Mawu Oyamba
1,3-Difluorobenzene ndi organic pawiri. Zotsatirazi ndizofotokozera mwatsatanetsatane za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 1,3-difluorobenzene:
Ubwino:
1,3-Difluorobenzene ndi gulu la organofluorine lomwe lili ndi kukhazikika kwa mankhwala. Sichikhoza kuyaka koma imakhudzidwa ndi ma oxidizing amphamvu. 1,3-Difluorobenzene imasungunuka mu zosungunulira za organic monga ethanol, etha ndi chloroform, komanso osasungunuka m'madzi.
Gwiritsani ntchito:
1,3-difluorobenzene ili ndi phindu linalake la organic synthesis. Angagwiritsidwe ntchito ngati reagent anachita mu organic synthesis, mwachitsanzo monga fluorinating reagent kwa onunkhira mankhwala. 1,3-difluorobenzene itha kugwiritsidwanso ntchito popanga zida za fulorosenti, kukonza zida za organic optoelectronic ndi magawo ena.
Njira:
1,3-Difluorobenzene ikhoza kukonzedwa ndi fluorination ya benzene. Njira zokonzekera zomwe zimagwiritsidwa ntchito nthawi zambiri ndi hydrogen fluoride ngati fluorinating agent kapena kugwiritsa ntchito ma ferrous fluoride complexes kuti apange fluorination.
Zambiri Zachitetezo:
Njira zotsatirazi zodzitetezera ziyenera kutsatiridwa mukamagwiritsa ntchito 1,3-difluorobenzene:
1.1,3-Difluorobenzene ili ndi kawopsedwe kena kake, komwe kungayambitse kuvulaza khungu, kupuma mpweya kapena kuyamwa mwangozi. Zida zodzitetezera zoyenerera monga magolovesi, zovala zodzitetezera m'maso, ndi masks ziyenera kuvalidwa mukamagwiritsa ntchito.
2. Pewani kukhudzana ndi oxidizing amphamvu kuti mupewe moto kapena kuphulika.
3. Iyenera kusungidwa pamalo owuma, ozizira komanso mpweya wabwino, kutali ndi moto ndi zipangizo zoyaka.
5. Pewani kusakanikirana ndi mankhwala ena ndipo khalani kutali ndi ana ndi anthu omwe sadziwa kugwira ntchito.
