Intshayelelo
I-Acid yi-organic compound kunye ne-chemical formula C6H4BrO2S.
Indalo:
-Inkangeleko: iasidi yinto eqinileyo emhlophe ukuya kumthubi.
-Ukunyibilika: Inyibilika kwi-chloroform, i-acetone kunye ne-chlorinated methane.
-Indawo yokunyibilika: malunga ne-116-118 degrees Celsius.
Sebenzisa:
-kufuneka i-asidi isoloko isetyenziswa njengento ebalulekileyo ephakathi kwi-organic synthesis.
-Ingasetyenziselwa ukwakha i-organic compounds equkethe izakhiwo zeringi ye-thiophene.
Indlela yokulungiselela: Zininzi iindlela zokwenziwa ze
-i-anacid. Enye yeendlela ezisetyenziswa ngokuqhelekileyo kukusebenzisa i-bromoacetic acid njengento eluhlaza, isabela nge-thiophene phantsi kweemeko ze-alkaline ukuvelisa i-3-bromothiophene, kwaye emva koko iqhube i-carboxylic reaction phantsi kweemeko ze-acidic.
Ulwazi ngoKhuseleko:
-i-asidi inokucaphukisa amehlo, ulusu kunye nenkqubo yokuphefumla.
-Ngexesha lokusetyenziswa, kufuneka kuthathelwe ingqalelo ukuphepha ukuphefumla uthuli okanye ukudibanisa nolusu kunye namehlo.
-Nxiba izixhobo ezifanelekileyo zokukhusela ezifana neeglavu zelebhu, iiglasi kunye nezikhuselo zobuso phambi kokuba usebenze.
-Xa udibana nesikhumba okanye amehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune unyango. Amanyathelo afanelekileyo oncedo lokuqala aya kubonelelwa ukuba kuyimfuneko.
