Mawu Oyamba
3,5-Difluorobenzoic acid ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha gululi:
Ubwino:
- 3,5-Difluorobenzoic acid ndi kristalo wopanda mtundu kapena ufa woyera wa crystalline.
- Imakhala pafupifupi yosasungunuka m'madzi kutentha, koma imasungunuka mu zosungunulira za organic monga ethanol, ether, etc.
- Katunduyu amakhala ndi fungo lamphamvu komanso lopsa mtima.
Gwiritsani ntchito:
- 3,5-Difluorobenzoic acid imagwiritsidwa ntchito kwambiri ngati chinthu chapakatikati komanso chowongolera mu organic synthesis.
- Pawiri angagwiritsidwe ntchito fluorination anachita ndi lumikiza anachita onunkhira mankhwala mu organic kaphatikizidwe zimachitikira.
Njira:
- Njira yokonzekera 3,5-difluorobenzoic acid imatha kupezeka ndi zomwe benzoic acid ndi hydrofluoric acid pamaso pa chothandizira.
- Pazochitika, benzoic acid imasakanizidwa ndi hydrofluoric acid ndikutenthedwa, ndipo zomwe zimachitikazo zimachitika mothandizidwa ndi chothandizira kupanga 3,5-difluorobenzoic acid.
Zambiri Zachitetezo:
- 3,5-Difluorobenzoic acid ndi chigawo chokwiyitsa chomwe chingayambitse kupsa mtima pokhudzana ndi khungu ndi maso, ndipo zida zoyenera zodzitetezera ziyenera kuvala.
- Chisamaliro chiyenera kutengedwa kuti musakhudzidwe ndi mankhwala amphamvu oxidizing ndi zinthu zamchere zamphamvu mukamagwiritsa ntchito kapena kusunga mankhwalawa kuti mupewe zoopsa.
- Pewani kununkhiza nthunzi wochuluka wa 3,5-difluorobenzoic acid, chifukwa uli ndi fungo loipa.
