Okwu mmalite
- Ọdịdị: kristal ọcha ma ọ bụ ìhè edo edo siri ike.
- Ebe mgbaze: ihe dịka 40-42 ℃.
- Ebe esi mmiri: ihe dịka 163-165 ℃.
-Njupụta: ihe dịka 1.435g/cm³.
-Solubility: Ọ na-agbaze na ụfọdụ ihe mgbaze organic nkịtị, dị ka ethanol, chloroform na dichloromethane.
Jiri:
A na-ejikarị ya maka mmeghachi omume kemịkalụ na njikọ organic. Enwere ike iji ya dị ka ihe dị n'etiti agba agba fluorescent, dị ka ihe eji eme ihe n'ọhịa ọgwụ, na ubi ugbo maka nkwadebe nke pesticides.
Ụzọ nkwadebe:
Enwere ike ịkwadebe ya site na chlorination, usoro benzaldehyde fluorinated. Usoro nkwadebe kpọmkwem bụ nke a:
1. N'okpuru ọnọdụ kwesịrị ekwesị, a na-agbakwunye hydrofluoric acid na benzaldehyde iji mee ka ọ nweta mmeghachi omume fluorination.
2. Mgbe mmeghachi omume ahụ gasịrị, a na-agbakwunye hydrogen chloride na chlorinate ngwaahịa fluorinated.
3. Mee usoro nchacha kwesịrị ekwesị iji nweta phosphonium dị ọcha.
Ozi nchekwa:
-bụ ihe na-emerụ ahụ, nwere ike ịkpasu iwe na imebi ahụ mmadụ. Yiri gloves nchebe, iko na akụrụngwa nchebe iku ume mgbe ọ dị mkpa.
-Ezere ikuru uzuzu ya ma ọ bụ gas, ma zere imetụ akpụkpọ ahụ na anya anya.
-N'oge nchekwa na ojiji, ekwesịrị ịhụ usoro nchekwa kemịkalụ, na ọnọdụ ikuku kwesịrị ekwesị kwesịrị idobe.
-Maka ikpughe na mberede ma ọ bụ iri nri, chọọ nlekọta ahụike ozugbo wee nye data nchekwa kwesịrị ekwesị.
