Isingeniso
Kuyinhlanganisela yemvelo enefomula yamakhemikhali i-C8H9NO3. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: Ayinambala ikristale ekhanyayo ephuzi.
-I-Solubility: Icishe ingancibiliki emanzini, kodwa inokuncibilika kangcono kuzincibilikisi zemvelo ezifana ne-ethanol ne-dimethylformamide.
-Indawo yokuncibilika: Iphuzu lokuncibilika licishe libe ngama-72-75 degrees Celsius.
Sebenzisa:
-Chemical synthesis: Kuyinhlanganisela evame ukusetshenziswa ephakathi engasetshenziswa ukuhlanganisa ezinye izinhlanganisela eziphilayo.
-Research: Ingasetshenziselwa ukusabela kwe-organic synthesis kanye nolunye ucwaningo lwaselabhorethri.
Indlela Yokulungiselela:
I-synthesis ingenziwa ngezinyathelo ezilandelayo:
1. Okokuqala, i-2-methyloxy-5-nitropyridine itholakala ngokusabela i-2-methyloxy-5-nitropyridine nge-nitric acid.
2. Bese uphendula i-2-methoxy-5-nitropyridine nge-reagent ye-methylating (njenge-methyl sodium iodide) ukuze uthole umkhiqizo wokugcina.
Ulwazi Lokuphepha:
Idatha yokuphepha inomkhawulo, kodwa ingaba yingozi kubantu nasendaweni ezungezile. Lapho usebenzisa, kufanele ulandele inkambiso efanele yaselabhorethri, futhi uthathe izinyathelo zokuzivikela ezidingekayo, njengokugqoka izibuko zokuzivikela namagilavu. Ngaphezu kwalokho, inhlanganisela kufanele igcinwe futhi ilahlwe ngendlela efanele ukuze kuvinjelwe ukungcoliswa kwemvelo.
