Abstract:
Provided are an organic electrolyte and a redox flow battery comprising the same. By using an electrolyte having excellent solubility which is stable to moisture and heat, a battery with high energy density can be provided. An organic electrolyte according to an embodiment comprises a metal-ligand coordinate compound whereby the ligand is an organic phosphate compound. The organic phosphate compound is trimethyl phosphate, triethyl phosphate, tripropyl phosphate, or triphenyl phosphate. [Reference numerals] (AA) Voltage [V]; (BB) Capacity [mAh]
Abstract:
The present invention relates to a method for synthesizing 11-aminoundecanoic acid being a polyamide-11 monomer derived from a natural material and, in particular, to a method for synthesizing 11-aminoundecanoic acid or an ester derivative thereof being a material for polyamide-based thermoplastic elastomer (TPE) from oleic acid or an ester derivative thereof obtainable from olive oil being a natural material. The present invention provides the novel eco-friendly and efficient method for synthesizing 11-aminoundecanoic acid because the 11-aminoundecanoic acid synthesized according to the present invention can be used as a monomer for polyamide-11, and can be synthesized from oleic acid or an ester derivative thereof obtainable from naturally derived olive oil.
