Isingeniso

I-Methyl iyinhlanganisela ye-organic enezici ezilandelayo:

 

1. Ukubukeka: Iwuketshezi olungenambala ukuya kokuphuzi ngokukhanyayo.

2. Ifomula yemolekyuli: C8H7BrNO2.

3. Isisindo sengqamuzana: 216.05g/mol.

4. Ukunyibilika: Incibilika kuzincibilikisi zemvelo njenge-ethanol ne-dichloromethane, ayincibiliki emanzini.

5. Iphuzu Elincibilikayo: cishe ku-26-28 ℃.

 

Ukusetshenziswa kwayo Okuyinhloko kuhlanganisa:

 

1. I-Organic Synthesis: I-Methyl ivame ukusetshenziswa njenge-organic synthesis intermediate ukuze kuhlanganiswe izinhlobonhlobo zezinhlanganisela eziphilayo.

2. Ucwaningo lwesibulala-zinambuzane: Luphinde lusetshenziswe ocwaningweni lwesibulala-zinambuzane njengesandulela sokwenziwa kwezibulala-zinambuzane.

 

Indlela:

 

I-Methyl L ingalungiswa ngezinyathelo ezilandelayo:

 

1. Okokuqala, i-2-picolinic acid (i-Pyridine-2-carboxylic acid) isabela nge-methylisium bromide (methyllitium) ukuze ikhiqize i-2-methyl-pyridine (i-Methyl pyridine-2-carboxylate).

2. Bese, i-2-Methyl formate pyridine iphendulwa nge-brominated sulfoxide (Sulfuryl bromide) ukuze kutholwe i-methyll.

 

Ulwazi Lokuphepha:

 

1. Ukugcinwa kwe-Methyl L kufanele kwenziwe endaweni enomoya omuhle, ukugwema ukukhanya kwelanga okuqondile.

2. Uma usetshenziswa, kufanele ugqoke amagilavu ​​okuzivikela kanye nezibuko, gwema ukuthintana ngqo nesikhumba namehlo.

3. In the inqubo manipulation kufanele ugweme inhalation of umhwamuko yayo, isidingo ukusebenza endaweni umoya kahle laboratory izimo.

4. Uma uthintana ngephutha noma uhogele umoya, geza ngokushesha ngamanzi amaningi futhi ufune usizo lwezempilo.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
