A study on the reaction pathway for isomerization of tetrahydrotricyclopentadiene using ionic liquid catalyst was written by Kim, Dae Hyun;Han, Jeong-Sik;Jeon, Jong-Ki;Yim, Jin-Heong. And the article was included in Kongop Hwahak in 2015.Safety of Pyridinehydrochloride This article mentions the following:
The kinetic behavior of tetrahydrotricyclopentadiene (THTCPD) isomerization was studied by using two kinds of chloroaluminate ionic liquid (IL) catalyst with different Lewis acidity. THTCPD isomerization pathway was discussed under the different temperature and time as reaction parameters using IL catalysts consisting of 1-butyl-3-methylimidazolun chloride (BMIC)/AlCl3 with low acidity and pyridine hydrochloride (PHC)/AlCl3 with high acidity. The conversion of THTCPD isomerization increased with increasing Lewis acidity of IL catalyst. The THTCPD isomerization pathway changed as a function of reaction temperature and catalyst acidity. In the case of BMIC/AlCl3 IL catalyst, THTCPD isomerization pathway was similar to that of using conventional AlCl3 catalyst. However, two different types of addnl. pathways (endo, exo, endo-NB 閳?exo, exo, endo-NB 閳?exo, exo, exo-NB and endo, exo, endo-NB 閳?exo, exo, endo-NB 閳?exo, exo, exo- CP) were appeared when using PHC/AlCl3 IL catalyst. In the experiment, the researchers used many compounds, for example, Pyridinehydrochloride (cas: 628-13-7Safety of Pyridinehydrochloride).
Pyridinehydrochloride (cas: 628-13-7) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Safety of Pyridinehydrochloride
