| 摘 要： | 以环戊基甲基酮和水合肼为原料，合成一种新的酮连氮化合物（环戊基甲基酮连氮，C14N2H24），采用1H NMR、13C NMR和IR表征确认产物的结构，并通过Gaussian 09计算对产物分子构型进行解析，表明（1E，2E）为最稳定构型；同时测定环戊基甲基酮连氮在常压下的基本物理化学性质，包括沸点（Tb，238.4℃）、熔点（Tm，-38.2℃）、密度（ρ，0.910~0.969 g·cm-3）、动态黏度（η，2.35~13.17 mPa·s）和比热容（Cp，2.97~3.63 J·g-1·℃-1），并根据密度计算其等压热膨胀系数（α，8.26×10-4~8.75×10-4℃-1）。结果显示ρ、η与温度呈负相关，Cp、α与温度呈正相关。

| Abstract: | In this paper, a new ketazine compound (C14N2H24) was synthesized from cyclopentyl methyl ketone and hydrazine hydrate. After the separation and purification of the product, the structure of cyclopentyl methyl ketazinewas determined by 1H NMR,13C NMR, and IR spectra. With Gaussian 09 computation, the structure (1E, 2E) of the product was proved to be the most stable molecular configuration. Furthermore, the basic physical and chemical properties of cyclopentyl methyl ketazine under atmospheric pressure were measured, including boiling point (Tb, 238.4℃), melting point (Tm, -38.2℃), density (ρ, 0.910-0.969 g·cm-3), dynamic viscosity (η,2.35-13.17 mPa·s), and specific heat capacity (Cp, 2.97-3.63 J·g-1·℃-1). The thermal expansion coefficient (α, 8.26×10-4-8.75×10-4℃-1) was calculated according to its density.The results show that ρ and η have a positive correlation with temperature while Cp and α have a negative correlation with temperature. The obtained data and correlation formula are very valuable for the industrial application of cyclopentyl methyl ketazine. |
