| 摘 要： | 针对产自我国某地的一种具有天然奶油巧克力香味的香石(玉),利用常规化学分析、红外光谱分析及X射线衍射分析方法,确定了此种香石(玉)的矿物归属.并用固相微萃取-气相色谱-质谱联用分析技术分析香石(玉)的挥发性气体成份,结果表明:香石(玉)的化学成份w(B)/%为SiO2 49.02;MgO 43.51;Al2O3 0.48;CaO2.01;Fe2O3 1.41;H2O+11.00.红外光谱具有蛇纹石红外光谱特征,X射线粉末数据亦与蛇纹石吻合,其矿物种属确定为蛇纹石.香石(玉)的挥发成份中有67种有机组分,经鉴定含有18种具有香味的有机化合物,香味成分约占挥发性成分总量的55%左右.蛇纹石是一种层状硅酸盐矿物,呈卷曲的园柱管状结构,这种特殊结构决定了它具有吸附能力,在地质构造运动产生的特殊温度、压力环境下,被吸附的有机物熟化使蛇纹石产生如奶油巧克力的特殊香味.
