Intshayelelo
I-3,4-Dimethylhydrazine hydrochloride i-organic compound kunye ne-chemical formula C8H12N2 · HCl. Oku kulandelayo yinkcazo emfutshane yobume bayo, ukusetyenziswa, ukuqulunqwa kunye nolwazi lokhuseleko:
Indalo:
-Ukubonakala: I-3,4-Dimethylphenylhydrazine hydrochloride idla ngokungenambala kwiikristale ezimthubi.
-Ukunyibilika: Kunokunyibilika okuthile emanzini, kodwa kwakhona kunyibilika kwiialkoholi kunye nezinyibilikisi ze-ether.
-Indawo yokunyibilika: Indawo yayo yokunyibilika yi-160-162°C.
-I-Toxicity: I-3,4-Dimethylphenylhydrazine hydrochloride inobuthi obuthile kwaye kufuneka isetyenziswe ngokukhuselekileyo.
Sebenzisa:
-I-reagent ye-Chemical: I-3,4-Dimethylphenylhydrazine hydrochloride ingasetyenziselwa njenge-organic synthesis intermediate ye-synthesis yezinye iikhompawundi okanye izinto eziphathekayo.
-Uphando lwamachiza: Ikwasetyenziswa kwinkalo yophando lweyeza, njengamachiza okwenziwa kunye nezinye izinto eziphuma kwi-organic compounds.
Indlela yokulungiselela:
Indlela yokulungiselela i-3,4-Dimethylphenylhydrazine hydrochloride inokuqhutywa ngala manyathelo alandelayo:
1. Okokuqala, i-3,4-dimethylaniline ichithwa kwisixa esifanelekileyo se-alcohol solvent.
2. Emva koko, isisombululo se-hydrochloric acid sisetyenziselwa ukusabela kunye nesisombululo, kwaye i-precipitate iya kuveliswa ngeli xesha.
3. Ekugqibeleni, i-precipitate iqokelelwa kwaye yomiswe ukufumana i-3,4-Dimethylphenylhydrazine hydrochloride.
Ulwazi ngoKhuseleko:
- 3,4-Dimethylphenylhydrazine hydrochloride inomlinganiselo othile wengozi kwaye inokubangela umonakalo kwimpilo yabantu. Ngoko ke, ekusebenziseni inkqubo kufuneka ihlawule ingqalelo ukuthobela iinkqubo ezifanelekileyo zokhuseleko.
-Kufuneka ifakwe kwisitya esivaliweyo, kude nomlilo kunye ne-oxidizing agents, kwaye igcinwe kwindawo epholileyo, eyomileyo.
-Xa usebenzisa, kufuneka unxibe izixhobo ezifanelekileyo zokukhusela, ezinjengeeglavu zaselabhoratri, iiglasi kunye nedyasi yelabhoratri.
-Xa uphatha le ngqungquthela, gwema ukuphefumula uthuli okanye isisombululo sayo, kunye nokudibanisa nolusu kunye namehlo.
-Emva kokusetyenziswa, inkunkuma kufuneka ilahlwe ngokufanelekileyo kwaye imimiselo yokukhusela indawo yendawo kufuneka igcinwe.
