CATALYST RESINS AND PROCESS FOR THEIR PREPARATION

摘要

The invention relates to a new process for the preparation of strongly acid cation exchangers loaded with catalytically active metals by loading the cation exchangers with a solution of a salt of the catalytically active metal and reducing the cation exchangers loaded with metal ions, according to which the loading of the cation exchangers is carried out at temperatures from 50 DEG to 120 DEG C. and formic acid is used as the reducing agent; the invention also relates to the catalyst resins which can be obtained by the process.
