Taw qhia
M-chlorobenzaldehyde (tseem hu ua p-chlorobenzaldehyde) 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:
Zoo:
- Cov tsos mob: M-chlorobenzaldehyde yog xim tsis muaj xim rau lub teeb daj nrog cov ntxhiab tsw.
- Solubility: Nws tuaj yeem yaj hauv feem ntau cov kuab tshuaj organic, xws li ethanol, dimethylformamide, thiab lwm yam, tab sis nws cov solubility qis dua li dej.
Siv:
- Aldehyde curing agent: Nws tuaj yeem siv los ua tus neeg sawv cev aldehyde curing hauv resins, coatings thiab lwm yam ntaub ntawv los ua lub luag haujlwm ntawm kev sib txuas sib txuas.
Txoj kev:
Kev npaj ntawm m-chlorobenzaldehyde feem ntau yog raws li hauv qab no:
- Chlorination: Cov tshuaj chlorination ntawm p-nitrobenzene thiab cuprous chloride tsim m-chlorobenzaldehyde.
- Chlorination: p-nitrobenzene yog chlorinated los ntawm kev txo qis rau p-chloroaniline, thiab tom qab ntawd los ntawm cov tshuaj tiv thaiv redox los ua m-chlorobenzaldehyde.
- Hydrogenation: p-nitrobenzene yog hydrogenated los tsim m-chloroaniline, thiab tom qab ntawd redox los ua m-chlorobenzaldehyde.
Cov ntaub ntawv kev nyab xeeb:
- Kev nqus tau los yog noj ntawm m-chlorobenzaldehyde tuaj yeem ua rau muaj tshuaj lom, thiab kev nqus pa los yog txaws rau hauv lub qhov ncauj yuav tsum zam. Nrhiav kev kho mob sai yog tias koj noj lossis nqus pa.
- Tsis txhob sib cuag nrog oxidants, muaj zog acids thiab lwm yam teeb meem, thiab tsis txhob ignition lossis kub kub.
Rau kev siv tshwj xeeb, thov ua raws li cov kev cai cuam tshuam thiab cov lus qhia kev nyab xeeb.
