Intshayelelo

I-Ethyl 2, i-organic compound kunye ne-chemical formula C7H5Cl2NO2. Lulwelo olungenambala ukuya kumthubi olunevumba elinukayo.

Le khompawundi isoloko isetyenziswa njengento ephakathi kunye nekrwada, kwaye inoluhlu olubanzi lwezicelo kwi-organic synthesis. Ihlala isetyenziselwa ukulungiswa kwee-pesticides, amayeza kunye nedayi kunye nezinye iikhompawundi. Ukongeza, inokusetyenziselwa ukufunda ukuphendula kweekhemikhali kunye neempawu ze-ethyl nicotinate.

Indlela yokulungiselela i-ethyl 2 kukusabela kwi-2,6-dichloropyridine-3-fomic acid kunye ne-ethanol, ngokuqhelekileyo phantsi kweemeko ze-acidic.

ethyl 2, kukho umngcipheko othile wokhuseleko. Yikhemikhali ecaphukisayo enokubangela ukucaphuka kwamehlo, ulusu kunye nenkqubo yokuphefumla. Xa uphatha, nxiba izixhobo zokukhusela ukuphefumula, iiglasi zokukhusela, iiglavu zokukhusela kunye nezixhobo zokukhusela iinyawo. Ukongeza, nayo inomngcipheko womlilo, kufuneka ibe kude nomlilo ovulekileyo kunye nobushushu obuphezulu.

Ngenxa yezizathu zokhuseleko, xa usebenzisa i-ethyl 2, landela iinkqubo zebhubhoratri ezichanekileyo kwaye usebenze kwindawo enomoya omhle.

Ngaphambili: Tetrapropyl ammonium chloride (CAS# 5810-42-4)

Okulandelayo: D-Glutamine (CAS# 5959-95-5)
