Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, Non-U.S. Gov’t, Journal of Hazardous Materials called Efficiently capturing tobacco specific nitrosamines with Hβ zeolite in solution, Author is Shi, Chun Ling; Sun, Xiao Dan; Gao, Yi Han; Zheng, Sai Jing; Li, Shuo Hao; Yang, Jing; Wang, Yang Zhong; Xiong, Jun-Wei; Shen, Yi; Wang, Ying; Zhu, Jian Hua, which mentions a compound: 494-52-0, SMILESS is C1(C=NC=CC=1)[C@@H]1CCCCN1, Molecular C10H14N2, HPLC of Formula: 494-52-0.
The high-efficiency capture of Tobacco Specific Nitrosamines by Hβ zeolite in solution is reported for the 1st time, along with the adsorption of 4-methylnitrosamino-1-3-pyridyl-1-butanone in aqueous solution Different from other zeolites such as NaZSM-5, the specific pore size of Hβ exerted a crucial function endowing the zeolite a higher removal of TSNA and selectivity of NNK. The adsorption thermodn. of NNK by Hβ in aqueous adsorption was fitted to Temkin adsorption model with a linearly decreasing isosteric heat of adsorption. The adsorptive capacity of Hβ zeolite for NNK reached over 70 mg g-1, offering a powerful sorbent of TSNA to protect environment.
