Intshayelelo
I-Acid, ekwabizwa ngokuba yi-asidi, yi-organic compound. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
-Imbonakalo: iasidi ngumgubo omhlophe wekristale.
-Ifomula yemolekyuli: C6H4BrNO2.
-Ubunzima bemolekyuli: 206.008g / mol.
-Indawo yokunyibilika: malunga ne-132-136 degrees Celsius.
-Izinzile kwiqondo lokushisa kunye ne-soluble kwezinye izinyibilikisi eziphilayo.
Sebenzisa:
I-asidi isoloko isetyenziswa njengento ekrwada okanye ephakathi kwi-organic synthesis.
-Ingasetyenziselwa ukudibanisa uchungechunge lwe-nitrogen-containing heterocyclic compounds, njenge-pyridine kunye ne-pyridine derivatives.
-Ingasetyenziselwa ukulungisa i-biologically active compounds, ezifana ne-pesticides, iziyobisi kunye nedayi.
Indlela yokulungiselela:
-¾ iasidi idla ngokulungiswa ngokusabela kwe-asidi ye-bromo-nicotinic. Indlela yokudibanisa eqhelekileyo kukusabela i-nicotinic acid kunye ne-bromoethanol phantsi kweemeko ze-alkaline, ilandelwa yi-acidification ukufumana imveliso.
Ulwazi ngoKhuseleko:
-i-asidi kufuneka ilandele iinkqubo zokhuseleko lwebhubhoratri jikelele ngexesha lokusetyenziswa.
-Inokubangela ukucaphuka kwamehlo, ulusu kunye nepheshana lokuphefumula, ngoko ukudibanisa ngokuthe ngqo kufuneka kugwenywe ngexesha lokusebenza.
-kwindawo yokugcina kunye nokusetyenziswa kufuneka ingqalelo ukuphepha ukudibanisa ne-oxidants, i-acids eqinile kunye nezinye izinto, ukwenzela ukuphepha izinto ezinobungozi okanye ukuphendula.
-Ukuba kuyimfuneko, sebenza kwindawo enomoya, unxibe iiglavu zokukhusela, iiglasi zokukhusela kunye neemaski zokukhusela. Ukuba uphefumlelwe okanye utyhilekile, funa iingcebiso kugqirha.
