已发现Br（CH 2）nN（CH 3）2型胺在n为4、5和6的情况下发生分子内反应生成环状季铵盐。1以前，Knoor和Roth 2研究了当-氯丙基二甲胺（I）在水溶液中溶解时形成的产物，并将由此得到的季铵盐指定为八元环结构（II）。
Amines of the type Br (CH2)„N (CH3) 2 havebeen found to react intra-molecularly to produce cyclic quaternary ammonium salts in those cases where n has the value 4, 5 and 6.1 Previously, Knoor and Roth2 had studied the product formed when-chloropropyldimethylamine (I) was allowed to polymerize in aqueous solution and had assigned an eight-membered ring structure(II) to thequaternary ammonium salt thus obtained.
