Supported catalyst for preparing monocarboxylic anhydrides

摘要

In the supported catalyst for preparing monocarboxylic anhydrides by carbonylation of the corresponding esters or ethers, the support material (carrier material) supports a noble metal chelate formed from a noble metal compound of the 8th subgroup (transition group) of the periodic table of the elements and a chelator containing organonitrogen, organophosphorus, organoarsenic or organosulphur groups.
