【摘要】 碳炔是碳的同素异形体,利用聚偏氯乙烯和乙醇钠的均相脱HCl反应制备碳炔,并用原位红外测量装置研究了碳炔的热稳定性。结果表明,碳炔在室温下比较稳定,随温度升高稳定性快速降低,高于220℃后碳炔结构已基本消失。更多还原

【Abstract】 Carbyne is a new carbon allotropes based on sp hybridization that contains alternating triple and single bonds(linear carbon allotropes).Carbyne was synthesized with homogeneous dehydro-chlorination of PVDC.Thermal stability of carbyne was studied by self-manufacture instantaneous-measure device.The result shows that carbyne is stabile at room temperature and carbyniod structure is disappeared when the temperature is higher than 220℃.更多还原
