Mawu Oyamba
Ndi organic pawiri. Njira yake yamakina ndi C6H6BrFN ndipo kulemera kwake ndi 188.03g/mol.
Pagululi ndi madzi achikasu otuwa opanda mtundu komanso onunkhira. Ili ndi malo osungunuka a -2 ° C ndi malo otentha a 80-82 ° C. Ikhoza kusungunuka mu zosungunulira za organic monga ethanol ndi dimethylformamide pa kutentha kwabwino.
Itha kugwiritsidwa ntchito ngati wapakatikati mu kaphatikizidwe organic ndipo chimagwiritsidwa ntchito m'minda ya mankhwala, mankhwala ndi zipangizo sayansi. Itha kugwiritsidwa ntchito popanga zinthu zina za acidic, kaphatikizidwe ka glyphosate, maikulosikopu ndi zolemba za fulorosenti, etc.
Phosphor imatha kukonzedwa poyambitsa maatomu a bromine ndi fluorine mu picoline. Njira imodzi yodziwika bwino ndiyo kugwiritsa ntchito mpweya wa bromine ndi fluorine pochita ndi 2-methylpyridine. Zomwe zimafunika kuti zichitike muzosungunulira zoyenera kuchita ndipo zimafuna Kutentha ndi kusonkhezera.
Ponena za chitetezo, khalani kutali ndi moto ndi kutentha kwakukulu. Gwiritsani ntchito magolovesi oteteza oyenerera komanso chitetezo chamaso. Mukakhudza khungu kapena maso, muzimutsuka mwamsanga ndi madzi ambiri ndikupempha thandizo lachipatala. Malamulo okhudzana ndi chitetezo cha mankhwala ayenera kuwonedwa panthawi yosungira ndi kusamalira.
