2-Fluorobenzonitrile (CAS# 394-47-8)
Kotsi le Polokeho
| Likhoutu tsa Kotsi | R22 – E kotsi ha e kwetswe R37/38 – E tenang tsamaiso ya ho hema le letlalo. R41 – Kotsi ya tshenyo e kgolo mahlong R36/37/38 – Ho tena mahlo, tsamaiso ya ho hema le letlalo. R20/21/22 – E kotsi ka ho hema, ho kopana le letlalo le ha e koetsoe. |
| Tlhaloso ea Tšireletseho | S26 - Ha u kopana le mahlo, hlatsoa hang-hang ka metsi a mangata 'me u batle keletso ea bongaka. S39 - Apara ts'ireletso ea mahlo / sefahleho. S36/37/39 - Apara liaparo tse loketseng tsa tšireletso, liatlana le tšireletso ea mahlo / sefahleho. S36 - Apara liaparo tse loketseng tsa tšireletso. |
2-Fluorobenzonitrile(CAS#394-47-8) Selelekela
2-Fluorobenzonitrileke motsoako oa lintho tse phelang. Ke mokelikeli o mosehla o se nang 'mala ho isa ho o mosehla o nang le monko o matla. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea 2-fluorobenzonitrile:
Thepa:
- 2-Fluorobenzonitrile ke mokelikeli o sa tsitsang ka metsing 'me o na le khatello e tlaase ea mouoane mocheso oa kamore.
- E na le solubility e ntle 'me e ka qhibiliha ka har'a metsoako e mengata ea tlhaho e kang ethanol, acetone le dimethylformamide.
- E tsitsitse moeeng, empa lik'hemik'hale tse kotsi tsa lik'hemik'hale li ka 'na tsa etsahala ha li futhumala ho ea holimo kapa li kopana le li-oxidants tse matla.
Lisebelisoa:
- E ka boela ea sebelisoa e le thepa e tala bakeng sa ho roala, dae le litlolo tse nkhang hamonate.
Mokhoa oa ho itokisa:
- Ho na le mekhoa e 'meli e meholo ea ho lokisa 2-fluorobenzonitrile: mokhoa oa ho fetola cyanide le mokhoa oa ho fetola fluoride.
- Mokhoa oa ho fetola cyanide o bolela ho nkela sehlopha sa cyano sebaka sa reng ea benzene le ho kenya liathomo tsa fluorine ho nkela sehlopha sa cyano sebaka.
- Fluoride substitution method e bolela ts'ebeliso ea fluoride e le ntho e tala, e arabelang ka chlorine, bromine kapa haloform ho lesale la benzene, ho nkela chlorine, bromine kapa haloform sebaka ka fluorine ho fumana 2-fluorobenzonitrile.
Lintlha tsa Tšireletseho:
- 2-Fluorobenzonitrile e chefo 'meleng oa motho. Ka kopo qoba ho kopana ka ho toba le letlalo, mahlo le ho hema mouoane oa lona.
- Apara lisebelisoa tsa ts'ireletso tse nepahetseng joalo ka liatlana, likhalase tsa tšireletso le liaparo tsa ts'ireletso nakong ea ts'ebetso.
- Ha e bolokoa, 2-fluorobenzonitrile e lokela ho kenngoa ka sejaneng se tiisitsoeng, hole le mollo le li-oxidants, 'me e bolokoe hantle ho qoba ho lutla le tšusumetso.
