Abstract
Ru/C-catalyzed hydrogenation of m-xylylene diamine into 1,3-cyclohexanebis(methylamine) was greatly accelerated by the presence of LiNO3, NaNO2, or NaNO3. It was found that the effect of the nitrate salt was significantly affected by the size of cation. The promoting effect of the nitrate salt increased with the decrease of the cation size: LiNO3 ~ NaNO3 > KNO3 > CsNO3 >> [1-butyl-3-methylimidazolium]NO3. XRD analysis of the recovered catalysts after the hydrogenation reactions showed that LiNO3 and NaNO3 were completely transformed into LiOH and NaOH, respectively, along with the evolution of NH3, while KNO3 and CsNO3 remained unchanged.
