In the present study, this is confirmed by the presence of bands for protons of CHOH groups (4.4 ppm) and protons of –CH2OH groups (3.8 ppm). The other side reactions like alcohol etherification with the epoxide groups or esterification with the acid groups are less likely to occur as indicated by a proportional loss of epoxide groups compared to the number of acid groups determined in similar syntheses |

The other side reactions like alcohol etherification with the epoxide groups or esterification with the acid groups are less likely to occur as indicated by a proportional loss of epoxide groups compared to the number of acid groups determined in similar syntheses 本研究中，4.4ppm处的CHOH基团质子峰及3.8ppm处的CH2OH基团的质子峰证实（该结果）。在类似的合成中检测到烷氧基与羧酸基团呈比例的消失证明其它副反应如醇与环氧的醚化、与酸的酯化发生的可能性极小。 |
