Polymorphism in acesulfame sweetener: structure-property and stability relationships of bending and brittle crystals

摘要

Acesulfame is found to exist in two crystalline forms of which Form Ⅰ (needles) shows bending upon mechanical stress. Crystal structures explain their mechanical response. This is the first case of aliphatic organic compounds featuring a bending phenomenon. Form Ⅰ is physically more stable than Form Ⅱ in ambient conditions.
