Isingeniso

I-Methyl trifluoropalmitate (i-trifluoroacetic acid ester) iyinhlanganisela yezinto eziphilayo. Ifomula yayo yamangqamuzana ithi CF3COOCH3 futhi isisindo sayo samangqamuzana ngu-114.04g/mol. Nalu olunye ulwazi mayelana ne-trifluoropalmitate methyl ester:

 

Imvelo:

1. ukubukeka: i-trifluoro palmitate methyl ester iwuketshezi olungenambala.

2. indawo encibilikayo:-76 ℃

3. Iphuzu elibilayo: 32-35 ℃

4. ukuminyana: 1.407g/cm³

5. Ukuzinza: I-Trifluoropalmitate methyl ester inokusimama okuhle kwamakhemikhali, kodwa ingasabela ngobudlova ngama-oxidants aqinile.

 

Sebenzisa:

1. Ukwenziwa kwe-Organic: i-trifluoro palmitate methyl ester ivamise ukusetshenziswa njenge-catalyst, reagent kanye ne-solvent, futhi idlala indima ebalulekile enqubweni ye-organic synthesis. Ingasetshenziswa ekuphenduleni kwe-esterification, ukusabela kwe-condensation kanye ne-acid catalyzed reaction.

2. Ukuhlaziywa kwe-chromatographic: i-trifluoropalmitate methyl ester ingasetshenziswa futhi njengejwayelekile noma i-solvent ekuhlaziyeni kwe-chromatographic yegesi.

 

Indlela Yokulungiselela:

I-Trifluoropalmitate methyl ester ingalungiswa ngezindlela ezihlukahlukene. Indlela evame kakhulu ukusabela kwe-trifluoroacetic acid nge-methanol.

 

Ulwazi Lokuphepha:

1. i-trifluoroacetic acid i-methyl ester iyacasula, kufanele igweme ukuthintana nesikhumba, amehlo kanye nomgudu wokuphefumula. Gqoka izinto zokuzivikela ezifanele ezifana namagilavu ​​okuvikela amakhemikhali, izibuko kanye nokuvikela ukuphefumula.

2. Uma udliwe ngephutha noma uhogelwe umoya, funa usizo lwezempilo ngokushesha.

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