高纯硅溶胶中未知杂质成分分析

摘要

为提升高纯硅溶胶产品品质，采用有机元素分析、红外光谱、气相色谱-质谱联用技术（GC-MS）对高纯硅溶胶中未知杂质成分进行分析。通过有机元素分析确定高纯硅溶胶中包含有机物杂质，采用红外光谱对高纯硅溶胶中未知化学成分进行综合定性与解析，综合GC-MS总离子流图与谱库检索结果，进一步确定高纯硅溶胶中未知杂质成分为松油醇。对松油醇杂质的来源进行分析和讨论，有助于高纯硅溶胶生产工艺与产品质量提升。%To improve the quality of high-purity silicasol, the chemical components of the unknown impurities in high-purity silicasol were analyzed synthetically through elemental analysis, ATR-FTIR and GC-MS. The results of elemental analysis reflected there was organic foreign matter contained in the high-purity silicasol. The comprehensive results of ATR-IR demonstrated that the impurity in the high-purity silicasol was terpineol. The total ion chromatogram and the analytical results of the chemical constitutions of GC-MS confirmed the results of ATR-IR furtherly that the unknown impurity was terpineol. The source of terpineol was analyzed and this work is beneficial for both the improvement of the production technology and the quality of high-purity silicasol.
