This trend is in agreement with the hydrodynamic diameter measurement and could provide some indirect information about the coverage density of —S-PEG-NH 2 chains on AuNCs, as well as the polymer chain conformation. During ligand exchange, HS-PEG-NH 2 could displace the original capping ligand on the surface of a Au nanostructure thanks to a relatively strong Au-S bond and the energy gained through intermolecular interactions between the PEG chains. It was in the form of fine dry particles. Furthermore, the removal of amine in this case was somewhat better than in the case of 2-methyl phenol of Example 4. As shown in Table 1the ninhydrin-based assay was found to consistently give a larger number of PEG chains per AuNC as compared to the fluorescamine-based assay. In a preferred embodiment the excess of aminating compound is recycled for reuse in the process. In particular, ethylene diamine EDA is used as a raw material for the preparation of a number of chemicals such as chelating agents, fungicides, and synthetic resins like fibres.

The quantity of desorbed methylamine relative to the adsorbed quantity shows full recovery of the adsorbed methylamine.
Process for the hydrogenation of hydrocarbon oils and kerosene feedstock, cycle oils or hydrocracking product whenever obtained by the same. In a basic solution, the primary amine was deprotonated and thus became highly reactive toward fluorescamine.
USA1 en. In yet another embodiment, it was found that methylamine and ethylamine can be suitably removed by a distillation step, as they have a different boiling point from the boiling points of the other components present in the reaction streams.
