凹土-电气石复合材料制备及对白酒酯类合成的影响
|
摘要
试验探讨了凹土与电气石复合材料制备及对白酒酯类成分的影响。首先,将凹土与电气石按不同质量比混合,450℃下煅烧4.5 h,得到3组凹土-电气石复合物。其次,采用傅里叶变换红外光谱、扫描电子显微镜和热重-差热分析法研究凹土、电气石及其复合材料的晶体性质及热力学特性。研究表明,与天然凹土或电气石相比,制备的复合材料(PT-5)具有粗糙而多孔的表面结构。最后,采用气相色谱法对酒样中酯类物质进行定量分析,并以陶粒为对照,考察凹土、电气石及其复合物对酒中酯类物质合成催化效果,发现凹土-电气石复合物对白酒酯类含量的影响显著,并随着储存期延长,乙酸乙酯、丁酸乙酯、己酸乙酯生成量显著提高,当凹土与电气石的混合质量比为4︰1时,制备的凹土-电气石复合物(PT-5)更有助于白酒酯类成分(乙酸乙酯、丁酸乙酯、己酸乙酯)的生成。PT-5的酯类催化合成效果可能与它表面的多孔结构以及引入的电气石催化活性有关。
In the present study, palygorskite-tourmaline composites were prepared and their enhanced effects for esters content in Chinese liquor were studied. The palygorskite and tourmaline were mixed in different ratios and clacined at 450 ℃, resulting in three calcined palygorskite products. The interaction between palygorskite and tourmaline in the composites was investigated and characterized using Fourier transform infraredspectroscopy(FTIR), scanning electron microscopy(SEM) and thermogravimetric-differential scanning calorimetry(TG-DSC) analysis methods. When dispersed in Chinese liquor sample, all composites showed signifi cantly enhanced esters contentin Chinese liquor in comparison of natural palygorskite. The palygorskite-tourmaline composite(PT-5) with the ratio of palygorskite to tourmaline was 4︰1 showed the highest ability to increase esters content in Chinese liquor. The increased effect of PT-5 on esters content in Chinese liquor might be related to its surface porous structures.
