【摘要】 对氨基硅油柔软剂,采用溶剂提取、柱层析、碘代等方法进行预处理,以红外光谱、凝胶色谱、裂解色谱、质谱、气质联用和化学降解法对各组分进行定性检测及结构鉴定,采用重量法对各组分进行定量分析。更多还原

【Abstract】 Solvent extraction and silica gel column chromatography were used to separate components in amino silicone softeners with unknown compositions,respectively.FTIR,GPC,PY-GC/MS,ESI/MS and deposing methods were used to determine the structures of separated components.Preliminary quantitative analysis was carried out.The contents of every composition are determined by weight method.更多还原
