Taw qhia
2-Chloro-4-fluorobenzaldehyde yog cov organic compound. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom, thiab cov ntaub ntawv kev nyab xeeb:
Khoom: Nws yog xim tsis muaj xim rau daj ntseg daj nrog cov ntxhiab tsw. Nws yog insoluble nyob rau hauv dej ntawm chav tsev kub, tab sis soluble nyob rau hauv organic solvents xws li cawv los yog ethers.
Siv:
2-Chloro-4-fluorobenzaldehyde feem ntau yog siv los ua ib qho tseem ceeb nruab nrab ntawm cov organic synthesis. Nws tuaj yeem siv los tsim cov tshuaj lom neeg lom neeg, suav nrog oxachlors, imidazodones, aminoketones, thiab aminoketones, thiab lwm yam. Nws tseem tuaj yeem siv los ua cov khoom siv raw rau tshuaj tua kab thiab tshuaj tua kab.
Txoj kev:
2-Chloro-4-fluorobenzaldehyde tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm 2-chloro-4-fluorobenzoic acid nrog sulfuric acid, thionyl chloride lossis phosphorus chloride. Cov tshuaj tiv thaiv no feem ntau nqa tawm hauv qhov chaw tsis muaj zog thiab xav tau qhov kub thiab txias thiab lub sijhawm tshuaj tiv thaiv.
Cov ntaub ntawv kev nyab xeeb:
2-Chloro-4-fluorobenzaldehyde yog qhov txaus ntshai, thiab nws yuav tsum tau ua tib zoo saib xyuas kev nyab xeeb thaum siv thiab khaws cia. Nws tuaj yeem ua rau khaus thiab ua rau lub qhov muag, tawv nqaij, thiab ua pa, thiab cov khoom siv tiv thaiv zoo xws li hnab looj tes, tsom iav, thiab lub tshuab ua pa yuav tsum hnav thaum ua haujlwm. Tsis txhob kov cov tawv nqaij thiab nqus tau nws cov vapors. Thaum siv, qhov chaw ua haujlwm tau zoo yuav tsum tau khaws cia, thiab khaws cia kom deb ntawm cov nplaim taws thiab qhov kub thiab txias. Nyob rau hauv rooj plaub ntawm kev sib cuag nrog nws, nws yuav tsum tam sim ntawd yaug nrog dej kom ntau thiab nrhiav kev kho mob.
