Intshayelelo

I-2-Formylthiazole yi-organic compound.

Ukunyibilika: Inokunyibilika emanzini kwaye inokunyibilika kwizinyibilikisi ezininzi zezinto eziphilayo, ezinje ngotywala, ii-ethers kunye neeketones.

Ukuzinza: Ayizinzile kubushushu kunye neoksijini kwaye ibola lula.

I-Reactivity: I-2-Formylthiazole inokuqhuba umsebenzi wayo we-chemical reaction ngokusebenzisa i-nucleophilic substitution reaction, kunye ne-acylation, i-amidation, njl.

 

Ukusetyenziswa kwe-2-Formylthiazole:

 

Isibulali zinambuzane: I-2-Formylthiazole sisibulali zinambuzane esinokusetyenziswa ukulawula izitshabalalisi kwizityalo nakwimithi yeziqhamo.

 

Ukulungiswa kwe-2-formylthiazole ngokuqhelekileyo kwenziwa ngezi ndlela zilandelayo:

 

I-Nucleoacylation: I-Chloroacetyl chloride iphendulwa kunye ne-thioethanol phantsi kweemeko ze-alkaline ukuvelisa i-2-formylthiazole.

I-condensation reaction: I-2-formylthiazole inokufumaneka ngokuphendula i-acetylacetamide kunye ne-sodium thiocyanate phantsi kweemeko ze-alkaline.

 

1.2-I-Formylthiazole iyacaphuka kwaye inokubangela ukungahambi kakuhle kwesikhumba kunye neliso xa udibana. Nxiba izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu, iiglasi, njl.njl. xa usebenza.

Kuphephe ukuphefumla okanye ukufunxa i-2-formylthiazole kwaye ufune unyango olukhawulezileyo ukuba uginywe ngempazamo okanye uphefumle kakhulu.

I-2-Formylthiazole kufuneka igcinwe kwindawo epholileyo, indawo engenamoya, kude nomlilo kunye ne-oxidants.

Xa ulahla inkunkuma, iimfuno ezifanelekileyo zolawulo lokusingqongileyo kufuneka ziqwalaselwe.

 

Iipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-2-formylthiazole luchazwe ngasentla.
