该实验室的部分研究计划需要合成一些环氧化合物。在该计划的后续行动中，需要合适的方法来检测这些不同的化合物。红外光谱法似乎是成功的最好方法。这涉及到化合物的红外吸收光谱的研究。本文记录了26种环氧化合物在2 ~ 15 μ m范围内的液态和溶液的红外吸收。确认了在约8微米处存在特征吸收带，并收集了在约11和12微米处存在另外两个特征吸收带的证据。后一条带的位置随化合物的不同而变化，范围为10.52（950 cm.-）1)至11.58微米（863厘米- 1)在11.0微米的位置和从11.57（864 cm.- 1)至12.72微米（786厘米- 1)在12微米的位置。谱带的波长位置与化合物与乙酸的反应活性之间存在一定的相关性。这一工作增加了对环氧化合物红外吸收光谱的认识。它还确定了在10- 13微米范围内存在环氧环的特征红外吸收带。因此，这方面的证据有限。谱带的波长位置和与乙酸的反应性之间的相关性具有相当大的理论意义和可能的实际应用。
Part of the research program of this laboratory required the syntheses of a number of epoxy compounds. In a follow-up of this program there was need for suitable methods for detecting these different compounds. Infrared spectroscopy appeared to offer the best hopes of success. This involved a study of the infrared ab-sorption spectra ofthe compounds. The infrared ab-sorption of 26 epoxy compounds were recorded from 2 to 15 microns, in the liquid state and in solution. The presence of a characteristic absorption band at about 8 microns was confirmed and evidence compiled for two other characteristic absorption bands at about 11 and 12 microns. The position of the latter bands varied with the compound, ranging from 10.52 (950 cm.-1) to 11.58 microns (863 cm.-1) in the 11.0-micron position and from 11.57 (864 cm.-1) to 12.72 microns (786 cm.-1) in the 12-micron position. Some correla-tion betweenthe wave-length position of the bands and the reactivity of the compounds with acetic acid was noted. This work adds to the knowledge of the infrared absorption spectra of epoxy compounds. It also establishes the existence of characteristic infrared ab-sorption bands for the epoxide ring in the 10-to 13-micron region. Heretofore, evidence of this had been limited. The correlation between the wave-length positions of the bands and the reactivities with acetic acid is of considerable theoretical interest and of pos-sible practical use.
