Isingeniso
I-6-CHLORO-4-METHYLPYRIDIN-3-CARBOXALDEHYDE (2-CHLORO-5-FORMYL-4-PICOLINE) INGQUNGQUTHELA YEMPILO. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-6-Chloro-4-methylpyridine-3-carboxaldehyde iwuketshezi olungenambala ukuya kokuphuzi okuphaphathekile.
- Ukunyibilika: Ingancibilika kuzincibilikisi eziningi eziphilayo, njenge-ethanol, i-ether, ne-chloroform.
- Ukuzinza: Le nhlanganisela izinzile ekamelweni lokushisa, kodwa ingabola ngaphansi kokushisa, ilangabi, noma izimo ezine-asidi eqinile.
Sebenzisa:
- I-6-chloro-4-methylpyridine-3-carboxaldehyde iyingxenye ebalulekile ekuhlanganiseni kwezinto eziphilayo futhi ivame ukusetshenziselwa ukulungiswa kwamanye ama-organic compounds.
Indlela:
I-6-Chloro-4-methylpyridine-3-carboxaldehyde ivamise ukulungiselelwa ukusabela kokuhlanganiswa okufana nezinyathelo ezilandelayo:
1. I-4-methylpyridine iphathwa nge-alkali ukuze ithole ama-ion angalungile ahambisanayo.
2. Ama-ion angemuhle asabela nge-cuprous chloride ukuze kwakheke i-alkyl copper intermediate.
3. I-Alkyl copper intermediate isabela nge-formaldehyde ukuze yenze i-6-chloro-4-methylpyridine-3-carboxaldehyde.
Ulwazi Lokuphepha:
- I-6-Chloro-4-methylpyridine-3-carboxaldehyde ingase ibe yingozi emzimbeni womuntu, futhi izinyathelo zokuphepha ezidingekayo kufanele zithathwe lapho uyisebenzisa, njengokugqoka izinto zokuzivikela ezifanele (njengamagilavu, izibuko, nezingubo zokuzivikela).
- Kufanele igcinwe endaweni epholile, eyomile futhi enomoya omuhle, kude nomlilo kanye nama-oxidants.
- Gwema ukuhogela, ukuthintana kwesikhumba kanye nokumunca ngesikhathi sokuphatha nokusebenzisa.
- Ngokushesha ngemva kokuxhumana, geza indawo yesikhumba engcolile ngamanzi amaningi futhi ufune usizo lwezokwelapha.
