Ethynylbenzene, ris an canar cuideachd Phenylacetylene, (CAS: 536-74-3), cliog ceimigeachd, buidheann dìon feumail (Ph2P (O)) reagent airson terminal ethynes airson synthesis innealan dealanach.Eadar-mheadhanan air an cleachdadh gu cumanta airson synthesis neo-chunbhalach, agus ath-bheachdan synthesis organach a thathas a’ cleachdadh gu cumanta.Tha ethynylbenzene na hydrocarbon alkyne anns a bheil buidheann phenyl.faodar a chleachdadh anns na taobhan a leanas: 1, airson synthesis organach agus eadar-mheadhanan organach;2, air a chleachdadh mar eadar-mheadhanach cungaidh-leigheis.Tha Ethynylbenzene freagarrach airson a bhith a 'dèanamh synthesis de Alkynes Terminal le bhith ag ath-fhreagairt benzaldehyde ionadach le alcalan.Tha Ethynylbenzene, hydrocarbon cùbhraidh, cudromach anns a’ ghnìomhachas peitriceimiceach mar eadar-mheadhanach ann an cinneasachadh styrene, a tha e fhèin air a chleachdadh airson polystyrene a dhèanamh, stuth plastaig cumanta.Tha Ethynylbenzene an sàs ann a bhith ag ullachadh styrene le lùghdachadh a 'cleachdadh catalyst Lindlar.Bidh Ethynylbenzene a’ dol tro polymerization air a chatalachadh le iom-fhilltean Rh agus Pt gus polyphenylacetylene a chruthachadh.
