采用红外光谱仪对动植物油脂加氢产物进行分析,分别读取2925,1745,1710 cm-1附近峰顶的校正吸光度,用波数1745 cm-1和2925 cm-1的校正吸光度之比作为酯烷比,用波数1710 cm-1和2925 cm-1的校正吸光度之比作为酸烷比,以此来监控加氢产物中的脂肪酸酯类、脂肪酸类等化合物的含量。结果表明:酯烷比和酸烷比可有效区分不同工艺条件的加氢深度并用于工艺条件的筛选研究。
採用紅外光譜儀對動植物油脂加氫產物進行分析,分彆讀取2925,1745,1710 cm-1附近峰頂的校正吸光度,用波數1745 cm-1和2925 cm-1的校正吸光度之比作為酯烷比,用波數1710 cm-1和2925 cm-1的校正吸光度之比作為痠烷比,以此來鑑控加氫產物中的脂肪痠酯類、脂肪痠類等化閤物的含量。結果錶明:酯烷比和痠烷比可有效區分不同工藝條件的加氫深度併用于工藝條件的篩選研究。

The products of hydrotreated animal fats or vegetable oils were analyzed by IR spectrome-ter. The corrected height of the peaks at 2 925,1 745,1 710 cm-1 were used to calculate A 1 745?A2 925 ,a ratio of ester to alkane and A 1 710?A2 925 ,a ratio of acid to alkane,which represent the contents of ester and acid in product,respectively. The results show that A 1 745?A2 925 and A 1 710?A2 925 are very effective to differentiate the hydrotreating depth,and can be used to screen the suitable reaction conditions for ani-mal fats or vegetable oils hydrotreating processes.
