Re hlahisa sehlahisoa sa rona sa morao-rao sa 4-Fluorobenzoylacetonitrile, motsoako o batloang haholo indastering ea meriana le ea lik'hemik'hale. Motsoako ona o ncha o 'nile oa sebelisoa haholo ha ho etsoa metsoako e mengata ea lintho tse phelang, e leng se etsang hore e be karolo ea bohlokoa moralong le ntlafatsong ea lithethefatsi.
Foromo ea lik'hemik'hale ea 4-Fluorobenzoylacetonitrile ke C9H6FNO, 'me e na le boima ba molek'hule ea 163.15 g/mol. Nomoro ea eona ea CAS ke 4640-67-9, 'me ke kristale e 'mala o mosehla kapa oa lamunu e nang le botsitso bo botle le bophelo ba lishelefo.
Ho hloeka ha sehlahisoa sa rona ke 99%, ho etsa hore se tšoanelehe bakeng sa lits'ebetso tse fapaneng. E na le ntlha e belang ea 298-300 ° C, 'me ntlha ea ho qhibiliha ha eona e tloha ho 69°C ho ea ho 72°C. E qhibiliha ka metsoako e tloaelehileng ea tlhaho e kang ethanol, ether le dichloromethane, e leng se etsang hore ho be bonolo ho e tšoara le ho e sebelisa.
O mong oa melemo ea bohlokoa ea 4-Fluorobenzoylacetonitrile ke ho feto-fetoha ha eona ho organic synthesis. E sebetsa e le moaho oa ho kopanya metsoako e fapaneng ea lintho tse phelang tse kang 4-Fluorobenzaldehyde, 4-fluoro-2-hydroxymethylbenzoic acid, le 4-Fluorobenzoic acid. Ho feto-fetoha hona ho etsa hore e be motsoako oa bohlokoa indastering ea meriana, moo e sebelisoang ho rala le nts'etsopele ea lithethefatsi.
Ntle le meriana, 4-Fluorobenzoylacetonitrile e boetse e sebelisoa ho hlahisa lik'hemik'hale tsa agrochemicals, litlolo tse nkhang hamonate le lidae. E boetse e sebelisoa e le reagent bakeng sa tlhahlobo ea li-amino acid le liprotheine indastering ea lik'hemik'hale.
Joalo ka k'hamphani, re ikitlaelletsa ho fana ka lihlahisoa tsa boleng bo holimo tse fihlelang litlhoko tsa bareki ba rona. Sehlahisoa sa rona sa 4-Fluorobenzoylacetonitrile se etsoa tlas'a mehato e tiileng ea taolo ea boleng ho netefatsa bohloeki le boleng ba sona. Re motlotlo ka bokhoni ba rona ba ho fa bareki ba rona sehlahisoa se lumellanang le se ka tšeptjoang.
Qetellong, 4-Fluorobenzoylacetonitrile ke motsoako oa bohlokoa indastering ea meriana le ea lik'hemik'hale, e nang le mekhoa e mengata ea ho sebelisa lintho tse phelang. Bohloeki ba eona bo phahameng le botsitso bo etsa hore e be khetho e ratoang molemong oa moralo le nts'etsopele ea lithethefatsi. Ikopanye le rona kajeno bakeng sa 4-Fluorobenzoylacetonitrile ea boleng bo holimo e fihlelang litlhoko tsa hau tsa tlhahiso.
