I-Phenylacetylene(CAS#536-74-3) yethula
izinga
I-Phenacetylene iyinhlanganisela yezinto eziphilayo. Nazi ezinye zezakhiwo ze-phenylacetylene:
1. Izici ezingokomzimba: I-Phenacetylene iwuketshezi olungenambala oluguquguqukayo ekushiseni kwegumbi.
2. Izici zamakhemikhali: I-Phenylacetylene ingabhekana nokusabela okuningi okuhlobene ne-carbon-carbon triple bond. Ingabhekana nokusabela okungeziwe ngama-halogen, njengokusabela okungeziwe nge-chlorine ukwenza i-phenylacetylene dichloride. I-Phenacetylene nayo ingabhekana nokusabela kokunciphisa, iphendule nge-hydrogen phambi kwe-catalyst yokwenza i-styrene. I-Phenylacetylene ingakwazi futhi ukwenza ukusabela esikhundleni sama-reagents e-ammonia ukukhiqiza imikhiqizo ehambisanayo esikhundleni.
3. Ukuzinza: I-carbon-carbon triple bond ye-phenylacetylene iyenza ibe nezinga eliphezulu lokungagcwalisi. Ayizinzile uma iqhathaniswa futhi ijwayele ukuvela ngokuzenzakalela i-polymerization. I-Phenacetylene nayo ivutha kakhulu futhi kufanele igwenywe ukuthintana nama-oxidizing agents aqinile kanye nemithombo yokuthungela.
Lezi ezinye zezinto eziyisisekelo ze-phenylacetylene, ezinenani elibalulekile lokusetshenziswa ku-organic synthesis, isayensi yezinto zokwakha kanye neminye imikhakha.
Ulwazi Lokuphepha
Phenacetylene. Nansi eminye imininingwane yokuphepha mayelana ne-phenylacetylene:
1. Ubuthi: I-Phenylacetylene inobuthi obuthile futhi ingangena emzimbeni womuntu ngokuhogela, ukuthintana nesikhumba, noma ngokumunca. Ukuchayeka isikhathi eside noma ukugxila kakhulu kungase kube nemiphumela emibi ohlelweni lokuphefumula, lwezinzwa nesibindi.
2. Ukuqhuma komlilo: I-Phenylacetylene into evuthayo ekwazi ukwenza ingxube eqhumayo enomoya-mpilo emoyeni. Ukuchayeka emalangabini avulekile, amazinga okushisa aphezulu, noma imithombo yokuthungela kungaholela emlilweni noma ukuqhuma. Ukuthintana nezinto ezifana nama-oxidants nama-asidi aqinile kufanele kugwenywe.
3. Gwema ukuhogela: I-Phenylacetylene inephunga elimnandi elingase libangele isiyezi, ukozela, nokungakhululeki ekuphefumuleni. Ukungena komoya okuhle kufanele kugcinwe ngesikhathi sokusebenza futhi ukuhogela ngokuqondile komhwamuko we-phenylacetylene noma amagesi kufanele kugwenywe.
4. Ukuvikelwa kokuxhumana: Lapho uphethe i-phenylacetylene, gqoka amagilavu okuzivikela, izibuko nezingubo zokuzivikela ezifanele ukuze ugweme ukuthintana nesikhumba namehlo.
5. Ukugcinwa nokuphatha: I-Phenylacetylene kufanele igcinwe endaweni epholile, enomoya omuhle, kude nemithombo yomlilo namalangabi avulekile. Isiqukathi kufanele sihlolwe ukuthi sisesimweni esihle yini ngaphambi kokusetshenziswa. Inqubo yokubamba kufanele ilandele izinqubo zokusebenza eziphephile ukuze kugwenywe izinhlansi namashaji kagesi.
Ukusetshenziswa kanye nezindlela zokuhlanganisa
I-Phenacetylene iyinhlanganisela yezinto eziphilayo. Yakhiwe indandatho ye-benzene exhunywe eqenjini le-acetylene (EtC≡CH).
I-Phenacetylene inezinhlobo eziningi zezicelo ku-organic synthesis. Nazi ezinye zezindlela eziyinhloko zokusetshenziswa:
Ukuhlanganiswa kwezibulala-zinambuzane: i-phenylacetylene iyingxenye ebalulekile yokuhlanganiswa kwezibulala-zinambuzane ezivame ukusetshenziswa, njenge-dichlor.
Izinhlelo zokusebenza zamehlo: I-Phenylacetylene ingasetshenziswa ekuphenduleni kwe-photopolymerization, njengokulungiswa kwezinto ze-photochromic, izinto ze-photoresistive, nezinto ze-photoluminescent.
Izindlela zokuhlanganiswa kwe-phenylacetylene kuma-laboratories nasezimbonini zimi kanje:
Ukusabela kwe-acetylene: ngokusabela kwe-arylation kanye nokusabela kwe-acetylenylation yeringi ye-benzene, iringi ye-benzene kanye neqembu le-acetylene kuxhunywe ukulungisa i-phenylacetylene.
Ukusabela kokuhlelwa kabusha kwe-Enol: I-enol eseringini ye-benzene isabela ne-acetylenol, futhi ukusabela kokuhlela kabusha kwenzeka ukukhiqiza i-phenylacetylene.
Ukusabela kwe-alkylation: indandatho ye-benzene ifakwa
