ABSTRACT:
A cobalt based catalyst, and the method for preparing it, are disclosed. The catalyst is obtained from the reaction between NaCo(CO).sub.4 and s-trichloro triazine and is advantageously used in the processes of carbonylation of naphthalene mono- and disulfonates in order to yield naphthalene esters and acids.
