i-ethyl 6-chloropyridine-2-carboxylate (CAS# 21190-89-6)

Isingeniso

I-ethyl iyinhlanganisela ye-organic ene-chemical formula C8H6ClNO2. Iwuketshezi olungenambala olunephunga elimnandi. Okulandelayo ezinye izici mayelana ne-compound:

Imvelo:

-Ukuminyana: cishe. 1.28 g/mL

-Indawo yokubilisa: Cishe ku-250 ° C

-Indawo yokuncibilika: mayelana ne-29 ° C

-Ukunyibilika: Kuncibilika kwezinye izinyibilikisi zemvelo, njenge-ethanol, i-dichloromethane ne-ether

Sebenzisa:

- I-ethyl L isetshenziswa kabanzi njengendawo ephakathi kokuhlangana kwe-organic futhi isetshenziswa ekuhlanganiseni kwezidakamizwa nezibulala-zinambuzane.

-Ingasetshenziswa futhi njenge-solvent kanye ne-catalyst ekuphenduleni kwe-organic synthesis.

Indlela: Indlela yokulungiselela ye

I-ethyl L ikakhulukazi ihlanganisa lezi zinyathelo ezilandelayo:

1. Yenza i-6-chloropyridine ne-sodium cyanide ukukhiqiza i-6-chloropyridine -2-carbonitrile.

2. Yenza i-6-chloropyridine-2-carbonitrile ngotshwala ikhiqize i-6-chloropyridine-2-carbonitrile alcohol.

3. Ekugcineni, i-6-chloropyridine-2-nitrile alcohol isabela nge-asidi ukuze kukhiqizwe i-ethyl L.

Ulwazi Lokuphepha:

I-ethyl L iyacasula futhi ingase ibangele ukucasuka esikhumbeni, amehlo kanye nomgudu wokuphefumula. Ngakho-ke, izinto zokuzivikela ezifanele njengamagilavu, izibuko zokuphepha kanye nezinto zokuvikela ukuphefumula kufanele zigqokwe lapho kusetshenziswa into.

Ngaphezu kwalokho, i-compound nayo iyavutha futhi kufanele igcinwe kude namalangabi avulekile namazinga okushisa aphezulu. Izindlela eziphephile kufanele zilandelwe lapho ugcina futhi uphatha into.
