Isingeniso
I-N-Methyl-4-chloropyridine-2-carboxamide iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
I-N-methyl-4-chloropyridine-2-carboxamide iyikristale emhlophe noma i-crystalline powder enephunga elikhethekile. Ine-solubility enhle kanye ne-solubility ephezulu emanzini. Ine-asidi emaphakathi kuya koqinile.
Ukusetshenziswa: Ngaphezu kwalokho, ingasetshenziswa futhi njengesithako sezinto ezivikela izitshalo kanye nezibulala-zinambuzane.
Indlela:
I-N-methyl-4-chloropyridine-2-carboxamide ingalungiswa nge-methylation ye-4-chloropyridin-2-carboxamide. Izindlela eziqondile zokuhlanganisa zingashintshwa futhi zenziwe kahle njengoba kudingeka.
Ulwazi Lokuphepha:
Ukusetshenziswa nokuphathwa kwe-N-methyl-4-chloropyridin-2-carboxamide kudinga ukuthotshelwa kwezimiso zokuphepha ezifanele. Kuyinhlanganisela yezinto eziphilayo futhi akufanele ihlangane ngqo nesikhumba namehlo. Ngesikhathi sokusetshenziswa, amagilavu okuvikela afanelekile, izibuko nezingubo zokuzivikela kufanele zigqokwe. Qaphela ukuyibeka endaweni eyomile, engenamoya futhi emnyama, kude nezinto ezivuthayo kanye nama-oxidants.
