Developing　new　NH3　separation　technology　is　very　meaningful　for　the　environmental　protection　related　to　ammonia　synthesis　process.　In　this　work,　we　found　that　ethylamine　chloride　(EaCl)　can　form　deep　eutectic　solvents　(DESs)　with　resorcinol　(Res)　and　phloroglucinol　(Phl).　The　chemical　and　physical　properties　of　new　DESs　were　determined　first,　because　they　are　the　basic　data　for　DESs.　Considering　that　such　kinds　of　DESs　have　multiple　weak　acid　sites,　we　systematically　investigated　the　NH3　absorption　performance　of　prepared　DESs.　We　found　that　the　prepared　DESs　show　chemical　absorption　for　NH3,　with　quite　high　NH3　solubilities,　particularly　at　reduced　pressures.　Specifically,　the　solubilities　of　NH3　in　prepared　DESs　reach　9.00　mol/kg　at　313.2　K　and　102.1　kPa,　and　3.73　mol/kg　at　313.2　K　and　4.7　kPa.　The　prepared　DESs　also　show　highly　reversible　absorption　for　NH3,　and　selective　absorption　towards　N2　and　H2.　The　underlying　mechanism　of　prepared　DESs　for　NH3　absorption　was　finally　investigated　by　theoretical　calculations　and　spectroscopic　characterizations.　©　2021　Elsevier　B.V.
