摘　　要：总结和归属了α呋喃丙烯酸酯红外光谱的主要特征．１．呋喃环３个特征吸收谱带如下：①环Ｃ—Ｈ和骨架伸缩振动频率分别为３１３０和１５６０、１４８０、１３９１ｃｍ－１；②环中Ｃ—Ｏ—Ｃ键对称和不对称伸缩振动频率分别为１０７５和１２１０ｃｍ－１；③环Ｃ—Ｈ面外弯曲振动和环弯曲振动频率分别为８８５和７５０ｃｍ－１．２．Ｃ＝Ｃ键伸缩振动频率为１６４１ｃｍ－１；在９７３ｃｍ－１显示反式＝Ｃ—Ｈ面外变角振动的特征频率．３．羰基伸缩振动频率为１７１３ｃｍ－１，１３０５，１２６２和１１６５ｃｍ－１为α。The IR spectra of alkyl α furanacrylates was characterized by the followwing aspects: 1. There were main characteristics for α furan ring, and its ring vibration frequencies were near 1560,1480, and 139cm -1 , respectively, while the frequency of ring C H was 3130cm -1 . The asymmetric and symmetric stretching vibration frequencies of C O C in the ring were 1075 and 1210cm -1 , respectively. The vibration frequencies of the external plane of C H ring and that of the bending vibration were 885 and 750cm -1 , respectively. 2. The sharp and strong absorption peaks for C=C stretching mode and the out of plane of =C H bending mode were 1641 and 937 cm -1 , respectively. The stretching vibration frequency of carbony group was 1713 cm -1 , and the three strong absorption peaks for symmetric and asymmetric C O C band in α,β unsaturated ester were 1305, 1262 and 1165 cm -1 , respectively.
