumelana nezidingo zokuhlola, kodwa izimo ezivamile zenziwa ngaphansi komkhathi ongasebenzi, izinga lokushisa legumbi noma ukushisa.
Ulwazi Lokuphepha:
Inobuthi obuphansi ngaphansi kwezimo zokusetshenziswa Okujwayelekile, kodwa izinyathelo ezifanele zokuvikela zisadingeka. Ngesikhathi sokusebenza, ukuthintana nesikhumba, amehlo kanye nokuhogela umhwamuko kufanele kugwenywe, futhi izibuko zokuzivikela namagilavu kufanele kugqokwe uma kunesidingo. Uma uhlangana nalesi sithako, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha. Ngesikhathi esifanayo, gwema ukuyixuba nama-oxidants aqinile nama-asidi aqinile ukuze ugweme umlilo noma ukuqhuma. Isitoreji kufanele sibekwe endaweni eyomile, epholile, enomoya omuhle, kude nomlilo nezinto ezivuthayo.
