Okwu mmeghe dị nkenke
4-Chloro-2-fluorobenzoic acid bụ ngwakọta organic. Ndị a bụ mmalite nke akụrụngwa ya, ojiji ya, ụzọ nrụpụta ya na ozi nchekwa:
Ogo:
4-Chloro-2-fluorobenzoic acid bụ kristal siri ike, nke na-adịkarịghị agba ma ọ bụ kristal na-acha odo odo. Ọ na-adịghị agbanwe agbanwe na ụlọ okpomọkụ. Ọ nwere ekpomeekpo na-esi ísì ụtọ ma nwee ike igbari ya na ihe mgbaze organic dị ka methanol, ethanol, methylene chloride, wdg.
Jiri:
4-Chloro-2-fluorobenzoic acid nwere ọtụtụ ngwa ngwa na ụlọ ọrụ kemịkalụ. A na-ejikarị ya eme ihe dị ka ihe mmalite ma ọ bụ etiti na njikọ organic. Enwere ike iji ya dị ka nri nri maka ihe na-eme ka ihe na-emepụta ihe na ihe eletrọnịkị.
Usoro:
Enwere ike nweta 4-Chloro-2-fluorobenzoic acid site na chlorination nke p-fluorobenzoic acid. N'ozuzu, hydrogen chloride ma ọ bụ chlorous acid nwere ike meghachi omume na thionyl chloride ma ọ bụ sulfinyl chloride n'okpuru ọnọdụ acidic, na-esote mmeghachi omume na hydrogen fluoride iji nweta 4-chloro-2-fluorobenzoic acid.
