Intshayelelo
I-4-Methyl-2-nitroaniline, eyaziwa ngokuba yi-methyl yellow, i-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: I-methyl etyheli yikristale etyheli okanye umgubo wekristale.
- Ukunyibilika: Imethyl etyheli iphantse yanganyibiliki emanzini, kodwa inyibilika kwizinto ezininzi ezinyibilikayo ezifana neealkoholi, ii-ethers, kunye nebenzene.
Sebenzisa:
- I-Chemical intermediates: I-Methyl yellow idla ngokusetyenziswa njengento ebalulekileyo ephakathi kwi-synthesis yedayi, i-pigments, i-fluorescents kunye ne-organic optoelectronic materials.
- I-Biomarkers: I-Methyl yellow ingasetyenziselwa njenge-labeler ye-fluorescent yeeseli kunye ne-biomolecules, esetyenziswa kwiimvavanyo zezinto eziphilayo kunye nemimandla yezonyango.
- I-Enamel kunye ne-ceramic pigments: I-Methyl yellow ingasetyenziselwa njengombala we-enamel kunye neeseramics.
Indlela:
- I-Methyl yellow ilungiswe ngeendlela ezahlukeneyo, kwaye enye yeendlela eziqhelekileyo kukudibanisa nge-methylation ye-nitroaniline. Oku kunokufumaneka ngokusabela kwe-methanol kunye ne-thionyl chloride phambi kwe-catalyst ye-asidi.
Ulwazi ngoKhuseleko:
- I-Methyl yellow yikhompawundi enetyhefu ecaphukisayo kwaye enokuba yingozi ebantwini kunye nokusingqongileyo.
-Izixhobo zokukhusela zomntu ezifana neeglavu zokukhusela, iiglasi kunye neegawuni ziyafuneka xa usebenza.
- Kuphephe ukuphefumla, ukudibana nesikhumba kunye namehlo, kuphephe ukuntywila, kwaye usebenzise umoya ofanelekileyo ukuba kuyimfuneko.
- Xa ugcina kwaye uphethe i-methyl yellow, landela iinkqubo ezifanelekileyo zokusebenza kunye nemimiselo yokhuseleko.
