Selelekela

M-fluorobenzaldehyde. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea m-fluorobenzaldehyde:

 

Boleng:

- Ponahalo: M-fluorobenzaldehyde ke mokelikeli o se nang 'mala kapa o mosehla.

- Solubility: E qhibiliha ka har'a lihlapolli tsa tlhaho tse kang ethers, joala le joala ba ether.

 

Sebelisa:

- Likokoana-hloko tse sebetsang hantle haholo: M-fluorobenzaldehyde, e le motsoako oa motsoako oa organic synthesis, e sebelisoa haholo tšimong ea temo ho lokisa likokoanyana tse sebetsang hantle, tse kang COFLUOROETHYLENE kapa lisebelisoa tse ling tse tala.

- Tšebeliso ea lik'hemik'hale: M-fluorobenzaldehyde e atisa ho sebelisoa e le motsoako oa motsoako oa lintho tse phelang 'me e ka sebelisoa ho lokisa metsoako e meng, e kang m-fluorophenyl oxalate le camphor ethanol.

 

Mokhoa:

- Ho na le mekhoa e 'meli ea mantlha ea ho lokisa m-fluorobenzaldehyde: mokhoa oa fluoride le mokhoa oa fluorination. Har'a bona, mokhoa oa fluoride o fumanoa ka ho arabela m-fluorophenylmagnesium fluoride ka formaldehyde; Mokhoa oa fluorination o fumanoa ka hydrolysis ea p-toluene le antimony trichloride sebakeng sa chlorine.

 

Lintlha tsa Tšireletseho:

- Ho bohlokoa haholo hore m-fluorobenzaldehyde ke ntho e chefo 'me e lokela ho sebelisoa maemong a nang le moea o motle le lisebelisoa tse loketseng tsa ho itšireletsa li lokela ho apesoa.

- Nakong ea tšebeliso kapa polokelo, qoba ho tsoakana le li-oxidants tse matla, lino tse tahang le lintho tse ling ho qoba liketso tse kotsi.

- Boloka setshelo se tiisitsoe ka thata 'me se le hole le mehloli ea mollo le mocheso ha u se boloka.
