2 4-Dichloro pyridine (CAS# 26452-80-2)
| Amakhodi Engozi | R25 – Kunobuthi uma ugwinywe R38 – Ukucasuka esikhunjeni R41 – Ingozi yokulimala okubi emehlweni R43 - Ingabangela ukuzwela ngokuthinta isikhumba R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. U-R20/22 – Kuyingozi ngokuhogela umoya futhi uma ugwinyiwe. |
| 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. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) S36 – Gqoka izingubo ezifanele zokuzivikela. |

Isingeniso
I-2,4-Dichloropyridine iyinhlanganisela yemvelo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2,4-dichloropyridine:
Ikhwalithi:
- 2,4-Dichloropyridine ayinambala kumakristalu aphuzi noma uketshezi.
- Inephunga elimnandi elinamandla.
- 2,4-Dichloropyridine ine-solubility ephansi, ayincibiliki emanzini, kanye ne-solubility enhle kuma-organic solvents.
Sebenzisa:
- I-2,4-Dichloropyridine ingasetshenziswa njenge-reagent ebalulekile kanye ne-catalyst ku-organic synthesis.
- I-2,4-Dichloropyridine ibuye isetshenziswe ngokujwayelekile njenge-ejenti yokwelapha ebusweni bensimbi ukuze kukhishwe amafilimu e-oxide noma ukwehlisa amafutha.
Indlela:
- Indlela yokulungiselela ye-2,4-dichloropyridine ivame ukutholwa ngokusabela kwe-2,4-dichloropyran ne-nitrous acid.
- Ukushisa okufanelekile nesikhathi sokuphendula kuyadingeka ngesikhathi sokuphendula, kanye nokulawula ngaphansi kwezimo ze-acidic.
Ulwazi Lokuphepha:
- I-2,4-Dichloropyridine iyinhlanganisela yezinto eziphilayo, futhi kufanele kuthathwe ukunakekelwa ekusebenzeni okuphephile ngesikhathi sokusetshenziswa.
- Ukuchayeka ku-2,4-dichloropyridine kungase kubangele ukucasuka esikhumbeni, emehlweni, nasohlelweni lokuphefumula.
- Gqoka izinto zokuzivikela ezifanele ezifana namagilavu, izibuko, nama-respirators uma usebenzisa.
Gwema ukuthinta i-2,4-dichloropyridine esikhumbeni esisobala futhi ugcine indawo yokusebenza enomoya omuhle.
- Lapho ulahla udoti we-2,4-dichloropyridine, imithetho yendawo yokulawulwa kwemfucuza kufanele ibhekwe.
