摘要：

采用溶液包合法利用α-环糊精（α-CD）对1-甲基环丙烯（1-MCP）进行包合，将气态的1-MCP固态化形成白色粉末状的1-MCP/α-CD稳定包合物，使之便于保存和应用。利用拉曼光谱（Raman）、X-射线粉末衍射光谱（XRD）、气质联用测试（GC-MS）、核磁谱仪（NMR）等测试技术对所得包合物的结构和组成进行表征，证明了包合物的形成，同时提出了1-MCP/α-CD包合物中1-MCP含量的快速测定方法，以该法测定的包合物中1-MCP的有效含量约为3.6%。对1-MCP和α-CD的包合机理进行了探讨，认为1-MCP和α-CD按摩尔比1:1进行包合。

Abstract:

The experiment was conducted to investigate how to better preserve and apply 1-MCP. In this study, The inclusion complex of 1-methylcyclopropene (1-MCP) and α-cyclodextrin (α-CD) was synthesized by inletting 1-MCP gas into the α-cyclodextrin saturated solution.Raman spectroscopy，X-ray powder diffraction (XRD), Gas Chromatography/ Mass Spectrometry(GC-MS) and Nuclear Magnetic Resonance Spectrometer(NMR) analysis methods were used to verify the existence of 1-MCP/α-CD inclusion complex. A rapid determination method was proposed for measuring the content of the 1-MCP in the inclusion complexes,which was about 3.6wt%. Moreover, the formation mechanism of the inclusion complex was also discussed. And the inclusion ratio was suggested a 1:1 ratio of 1-MCP and α-CD complexation.

Key words: methylcyclopropene, a-cyclodextrin, inclusion complex
