The storage method of bisphenol A synthesis catalyst is characterized by that the synthesized (dried or wet) catalyst can be placed in a container with good isolating property, for example in high-density polyethylene plastic barrel or aluminium-plastic composite bag and iron barrel, then the oxygen-removing agent can be added or the inert gases of nitrogen gas, argon gas and carbon dioxide can be used for substitution or the container is filled up with phenol, after the oxygen gas is removed, said container can be sealed and stored, so that the activity of said catalyst can be effectively retained.
