Nhanganyaya
3,5-Difluorobenzoic acid is an organic compound. Inotevera sumo yezvivakwa, mashandisirwo, nzira dzekugadzirira uye ruzivo rwekuchengetedza kwekomputa iyi:
Hunhu:
- 3,5-Difluorobenzoic acid ikristaro isina ruvara kana chena crystalline poda.
- Inenge isinganyungudike mumvura patembiricha yekamuri, asi inonyungudika muorganic solvents senge ethanol, ether, nezvimwe.
- Mushonga une kunhuhwirira kwakasimba uye unopisa.
Shandisa:
- 3,5-Difluorobenzoic asidhi inonyanya kushandiswa seyakakosha yepakati uye reagent mune organic synthesis.
- Mushonga unogona kushandiswa mukuita fluorination uye coupling reaction yeanonhuhwirira makomisheni mune organic synthesis maitiro.
Nzira:
- Nzira yekugadzirira ye 3,5-difluorobenzoic acid inogona kuwanikwa kuburikidza nekuita kwe benzoic acid uye hydrofluoric acid pamberi pekugadzirisa.
- Mumamiriro ezvinhu ekuita, benzoic acid inosanganiswa nehydrofluoric acid uye inopisa, uye maitiro anoitwa pasi pechiito che catalyst kugadzira 3,5-difluorobenzoic acid.
Zvekuchengetedza
- 3,5-Difluorobenzoic acid inhengo inogumbura iyo inogona kukonzera kutsamwa mukubata neganda nemaziso, uye yakakodzera midziyo yekudzivirira inofanirwa kupfekwa.
-Kuchengetedza kunofanirwa kutorwa kudzivirira kusangana neakasimba oxidizing agents uye akasimba alkaline zvinhu paunenge uchishandisa kana kuchengetedza iyi koniyuta kudzivirira kuita kwengozi.
- Dzivisa kufemba mhute yakawandisa ye3,5-difluorobenzoic acid, sezvo ine hwema hunonhuwa.
