Amino-alcs. are considered for sustainable hydrogen storage systems based on catalytic peptide formation. Exptl. and theor. thermochem. studies of amino-alcs. have been performed, including vapor pressure measurements, combustion calorimetry, and quantum-chem. calculations The standard molar enthalpies of vaporization of amino-alcs. were calculated from the temperature dependence of the vapor pressures measured by the transpiration method. Energies of combustion for six amino-alcs. were measured using the high-precision combustion calorimetry. The available in the literature primary data on vapor pressures, enthalpies of vaporization, and enthalpies of formation of amino-alcs. were collected and evaluated. The exptl. standard molar gas-phase enthalpies of formation of amino-alcs. were derived from the evaluated results. The high-level G3B3, G3MP2, and G4 quantum-chem. methods were used to establish consistency of the exptl. and theor. results. The surprisingly low enthalpy of reaction of the reversible dehydrogenation of 2-amino-ethanol, calculated from the exptl. data, makes this liquid organic hydrogen carrier system (LOHC) promising for further optimization and development. This study involved multiple reactions and reactants, such as 2-Methoxyethylamine (cas: 109-85-3Application of 109-85-3).
2-Methoxyethylamine (cas: 109-85-3) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Application of 109-85-3
