Mawu Oyamba
2,4,5-Trifluorobenzoic acid ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
- Maonekedwe: Ufa wopanda mtundu mpaka woyera wa crystalline
- Kusungunuka: kusungunuka pang'ono m'madzi komanso kusungunuka mu zosungunulira organic monga ma alcohols, ethers ndi ketones
- Chemical properties: Ndi asidi amphamvu omwe amalumikizana ndi alkalis, zitsulo ndi zitsulo zowonongeka.
Gwiritsani ntchito:
- 2,4,5-Trifluorobenzoic acid amagwiritsidwa ntchito makamaka ngati chofunikira chapakatikati komanso chothandizira mu kaphatikizidwe ka organic.
- Pazochita zina, zitha kugwiritsidwa ntchito ngati gwero la ayoni a fluoride ndikuchita nawo machitidwe a fluorination.
- Itha kugwiritsidwanso ntchito pokonza mankhwala ena a organofluorine.
Njira:
Pali njira zosiyanasiyana zokonzera 2,4,5-trifluorobenzoic acid, ndipo zotsatirazi ndi imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri:
- React benzoic acid ndi aluminium trifluoride kuti mupeze benzoylaluminium trifluoride.
- Kenako, benzoyl aluminium trifluoride imasinthidwa ndi madzi kapena mowa kuti ikhale hydrolyze kupereka 2,4,5-trifluorobenzoic acid.
Zambiri Zachitetezo:
- 2,4,5-Trifluorobenzoic acid imakwiyitsa khungu ndi maso, ndipo zipangizo zoyenera zotetezera zimafunika pogwira ndi kukhudzana.
- M'malo achinyezi, amatha kunyozeka ndikutulutsa mpweya woipa, womwe umayenera kugwiritsidwa ntchito pamalo olowera mpweya wabwino.
- Posunga ndi kunyamula, kukhudzana ndi ma okosijeni amphamvu, ma asidi amphamvu ndi zinthu zina kuyenera kupewedwa.
- Fufuzani kuchipatala mwamsanga ngati mutamwa kapena kupumira.
Njira zoyenera zogwirira ntchito ndi chitetezo ziyenera kutsatiridwa pogwiritsira ntchito ndi kusamalira mankhwala, ndikuwunikidwa ndikuyendetsedwa pazochitika ndi zochitika.
