▎ 摘  要

NOVELTY - Synthesizing triazine ring from selfmade organic base catalyst using graphene as carrier comprises taking 2-methylthiosemicarbazide, diethyl oxalate, graphene-based self-made alkali catalyst, carrying out cyclization reaction using methanol at 0-60 degrees C to obtain triazine ring sodium salt, then separating the graphene carrier and decoloring, filtering, and acidifying to obtain triazine ring. USE - The method is useful for synthesizing triazine ring from selfmade organic base catalyst using graphene as carrier (claimed). ADVANTAGE - The method improves reaction product yield up to 85%, quality of the product, reduces viscosity of reaction system and production cost, and is easy to control.
