Taw qhia
2-Formylthiazole yog ib qho organic compound.
Solubility: Nws tuaj yeem yaj hauv dej thiab tuaj yeem yaj hauv ntau cov kuab tshuaj organic, xws li cawv, ethers thiab ketones.
Stability: Nws tsis ruaj khov rau cua sov thiab oxygen thiab decomposes yooj yim.
Reactivity: 2-Formylthiazole tuaj yeem ua tiav nws cov tshuaj tiv thaiv kev ua haujlwm los ntawm nucleophilic hloov cov tshuaj tiv thaiv, thiab acylation, amidation, thiab lwm yam tuaj yeem tshwm sim.
Kev siv ntawm 2-Formylthiazole:
Tshuaj tua kab: 2-Formylthiazole yog tshuaj tua kab uas siv tau los tswj cov kab tsuag ntawm cov qoob loo thiab cov ntoo txiv ntoo.
Kev npaj ntawm 2-formylthiazole feem ntau yog ua los ntawm cov hauv qab no:
Nucleoacylation: Chloroacetyl chloride yog reacted nrog thioethanol nyob rau hauv alkaline tej yam kev mob los tsim 2-formylthiazole.
Cov tshuaj tiv thaiv condensation: 2-formylthiazole tuaj yeem tau txais los ntawm kev ua haujlwm ntawm acetylacetamide nrog sodium thiocyanate nyob rau hauv cov xwm txheej alkaline.
1.2-Formylthiazole yog khaus thiab ua rau tawv nqaij thiab qhov muag tsis xis nyob thaum sib cuag. Hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab lwm yam thaum ua haujlwm.
Tsis txhob nqus los yog nqos 2-formylthiazole thiab nrhiav kev kho mob tam sim yog tias nqos los yog nqus tau ntau heev.
2-Formylthiazole yuav tsum muab cia rau hauv qhov chaw txias, qhov cua zoo, kom deb ntawm hluav taws thiab oxidants.
Thaum pov tseg cov khoom pov tseg, yuav tsum tau ua raws li kev cai tswj hwm ib puag ncig tsim nyog.
Cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 2-formylthiazole tau piav qhia saum toj no.
