Isingeniso
Kuyinhlanganisela yemvelo enefomula yamakhemikhali i-C7H7N2O3. Okulandelayo incazelo yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwenhlanganisela:
Imvelo:
-Ukubukeka: Kuyikristalu ephuzi noma impushana.
-Ukunyibilika: Kucishe kuncibilike emanzini futhi kuncibilika kalula kuzincibilikisi zemvelo ezifana ne-ethanol, i-chloroform ne-dimethyl sulfoxide.
-Indawo yokuncibilika: Iphuzu layo lokuncibilika lilinganiselwa ku-135-137 degrees Celsius.
-Izakhiwo zamakhemikhali: Kuyinhlanganisela enamakha ene-nitrogen enomsebenzi othile wokusabela kwamakhemikhali.
Sebenzisa:
-Ingasetshenziswa njengendawo ephakathi yokuhlanganiswa kwamanye ama-organic compounds.
-Ingasetshenziswa njengempahla yokubulala izinambuzane kanye nemithi yokubulala ukhula emkhakheni wezolimo.
Indlela:
-ingalungiswa ngokusabela i-2-methylpyridine nge-nitric acid. Izinyathelo ezithile zimi kanje: ukuhlakaza i-2-methylpyridine ku-ethanol, ukwengeza i-nitric acid egxilile, nokuthola umkhiqizo nge-crystallization ngemva kokusabela.
Ulwazi Lokuphepha:
-Kuyingozi kakhulu ukuthintana nesikhumba, ukuhogela umoya noma ngemuva kokuwuphuza.
-Gwema ukuthintana kwesikhumba nokuhogela lapho uthintana. Gqoka izibuko namagilavu uma kunesidingo.
-Bheka izinqubo zokusebenza eziphephile ngesikhathi sokuphatha nokugcina futhi uvale ngokufanelekile.
-uma kunesidingo, bheka ku-Chemical Safety Data Sheet (MSDS) ukuze uthole ukwaziswa okwengeziwe kokuphepha.
