Abstract: A method for preparing bio adipic acid includes steps of (a) preparing a glucaric acid potassium salt by mixing and reacting glucose, nitric acid (HNO3), sodium nitrite (NaNO2) and potassium hydroxide (KOH), (b) preparing glucamide from the glucaric acid potassium salt prepared in the step (a), (c) preparing 2,4-hexadiene diamide by performing a deoxydehydration reaction on the glucamide prepared in the step (b), (d) preparing adipamide by introducing the 2,4-hexadiene diamide prepared in the step (c), hydrogen and a hydrogenation catalyst to a reactor and performing a hydrogenation reaction, and (e) preparing adipic acid by introducing the adipamide prepared in the step (d) and an aqueous hydrochloric acid solution to a reactor and then performing a hydrolysis reaction at a specific temperature.

Abstract: The present disclosure herein relates to a terminally-crosslinked methyl morpholinium-functionalized block copolymer, and an anion exchange membrane using the same, and more particularly, to a terminally-crosslinked block copolymer which has a novel structure, and in which, in a poly(arylene ether sulfone) multiblock copolymer (MM-PES) having methyl morpholinium as a conducting group, an azide compound may be used as a crosslinking agent so that crosslinking only occurs at ends of the polymer chains (xMM-PES), thereby minimizing conductivity loss, significantly increasing mechanical and chemical stability, attaining additional conductivity resulting from the three-dimensional structure of morpholinium, and reducing water uptake while enhancing water retention capacity, uses thereof as an alkaline fuel cell anion exchange membrane (AEM), and a method for conveniently preparing the same through simple heat-treatment.
