-Indawo yokunyibilika: malunga ne-29 ° C

-Ukunyibilika: Ukunyibilika kwezinye izinyibilikisi eziphilayo, ezifana ne-ethanol, i-dichloromethane kunye ne-ether

Sebenzisa:

- i-ethyl L isetyenziswa ngokubanzi njengendawo ephakathi kwi-organic synthesis kwaye isetyenziselwa ukuhlanganiswa kweziyobisi kunye nezibulala-zinambuzane.

-Inokuthi isetyenziswe njenge-solvent kunye ne-catalyst kwi-organic synthesis reactions.

Indlela: Indlela yokulungiselela ye

I-ethyl L iquka la manyathelo alandelayo:

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

2. Yenza i-6-chloropyridine-2-carbonitrile kunye notywala ukuvelisa i-6-chloropyridine-2-carbonitrile alcohol.

3. Ekugqibeleni, i-6-chloropyridine-2-nitrile alcohol iphendulwa ngeasidi ukuvelisa i-ethyl L.

Ulwazi ngoKhuseleko:

I-ethyl L iyacaphukisa kwaye inokubangela ukucaphuka kwesikhumba, amehlo kunye nomgudu wokuphefumla. Ke ngoko, izixhobo ezifanelekileyo zokukhusela ezinjengeeglavu, iiglasi zokhuseleko kunye nezixhobo zokhuselo lokuphefumla kufuneka zinxitywe xa kusetyenziswa loo nto.

Ukongeza, i-compound nayo inokutsha kwaye kufuneka igcinwe kude namadangatye avulekileyo kunye namaqondo okushisa aphezulu. Iindlela ezikhuselekileyo kufuneka zilandelwe xa kugcinwa naxa kusingathwa loo nto.
