摘要:本文围绕新型保鲜剂-1-甲基-3-(2-甲基环丙基)-1-环丙烯包合物(1-MMCPCP/M-β-CD,M-β-CD中的M代表Cu2+、Ni2+、Fe3+、Fe2+、Ag+和Mn2+六种金属离子)的绿色合成、包合机理、合成条件的优化及其应用效果进行实验研究与分析,主要做了以下工作: 分别以六种金属离子(Cu2+、Ni2+、Fe3+、Fe2+、Ag+和Mn2+)作为催化剂,催化1-甲基环丙烯(1-MCP)合成1-甲基-3-(2-甲基环丙基)-1-环丙烯(1-MMCPCP),并以β-环糊精(β-CD)为载体,将1-MMCPCP固定于其空腔中,成功合成了1-MMCPCP/M-β-CD固体粉末。经过气相色谱-质谱联用分析技术(GC-MS)和释放曲线的测试,结果表明,六种金属离子均可催化1-MCP形成1-MMCPCP,并固定在M-β-CD中形成1-MMCPCP/M-β-CD包合物粉末。通过傅里叶转换红外光谱分析(FT-IR)、X射线粉末衍射分析(XRD)以及固态核磁分析(SSNMR)等表征手法分析,结果表明所合成的1-MMCPCP/M-β-CD包合物中的1-MMCPCP、M-β-CD两类物质形成了新的物象,并非是简单的物理混合。

The Research on Green Synthesis of 1-methyl-3-(2-methylcyclopropyl)-1-cyclopropene inclusion compounds
Abstract:In this paper, focused on the green synthesis method, inclusion mechanism, the optimization of synthesis condition and the application effects for the inclusion compound of 1-methyl-3-(2-methylcyclopropyl)-1-cyclopropene/M-β-cyclodextrin (1-MMCPCP/M-β-CD, the M in M-β-CD represented. The Research on Green Synthesis of 1-methyl-3-(2-methylcyclopropyl)-1-cyclopropene inclusion compounds Cu2+, Ni2+, Fe3+, Fe2+, Ag+ and Mn2+) were analyzed. The primary research contents are shown as follows: Using six metal ions (Cu2+, Ni2+, Fe3+, Fe2+, Ag+ and Mn2+) as catalysts separately, the catalytic synthesis of 1-methyl-3-(2-methylcyclopropyl)-1-cyclopropene (1-MMCPCP) solid powder with 1-methylcyclopropene (1-MCP) was successfully accomplished. During this synthesis process, β-cyclodextrin (β-CD) was applied as the carrier, for the fixation of 1-MMCPCP. With gas chromatography-mass spectrometry analysis technique (GC-MS), the test results of the release curve showed that the six metal ions had effects on the catalytic synthesis of 1-MMCPCP solid powder with 1-MCP, and indicated that 1-MMCPCP was fixed in the cavity of M-β-cyclodextrin (M-β-CD) by forming the 1-MMCPCP/M-β-CD inclusion compound powder. The structure and component of this inclusion compound was characterized by fourier transform infrared spectrometer(FT-IR), X-ray diffraction(XRD), and solid-state nuclear magnetic resonance(SSNMR). The results indicated that the inclusion compound of 1-MMCPCP/M-β-CD was a brand new compound rather than the simple physical mixture of 1-MMCPCP and the inclusion complex of M-β-CD.
