Mawu Oyamba
M-chlorobenzaldehyde (yomwe imadziwikanso kuti p-chlorobenzaldehyde) ndi organic compound. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:
Ubwino:
- Maonekedwe: M-chlorobenzaldehyde ndi madzi achikasu owala komanso onunkhira.
- Kusungunuka: Ikhoza kusungunuka muzitsulo zambiri za organic, monga ethanol, dimethylformamide, ndi zina zotero, koma kusungunuka kwake kumakhala kochepa kuposa madzi.
Gwiritsani ntchito:
- Aldehyde kuchiritsa wothandizira: Itha kugwiritsidwa ntchito ngati mankhwala a aldehyde mu utomoni, zokutira ndi zida zina kuti zigwire ntchito yochiritsa yolumikizirana.
Njira:
Njira zokonzekera za m-chlorobenzaldehyde makamaka ndi izi:
- Kuphatikizika kwa klorini: Mchitidwe wa klorini pakati pa p-nitrobenzene ndi cuprous chloride umatulutsa m-chlorobenzaldehyde.
- Chlorination: p-nitrobenzene amathiridwa chlorine pochepetsa kupanga p-chloroaniline, kenako kudzera mu redox reaction kupanga m-chlorobenzaldehyde.
- Hydrogenation: p-nitrobenzene imapangidwa ndi hydrogenated kupanga m-chloroaniline, kenako redox kupanga m-chlorobenzaldehyde.
Zambiri Zachitetezo:
- Kukoka mpweya kapena kumeza m-chlorobenzaldehyde kungayambitse poyizoni, ndipo kupuma kwa nthunzi kapena splashes mkamwa kuyenera kupewedwa. Funsani kuchipatala mwamsanga ngati mukudya kapena kupuma.
- Pewani kukhudzana ndi ma okosijeni, ma asidi amphamvu ndi zinthu zina zovulaza, ndipo pewani kuyatsa kapena kutentha kwambiri.
Kuti mugwiritse ntchito mwachindunji, chonde tsatirani malamulo oyenera komanso malangizo ogwiritsira ntchito chitetezo.
