Abstract: 以巴伦亚烯为原料合成了圆柚酮,并对其晶体结构进行了分析鉴定.该化合物属于单斜晶系,空间群为P21,晶胞参数a=0.590 3(2) nm,b=0.949 5(4) nm,c=1.163 0(6) nm,β=96.09(2)°,V=0.648 2(5) nm3,晶体计算密度Dx=1.119 mg·m-3,Z=2,μ=0.07 mm-1.将圆柚酮用作烟用香料的使用结果表明:在温度为20 ℃时,该化合物的香气阈值为0.001 mg·L-1;在卷烟中使用具有增加卷烟香气,丰满卷烟香味和降低刺激的作用;作为烟用香料使用,圆柚酮在烟丝中的最适宜添加量为w(圆柚酮)=(1~10)×10-6.
