▎ 摘 要
NOVELTY - Preparing rubber antioxidant 2,2,4-Trimethyl-1,2-Dihydroquinoline polymer (TMQ) comprises using aniline and acetone as raw materials and a graphene oxide-based catalyst. USE - The method is useful for preparing rubber antioxidant (TMQ). ADVANTAGE - The rubber antioxidant: is easy to prepare; has a good catalytic effect; and avoids e.g. equipment corrosion, alkali neutralization and high cost of waste treatment.
