  The invention provides certain nicotine salts, co-crystals, and salt co-crystals and provides novel polymorphic forms of certain nicotine salts. In particular, nicotine salts with mucic acid, 3,5-dihydroxybenzoic acid, and 2,3-dihydroxybenzoic acid, and crystalline polymorphic forms of nicotine 4-acetamidobenzoate, nicotine gentisate, and nicotine 1-hydroxy-2-naphthoate are described. The invention further provides methods of preparation and characterization of such nicotine salts, co-crystals, and salt co-crystals and polymorphic forms thereof. In addition, tobacco products, including smoking articles, smokeless tobacco products, and electronic smoking articles comprising nicotine salts, co-crystals, and/or salt co-crystals are also provided.

  该发明提供了某些尼古丁盐、共晶和盐共晶，并提供了某些尼古丁盐的新颖多形态形式。具体来说，描述了与粘酸、3,5-二羟基苯甲酸和2,3-二羟基苯甲酸结合的尼古丁盐，以及尼古丁4-乙酰氨基苯甲酸、尼古丁吉替酸和尼古丁1-羟基-2-萘酸的结晶多形态形式。该发明还提供了制备和表征这些尼古丁盐、共晶和盐共晶以及其多形态形式的方法。此外，还提供了含有尼古丁盐、共晶和/或盐共晶的烟草制品，包括吸烟物品、无烟烟草制品和电子吸烟物品。
