▎ 摘　　要

NOVELTY - The device has a reaction device which is connected in series with washing device, and comprised outer reaction container (6) and inner reaction container (8). Interlayer filling circulation control temperature medium layer (7) is formed between containers, and connected with external constant-temperature control tank (1). Discharge port formed in bottom of inner reaction container is penetrated through outer reaction container and connected with inlet of liquid storage tank (21) of washing device through pump machine (16). Storage tank is installed with stirrer (19). USE - Device for producing large diameter graphite oxide/ graphene oxide. ADVANTAGE - The convenient operation and stable performance of the graphite oxide/graphene oxide producing device are ensured. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the method for producing large size large diameter graphite oxide/graphene oxide. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the device for producing large diameter graphite oxide/ graphene oxide.
