Mawu Oyamba

2-Formylthiazole ndi organic pawiri.

Kusungunuka: Ikhoza kusungunuka m'madzi ndipo imatha kusungunuka muzinthu zambiri zosungunulira, monga ma alcohols, ethers ndi ketones.

Kukhazikika: Imakhala yosakhazikika kutentha ndi mpweya ndipo imawola mosavuta.

Reactivity: 2-Formylthiazole imatha kuchita ntchito yake yamankhwala kudzera mu nucleophilic substitution reaction, ndipo acylation, amidation, ndi zina zambiri.

 

Kugwiritsa ntchito 2-Formylthiazole:

 

Mankhwala ophera tizilombo: 2-Formylthiazole ndi mankhwala ophera tizirombo omwe amatha kugwiritsidwa ntchito pothana ndi tizirombo pa mbewu ndi mitengo yazipatso.

 

Kukonzekera kwa 2-formylthiazole kumachitika motere:

 

Nucleoacylation: Chloroacetyl chloride imayendetsedwa ndi thioethanol pansi pamikhalidwe yamchere kuti ipange 2-formylthiazole.

Condensation anachita: 2-formylthiazole akhoza kuwapeza pochita acetylacetamide ndi sodium thiocyanate pansi zamchere mikhalidwe.

 

1.2-Formylthiazole imakwiyitsa ndipo imatha kuyambitsa kusapeza bwino pakhungu ndi maso mukakumana. Valani zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi zina zambiri.

Pewani kulowetsa kapena kumeza 2-formylthiazole ndipo funsani chithandizo chamankhwala mwamsanga ngati mwamezedwa mwangozi kapena kutsekemera kwambiri.

2-Formylthiazole iyenera kusungidwa pamalo ozizira, opanda mpweya wabwino, kutali ndi moto ndi oxidants.

Potaya zinyalala, zofunikira zoyendetsera chilengedwe ziyenera kuwonedwa.

 

The katundu, ntchito, kukonzekera njira ndi chitetezo zambiri za 2-formylthiazole tafotokozazi.
