2 5-DICHLORO-4-METHYLPYRIDINE(CAS# 886365-00-0)

Isingeniso

I-2,5-dichloro-4-methylpyriridine iyinhlanganisela ye-organic ene-chemical formula C6H5Cl2N. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:

1. imvelo:

-Ukubukeka: uketshezi olungenambala noma okuqinile okucwebezelayo;

-Ukunyibilika: Kuncibilika kuzincibilikisi zemvelo njenge-ether, utshwala nama-hydrocarbons;

-Indawo yokuncibilika:-26°C;

-Iphuzu elibilayo: 134-136 ° C;

-Ukuminyana: 1.36g/cm³.

2. sebenzisa:

-2,5-dichloro-4-methylpyriridine iyingxenye ebalulekile ekuhlanganiseni kwe-organic synthesis futhi inezinhlobonhlobo zezicelo emkhakheni wezokwelapha kanye namakhemikhali;

-Ingasetshenziselwa ukulungisa izibulala-zinambuzane, ama-fungicides nezinye izinhlanganisela eziphilayo;

-ingasetshenziswa futhi njenge-catalyst, i-surfactant kanye ne-dyes intermediates.

3. indlela yokulungiselela:

-Indlela yokulungiselela ye-2,5-dichloro-4-methylpyriridine ngokuvamile itholakala ngokusabela kwe-chlorination ku-pyridine.

-Isibonelo, i-pyridine ingasabela nge-phosphorus oxychloride (POCl3) noma i-phosphorus tetrachloride (PCl4) ngaphansi komkhathi ongasebenzi, okulandelwa ukwelashwa kwe-dechlorination ukuze kutholwe umkhiqizo ohlosiwe.

4. Ulwazi Lokuphepha:

-2,5-dichloro-4-methylpyriridine iyacasula futhi idle emehlweni, isikhumba kanye nendlela yokuphefumula. Geza ngamanzi amaningi ngokushesha ngemva kokuxhumana futhi ufune usizo lwezokwelapha;

-ukusetshenziswa kufanele kugqoke amagilavu ​​okuzivikela, izibuko zokuzivikela kanye nemaski okuzivikela;

-Gwema ukuthintana nama-oxidants aqinile ukuze ugweme ukusabela okuyingozi;

-Gcina kude nomlilo, ukushisa nezinto ezivuthayo.
