应用阿贝折射仪测定了薄荷醇与乙醇、甲醇构成的两组分溶液的折光率,利用SPSS统计软件对实验数据进行线性相关和回归处理,结果表明组成与折光率之间呈线性关系,其相关系数均在0.99以上,且实验值与文献值相符,该方法完全适合用于薄荷醇溶液在常温下组成的测定。 Abbe refractometer was used to measure the refractive index of the two components of menthol with ethanol and methanol. SPSS statistical software was used to conduct linear correlation and regression analysis of the experimental data. The results showed that there was a linear relationship between the composition and refractive index The correlation coefficients are above 0.99, and the experimental values ​​are consistent with the literature values. This method is perfectly suitable for the determination of the composition of menthol in normal temperature.
