【摘要】 本文用¹H—NMR谱测定了数种食用油,对峰面积积分进行了必要的整理以纠正CCH₂C最强峰对其两侧弱峰的干扰;并计算了油脂中每摩尔所含各功能团的个数、各功能团间的比率、酯化度、不饱和度、饱和碳链段平均长度、结合脂肪酸基平均碳数和平均分子量等。更多还原

【Abstract】 1H-NMR semi-quantitative determination of the edible oils was carried out with necessary adjustments of the partial peak integrations in order to correct the interference of the CCH2C strong peak to the neighbouring weak ones . The amount of each functional group, ratio of quantities among various functional groups, esterification degree, unsaturation degree, average length of the saturated carbon chain, average carbon numbers in the combined fatty acids and average molecular weight per mole of oils were calculated.更多还原
