| Amakhodi Engozi | U-R10 – Uyavutha R25 – Kunobuthi uma ugwinywe R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. I-R11 – Ivutha Kakhulu |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) S37 – Gqoka amagilavu afanelekile. S36 – Gqoka izingubo ezifanele zokuzivikela. |

Isingeniso
I-3-(trifluoromethyl)pyridine, eyaziwa nangokuthi i-1-(trifluoromethyl)pyridine, iyinhlanganisela yezinto eziphilayo.
Ikhwalithi:
3-(trifluoromethyl)pyridine uketshezi olungenambala olunephunga elinamandla. Incibilika kuzincibilikisi eziningi eziphilayo njenge-ethanol, i-dimethylformamide, ne-dimethyl sulfoxide.
Sebenzisa:
I-3-(i-trifluoromethyl) i-pyridine isetshenziswa kabanzi njengama-catalysts, ama-solvents nama-reagents ku-organic synthesis. Ingasetshenziswa njenge-reagent ye-boron chloride ekuhlanganiseni ama-alcohol, ama-acids, kanye nokuphuma kwe-ester. Ingasetshenziswa futhi njenge-sodium hydroxide-catalyzed borate esterification reagent yama-aldehydes nama-ketones.
Indlela:
Kunezindlela ezimbalwa zokulungisa i-3-(trifluoromethyl)pyridine. Indlela evamile ukuthola umkhiqizo ngokusabela kwe-pyridine ne-trifluoromethylsulfonyl fluoride. I-pyridine yancibilika ku-ether solvent, kwase kuthi i-trifluoromethylsulfonyl fluoride yengezwa kancane kancane. Ukusabela kuvame ukwenziwa emazingeni okushisa aphansi futhi kudinga umoya owanele ukugwema ukusabalala kwamagesi anobuthi.
Ulwazi Lokuphepha: Luwuketshezi oluvutha kalula olungabangela umlilo lapho luchayeke elangabini elivulekile noma izinga lokushisa eliphezulu. Kuphinde kube yi-solvent ephilayo engase ibe nomthelela ocasulayo esikhumbeni, emehlweni, nasohlelweni lokuphefumula. Amagilavu okuzivikela, izibuko, nemishini yokuphefumula kufanele kugqokwe ngesikhathi sokusebenza, futhi ukuhlinza kufanele kwenziwe endaweni enomoya omuhle.
