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

Mawu Oyamba

hydrochloride ndi organic pawiri ndi mankhwala chilinganizo C7H8BrN2 · HCl. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:

Chilengedwe:

-Mawonekedwe: Crystal wopanda mtundu kapena wachikasu

- Malo osungunuka: Pafupifupi 155-160 digiri Celsius

-Kusungunuka: Kusungunuka pang'ono m'madzi, kusungunuka bwino mu ethanol ndi ether

-Toxicity: Pawiriyi imakhala ndi kawopsedwe kena kake ndipo iyenera kugwiridwa mosamala ndikupewa kupuma komanso kukhudzana ndi khungu.

Gwiritsani ntchito:

-Hydrochloride angagwiritsidwe ntchito popanga mankhwala ena organic, monga mankhwala intermediates ndi utoto

- Itha kugwiritsidwanso ntchito ngati chinthu chofunikira kwambiri cha organic synthesis reagent, chomwe chimapangitsa kuti pakhale organic synthesis reaction.

Njira:

Njira yokonzekera hydrochloride ikhoza kuchitidwa ndi izi:

1. Sungunulani 2-bromo-5-methylaniline mu ethanol

2. Onjezerani sodium nitrite ndi hydrochloric acid, diazotization reaction pa kutentha kwapakati

3. Onjezani efa ya anhydrous kuti muchotse, ndiyeno gwiritsani ntchito mpweya wa hydrogen chloride kuti mukhutitse wosanjikiza wa etere kuti mupeze mankhwalawo.

4. Pomaliza, hydrochloride imapezeka ndi crystallization

Zambiri Zachitetezo:

-Chigawochi ndi chapoizoni ndipo chiyenera kugwiridwa mosamala

- Samalirani njira zodzitetezera mukamagwiritsa ntchito ndikusunga, pewani kupuma kapena kukhudzana ndi khungu ndi maso

- Samalani ndi mpweya wabwino panthawi yogwira ntchito

-Mukakhudza khungu kapena maso mwangozi, muzimutsuka msangamsanga ndi madzi ambiri ndikupempha thandizo lachipatala

-Chonde sungani ndikusamalira pawiri moyenera, pewani kukhudzana ndi ma oxidants ndi ma acid amphamvu kuti mupewe ngozi
