| Izimpawu Eziyingozi | C – Iyabola |
| Amakhodi Engozi | R34 – Ibangela ukusha R36/37 – Ukucasula amehlo kanye nesistimu yokuphefumula. |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S27 – Khumula ngokushesha zonke izingubo ezingcolile. I-S28 – Ngemva kokuxhumana nesikhumba, geza ngokushesha ngensipho eningi. 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.) |

Isingeniso
I-Diethyl chloromalonate (eyaziwa nangokuthi i-DPC). Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-diethyl chloromalonate:
1. Imvelo:
- Ukubukeka: I-Diethyl chloromalonate iwuketshezi olungenambala.
- Ukunyibilika: Kuncibilika kuzincibilikisi eziningi eziphilayo, njengotshwala, ama-ether, nama-hydrocarbon anephunga elimnandi, kodwa ancibilika kancane emanzini.
- Ukuzinza: Ayizinzile ekukhanyeni nasekushiseni, kodwa ingakhiqiza igesi enobuthi ye-hydrogen chloride emazingeni okushisa aphezulu noma amalangabi avulekile.
2. Ukusetshenziswa:
- Njengesincibilikisi: I-Diethyl chloromalonate ingasetshenziswa njengesixazululi, ikakhulukazi ku-organic synthesis ukuze incibilike futhi isabele izinhlanganisela eziphilayo.
- I-Chemical synthesis: I-reagent evame ukusetshenziselwa ukuhlanganiswa kwama-esters, ama-amide, nezinye izinhlanganisela eziphilayo.
3. Indlela:
- I-Diethyl chloromalonate ingatholwa ngokusabela kwe-diethyl malonate nge-hydrogen chloride. Izimo zokusabela ngokuvamile zisezingeni lokushisa lasekamelweni, igesi ye-hydrogen chloride yethulwa ku-diethyl malonate, futhi i-catalyst iyengezwa ukukhuthaza ukusabela.
- Izibalo zokusabela: CH3CH2COOCH2CH3 + HCl → ClCH2COOCH2CH3 + H2O
4. Ulwazi Lokuphepha:
- I-Diethyl chloromalonate inephunga elimnandi futhi ingase ibangele ukucasuka esikhumbeni, emehlweni, kanye nomgudu wokuphefumula.
- Luwuketshezi oluvutha umlilo oludinga ukugcinwa endaweni epholile, enomoya omuhle futhi kude nemithombo yomlilo namalangabi avulekile.
- Izinto zokuzivikela ezifanele ezifana namagilavu, izibuko, nezingubo zokuzivikela kufanele zigqokwe ngesikhathi sokuphatha.
