Mawu Oyamba

Benzyl bromide ndi organic pawiri yokhala ndi formula yamankhwala C7H7Br. Nazi zina zokhudzana ndi katundu, ntchito, njira zokonzekera ndi chitetezo cha benzyl bromide:

 

Ubwino:

Benzyl bromide ndi madzi opanda mtundu okhala ndi fungo lamphamvu lomwe limakhala lotentha kwambiri. Kachulukidwe ake ndi 1.44g/mLat 20 °C, kuwira kwake ndi 198-199 °C(lit.), ndipo malo ake osungunuka ndi -3 °C. Ikhoza kusungunuka mu zosungunulira zambiri za organic ndipo sizisungunuka m'madzi.

 

Gwiritsani ntchito:

Benzyl bromide ili ndi ntchito zosiyanasiyana. Nthawi zambiri amagwiritsidwa ntchito mu organic synthesis ngati reagent pazochita. Itha kugwiritsidwa ntchito pokonza ma esters, ethers, acid chlorides, ether ketones, ndi zinthu zina zachilengedwe. Kuphatikiza apo, benzyl bromide imagwiritsidwanso ntchito ngati chothandizira nkhuku, chotsitsimutsa kuwala, utomoni wochizira, ndi retardant lawi pokonzekera.

 

Njira:

Benzyl bromide imatha kukonzedwa ndi zomwe benzyl bromide ndi bromine pansi pamikhalidwe yamchere. Chofunikira ndikuwonjezera bromine ku benzyl bromide, ndikuwonjezera alkali (monga sodium hydroxide) kuti mupeze benzyl bromide pambuyo pochita.

 

Zambiri Zachitetezo:

Benzyl bromide ndi mankhwala omwe ali ndi kawopsedwe kena. Zimakhudza maso, khungu, ndi kupuma, choncho muyenera kusamala mukamagwiritsa ntchito zida zodzitetezera monga magolovesi, magalasi, ndi zishango zakumaso mukakhudza. Kuphatikiza apo, benzyl bromide imapangitsanso ngozi yoyaka moto ndipo iyenera kupewedwa kuti isakhudzidwe ndi zoyaka komanso kusungidwa kutali ndi malawi otseguka. Posunga ndi kugwira benzyl bromide, tsatirani njira zoyenera zogwirira ntchito zotetezeka ndikuzisunga pamalo otetezeka ndipo pewani kusakaniza ndi mankhwala ena.
