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

Isingeniso

i-hydrochloride iyinhlanganisela ye-organic enefomula yamakhemikhali C7H8BrN2 · HCl. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:

Imvelo:

-Ukubukeka: Ikristalu engenambala noma ephuzi

-Indawo yokuncibilika: Cishe ku-155-160 degrees Celsius

-Ukunyibilika: Kuncibilika kancane emanzini, ukuncibilika okungcono ku-ethanol ne-ether

-Ubuthi: I-compound inezinga elithile lobuthi futhi kufanele iphathwe ngokucophelela futhi igweme ukuhogela kanye nokuthinta isikhumba.

Sebenzisa:

-i-hydrochloride ingasetshenziswa ukwenza amanye ama-organic compounds, njengama-intermediate emithi kanye namadayi.

-Ingasetshenziswa futhi njenge-reagent ebalulekile ye-organic synthesis, esebenza njenge-catalyst in organic synthesis reactions.

Indlela:

Indlela yokulungiselela i-hydrochloride ingenziwa ngezinyathelo ezilandelayo:

1. Chaza i-2-bromo-5-methylaniline ku-ethanol

2. Engeza i-sodium nitrite ne-hydrochloric acid, ukusabela kwe-diazotization ekamelweni lokushisa

3. Engeza i-ether engamanzi ukuze uyikhiphe, bese usebenzisa igesi ye-hydrogen chloride ukuze ugcwalise ungqimba lwe-ether ukuze uthole umkhiqizo.

4. Ekugcineni, i-hydrochloride itholakala nge-crystallization

Ulwazi Lokuphepha:

-Inhlanganisela inobuthi futhi kufanele iphathwe ngokucophelela

-Naka izinyathelo zokuzivikela lapho usebenzisa futhi ugcina, gwema ukuhogela umoya noma ukuthinta isikhumba namehlo

-Naka izimo ezinhle zokungenisa umoya ngesikhathi sokusebenza

-Uma uhlangana nesikhumba noma amehlo ngephutha, geza ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha

-Sicela ugcine futhi uphathe i-compound ngendlela efanele, gwema ukuthintana nama-oxidants nama-acids aqinile ukuvimbela izimo ezingaphephile
