I-5-bromo-2-methylphenylhydrazine hydrochloride (CAS# 214915-80-7)

Intshayelelo

i-hydrochloride yi-organic compound ene-chemical formula C7H8BrN2 · HCl. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:

Indalo:

-Imbonakalo: iCrystal engenambala okanye etyheli

-Indawo yokunyibilika: Malunga ne-155-160 degrees Celsius

-Ukunyibilika: Inyibilika kancinci emanzini, ukunyibilika ngcono kwi-ethanol kunye ne-ether

-Ityhefu: Ikhompawundi inomlinganiselo othile wetyhefu kwaye kufuneka iphathwe ngononophelo kwaye inqande ukuphefumla kunye nokunxibelelana kwesikhumba.

Sebenzisa:

-i-hydrochloride ingasetyenziselwa ukudibanisa ezinye iikhompawundi zezinto eziphilayo, ezifana ne-pharmaceutical intermediates kunye nedayi.

-Inokuthi isetyenziswe njengento ebalulekileyo ye-organic synthesis reagent, esebenza njenge-catalyst kwi-organic synthesis reactions.

Indlela:

Indlela yokulungiselela i-hydrochloride inokuqhutywa ngamanyathelo alandelayo:

1. Dissolve 2-bromo-5-methylaniline kwi-ethanol

2. Yongeza i-nitrite ye-sodium kunye ne-hydrochloric acid, i-diazotization reaction kwiqondo lokushisa

3. Yongeza i-ether ene-anhydrous yokutsalwa, kwaye usebenzise igesi ye-hydrogen chloride ukuhluza umaleko we-ether ukufumana imveliso.

4. Ekugqibeleni, i-hydrochloride ifunyenwe nge-crystallization

Ulwazi ngoKhuseleko:

-I-compound inetyhefu kwaye kufuneka iphathwe ngononophelo

-Nika ingqalelo kumanyathelo okukhusela xa usebenzisa kunye nokugcina, ugweme ukuphefumla okanye ukudibanisa nolusu kunye namehlo

-Nika ingqalelo kwiimeko ezintle zomoya ngexesha lokusebenza

-Ukuba ngengozi udibana nesikhumba okanye amehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune uncedo lwezonyango

-Nceda ugcine kwaye uphathe i-compound ngokufanelekileyo, ugweme ukudibanisa ne-oxidants kunye ne-acids eqinile ukukhusela iimeko ezingakhuselekanga.
