英文摘要:

      Objective To study the molecular structure of sucralose and its intermediates. Methods The sucrose-6-ester, sucralose-6-ester and sucralose were scanned by the infrared spectrometry (IR) and analyzed by the mass spectrometry (MS). Results The molecular ion, fragment ion and the functional groups of sucralose and its intermediates were identified. Conclusion The molecular structure of sucralose, sucrose-6-ester and sucralose-6-ester were successfully analyzed.
