Isingeniso

I-2-Formylthiazole iyinhlanganisela yezinto eziphilayo.

Ukuncibilika: Ingancibilika emanzini futhi ingancibilika kuzincibilikisi eziningi eziphilayo, njengotshwala, ama-ether nama-ketone.

Ukuzinza: Ayizinzile ekushiseni nomoya-mpilo futhi ibola kalula.

I-Reactivity: I-2-Formylthiazole ingenza umsebenzi wayo wokusabela kwamakhemikhali ngokusabela kwe-nucleophilic substitution, kanye ne-acylation, amidation, njll.

 

Izicelo ze-2-Formylthiazole:

 

Isibulala-zinambuzane: I-2-Formylthiazole isibulala-zinambuzane esingasetshenziswa ukulawula izinambuzane ezitshalweni nasezihlahleni zezithelo.

 

Ukulungiswa kwe-2-formylthiazole kuvame ukwenziwa ngalezi zindlela ezilandelayo:

 

I-Nucleoacylation: I-Chloroacetyl chloride isabela ne-thioethanol ngaphansi kwezimo ze-alkali ukukhiqiza i-2-formylthiazole.

Ukusabela kwe-condensation: I-2-formylthiazole ingatholwa ngokuphendula i-acetylacetamide nge-sodium thiocyanate ngaphansi kwezimo ze-alkali.

 

1.2-I-Formylthiazole iyacika futhi ingase ibangele ukungaphatheki kahle kwesikhumba namehlo lapho uthintana. Gqoka izinto zokuzivikela ezifanele ezifana namagilavu, izibuko, njll. lapho usebenza.

Gwema ukuhogela noma ukungenisa i-2-formylthiazole futhi ufune usizo lwezokwelapha ngokushesha uma ugwinywe ngephutha noma uhogelwe ngobuningi.

I-2-Formylthiazole kufanele igcinwe endaweni epholile, engenawo umoya, kude nomlilo kanye nama-oxidants.

Lapho kulahlwa udoti, izidingo ezifanele zokulawula imvelo kufanele zibhekwe.

 

Izakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2-formylthiazole kuchazwe ngenhla.

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