Intshayelelo

I-Methyl yikhompawundi ephilayo eneempawu ezilandelayo:

 

1. Imbonakalo: Lulwelo olungenambala ukuya kumthubi okhanyayo.

2. Ifomula yemolekyuli: C8H7BrNO2.

3. Ubunzima bemolekyuli: 216.05g/mol.

4. I-Solubility: I-soluble kwi-solvents ye-organic efana ne-ethanol kunye ne-dichloromethane, i-soluble emanzini.

5. Indawo enyibilikayo: malunga ne-26-28 ℃.

 

Usetyenziso lwayo oluphambili lubandakanya:

 

1. I-Organic Synthesis: I-Methyl isoloko isetyenziswa njenge-organic synthesis intermediate ukwenzela ukuhlanganiswa kweentlobo ezahlukeneyo zezinto eziphilayo.

2. Uphando lwezitshabalalisi: Ikwasetyenziswa kuphando lwesitshabalalisi njengesandulela sokwenziwa kwezibulali zinambuzane.

 

Indlela:

 

IMethyl L inokulungiswa ngala manyathelo alandelayo:

 

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

2. Emva koko, i-2-Methyl formate pyridine iphendulwa nge-brominated sulfoxide (Sulfuryl bromide) ukufumana i-methyll.

 

Ulwazi ngoKhuseleko:

 

1. Ukugcinwa kweMethyl L kufuneka kuqhutywe kwindawo enomoya, ukuphepha ukukhanya kwelanga.

2. Xa usebenzisa, kufuneka unxibe iiglavu zokukhusela kunye neeglasi, ugweme ukudibanisa ngokuthe ngqo kwesikhumba kunye namehlo.

3. Kwinkqubo yokukhwabanisa kufuneka igweme ukuphefumla umphunga wayo, kufuneka isebenze kwiimeko zebhubhoratri ezinomoya.

4. Kwimeko yokudibanisa ngengozi okanye ukuphefumla, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune unyango.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
