Phenylacetylene(CAS#536-74-3) hlahisa
boleng
Phenacetylene ke motsoako oa manyolo. Mona ke tse ling tsa thepa ea phenylacetylene:
1. Lintho tsa 'mele: Phenacetylene ke mokelikeli o se nang 'mala o fetohang mocheso oa kamore.
2. Lintho tsa lik'hemik'hale: Phenylacetylene e ka ba le liphetoho tse ngata tse amanang le carbon-carbon triple bonds. E ka ba le karabelo ea tlatsetso ka li-halogen, joalo ka karabelo ea tlatsetso ka chlorine ho theha phenylacetylene dichloride. Phenacetylene e ka boela ea e-ba le karabelo ea phokotso, e sebetsanang le hydrogen ka pel'a mokelikeli oa ho etsa styrene. Phenylacetylene e ka boela ea phethahatsa karabelo ea li-reagents tsa ammonia ho hlahisa lihlahisoa tse tsamaisanang le tsona.
3. Ho tsitsa: The carbon-carbon triple bond ea phenylacetylene e etsa hore e be le boemo bo phahameng ba ho se sebetse. E batla e sa tsitsa, 'me e atisa ho ba le maikutlo a itlelang feela a polymerization. Phenacetylene e boetse e chesa haholo 'me e lokela ho qojoa hore e se ke ea kopana le li-oxidizing agents tse matla le mehloli ea mollo.
Tsena ke tse ling tsa thepa ea mantlha ea phenylacetylene, e nang le boleng ba ts'ebeliso ea bohlokoa ho organic synthesis, mahlale a thepa le likarolo tse ling.
Boitsebiso ba Tšireletseho
Phenacetylene. Lintlha tse ling tsa polokeho mabapi le phenylacetylene ke tsena:
1. Chefo: Phenylacetylene e na le chefo e itseng 'me e ka kena' meleng oa motho ka ho hema, ho kopana le letlalo, kapa ho e noa. Ho pepesehela nako e telele kapa ho tsepamisa mohopolo haholo ho ka ba le litlamorao tse mpe ho phefumoloha, tsamaiso ea methapo le sebete.
2. Ho phatloha ha mollo: Phenylacetylene ke ntho e tukang e khonang ho etsa motsoako o phatlohang o nang le oksijene moeeng. Ho pepesehela malakabe a bulehileng, mocheso o phahameng, kapa mehloli e tukang ho ka baka mollo kapa ho phatloha. Ho kopana le lintho tse kang li-oxidants le li-acid tse matla li lokela ho qojoa.
3. Qoba ho hema: Phenylacetylene e na le monko o hlabang o ka bakang molikoalikoane, ho otsela le ho se phele hantle. Phefumoloho e ntle e lokela ho bolokoa nakong ea ts'ebetso le ho hema ka kotloloho ho mouoane kapa likhase tsa phenylacetylene ho lokela ho qojoa.
4. Tšireletso ea ho ikopanya: Ha u tšoara phenylacetylene, apara li-gloves tse sireletsang, likhalase le liaparo tse loketseng tse sireletsang ho qoba ho kopana le letlalo le mahlo.
5. Ho boloka le ho tšoara: Phenylacetylene e lokela ho bolokoa sebakeng se pholileng, se nang le moea o motle, hole le mehloli ea mollo le malakabe a bulehileng. Setshelo se lokela ho hlahlojwa bakeng sa boemo bo botle pele se sebediswa. Ts'ebetso ea ts'ebetso e lokela ho latela mekhoa e sireletsehileng ea ts'ebetso ho qoba litlhase le litefiso tsa electrostatic.
Lisebelisoa le mekhoa ea ho kopanya
Phenacetylene ke motsoako oa manyolo. E entsoe ka reng ea benzene e hokahantsoeng le sehlopha sa acetylene (EtC≡CH).
Phenacetylene e na le mefuta e mengata ea likopo ho organic synthesis. Mona ke tse ling tsa lisebelisoa tsa mantlha:
Tšimoloho ea chefo e bolaeang likokonyana: phenylacetylene ke karolo ea bohlokoa ea mahareng ha ho etsoa chefo e sebelisoang hangata, joalo ka dichlor.
Lisebelisoa tsa Optical: Phenylacetylene e ka sebelisoa karabelong ea photopolymerization, joalo ka ho lokisa lisebelisoa tsa photochromic, lisebelisoa tsa photoresistive, le lisebelisoa tsa photoluminescent.
Mekhoa ea ho kopanya ea phenylacetylene lilaboratoring le liindasteri haholo-holo ke tse latelang:
Acetylene reaction: ka karabelo ea arylation le acetylenylation reaction ea lesale la benzene, selikalikoe sa benzene le sehlopha sa acetylene li hokahane ho lokisa phenylacetylene.
Enol rearrangement reaction: Enol e leng selikalikoeng sa benzene e ts'oaroa le acetylenol, 'me karabelo ea ho hlophisa bocha e hlaha ho hlahisa phenylacetylene.
Alkylation reaction: ho kentsoe reng ea benzene
