Intshayelelo
I-organic compound kunye ne-chemical formula C7H7N2O3.
Indalo:
Iqinile inombala omthubi ukuya kumthubi. Inyibilika ngakumbi kwizinyibilikisi kwaye ayinyibiliki kancinci emanzini. Inomlinganiselo othile wokutsha, kwaye xa ishushu okanye idibene nedangatye elivulekileyo liya kuvelisa initrogen oxides enetyhefu (NOx).
Sebenzisa:
Ihlala isetyenziswa kwi-organic synthesis njengento ebalulekileyo ephakathi. Ingasetyenziselwa ukuhlanganiswa kwee-pyridine compounds, ezifana ne-pesticides, iziyobisi kunye nedayi. Ukongeza, inokusetyenziswa njenge-ligand yezakhiwo zetsimbi.
Indlela:
Ngokuqhelekileyo ilungiselelwe ngokuphendula kwe-4-methyl-2-nitropyridine kunye ne-sodium hydroxide. Ukusabela ngokuqhelekileyo kuqhutyelwa kwi-solvent ephilayo kwaye imveliso inokufumaneka.
Ulwazi ngoKhuseleko:
Iyingozi kumzimba womntu. Ukudibana nolusu kunokubangela ukungezwani komzimba, kwaye ukuphefumla uthuli okanye umphunga kufuneka kuphetshwe. Xa uphathwa, amanyathelo afanelekileyo okukhusela kufuneka athathwe, njengokunxiba iiglavu, iiglasi kunye nempahla yokukhusela. Xa usetyenziswa okanye ukugcinwa, kufuneka kube kude nomlilo kunye ne-oxidant. Kwimeko yokuvuza ngengozi, shiya indawo yokuvuza ngokukhawuleza kwaye uthathe amanyathelo afanelekileyo okucoca.
