METHOD OF PREPARING IMPROVED CATALYST FOR PRODUCTION OF ACRYLIC ACID

摘要

The present invention provides a method of preparing an oxide catalyst for the production of acrylic acid by preparing a catalyst precursor from the solution mixture of molybdenum salt, vanadium salt, tellurium salt and niobium salt and drying and firing thereof. The present invention is characterized by the addition of acid complex mixture comprising carboxylic acid, peroxide and sulfuric acid compounds as an additive to obtain the catalyst precursor. According to the method of the invention, the oxide catalyst for the production of acrylic acid having excellent catalytic activity can be prepared.
