Mawu Oyamba

M-trifluoromethylbenzonitrile ndi organic pawiri. Zotsatirazi ndizofotokozera mwatsatanetsatane za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha gululi:

 

Ubwino:

M-trifluoromethylbenzonitrile ndi kristalo wopanda mtundu mpaka wotumbululuka wachikasu, womwe uli ndi fungo lamphamvu la benzene. Pawiri ndi sungunuka mu organic solvents monga Mowa, etha ndi methylene kolorayidi pa firiji.

 

Gwiritsani ntchito:

M-trifluoromethylbenzonitrile imagwiritsidwa ntchito kwambiri popanga organic synthesis. Itha kugwiritsidwanso ntchito popanga mankhwala ophera tizilombo ndi utoto.

 

Njira:

M-trifluoromethylbenzonitrile ikhoza kupangidwa ndi zomwe cyanide ndi trifluoromethanylation reagents. Njira yodziwika bwino ndiyo kugwiritsa ntchito boron cyanide ndi trifluoromethanyl chlorine kupanga m-trifluoromethylbenzonitrile.

 

Zambiri Zachitetezo:

M-trifluoromethylbenzonitrile ndi yokhazikika pansi pa kugwiritsidwa ntchito ndi kusungidwa kwabwinobwino, koma iyenera kusamaliridwa ndi kusamala koyenera. Zitha kukhala zokwiyitsa komanso zowononga m'maso ndi pakhungu ndipo ziyenera kutsukidwa ndi madzi ambiri mukangokhudzana. Zida zodzitetezera zoyenerera monga zovala zodzitetezera m'maso, magolovesi ndi zovala zodzitchinjiriza ziyenera kuvalidwa mukamagwiritsa ntchito. Pewani kupuma movutikira ndi kumeza. Mukamagwiritsa ntchito mankhwalawa, tsatirani malangizo okhudzana ndi chitetezo ndikuwonetsetsa kuti akugwiritsidwa ntchito pamalo abwino mpweya wabwino.
