“…S34), demonstrating the dehydration effect of the GO/GONR interlayer. We note that the newly-appeared peak at ~1450 cm -1 in our FTIR analysis was due to the H-O-D bending, which was a consequence of the mixing of H 2 O and D 2 O in the feed side [42] . In comparison, the solution in the permeat side was composed of pure H 2 O, and only a negligible amount of D 2 O was found to diffuse across the GO/GONR membrane throughout the test.…”

“…Various compounds, such as carboxylic acids, aromatic compounds, and ionic liquids can be effectively deuterated using platinum group metalcatalyzed direct deuterium-labelling methods [8][9][10][11][12]. In contrast, even though amines are important functional molecules, there is no effective direct multi-deuteration method for amine compounds.…”

In neutron scattering studies, deuterium-labelled compounds play a key role in controlling the contrast of organic samples and reducing the incoherent scattering background from the samples. As amine compounds play a vital role as functional molecules, we have developed a new synthesis method using an amide compound as a starting material to synthesize deuterated amines and their analogues. We determined the deuteration ratio of the obtained deuterated 1-octylamine by mass spectrometry, nuclear magnetic resonance (NMR), and neutron reflectometry techniques. As a result, the deuteration ratio was estimated to be ~60 %. The deuteration ratio of the synthesized 1-octylamine was not high because the method used did not deuterate its α-protons and NH2 group. However, this synthesis method is suitable for the large-scale synthesis of deuterated amine compounds for neutron research because it is easy to increase the synthetic scale.
