Nhanganyaya

3,4-Difluorobenzoic asidhi. Iyi inotevera sumo kune hunhu hwayo, kushandiswa, nzira yekugadzira uye ruzivo rwekuchengetedza:

Hunhu:

- 3,4-Difluorobenzoic acid ikristaro chena yakasimba uye inonhuwa.

-Iyo yakasimba pakupisa kwekamuri uye inogona kunyungudika muorganic solvents senge madoro, ethers, nezvimwewo, uye ine mashoma solubility mumvura.

- 3,4-Difluorobenzoic acid ine acidic uye inopindirana nealkali kuita munyu unoenderana.

Shandisa:

- 3,4-difluorobenzoic asidhi inoshandiswa zvakanyanya seyakakosha yepakati uye mbishi zvinhu muorganic synthesis.

Nzira:

- Kune nzira dzakawanda dzekugadzirira 3,4-difluorobenzoic acid, imwe yacho inowanzoshandiswa ne fluorinating fluorinated acid.

- Iyo chaiyo nzira yekugadzirira inosanganisira kusarudzwa kwe fluorinating agent uye kutonga kwemaitiro ekuita, zvakajairika fluorinating agents ihydrogen fluoride, sulfur polyfluoride, nezvimwe.

Zvekuchengetedza

- 3,4-Difluorobenzoic acid ikemikari uye inofanira kuteverwa maererano nekuchengetedzwa kwakakodzera uye makemikari akakodzera ekudzivirira.

- Inogona kunge iine zvinogumbura pameso, ganda, uye turakiti rekufema uye inofanira kugezwa nekukurumidza mushure mekusangana.

- Panguva yekurapa, kusangana nemaoxidants akasimba uye maasidhi akasimba anofanira kudziviswa kudzivirira maitiro ane ngozi.

- 3,4-Difluorobenzoic acid inofanira kuchengetwa munzvimbo inotonhorera, yakaoma, ine mhepo yakanaka, kure nemoto uye kupisa.
