摘要：
In a process for preparing a selectivated catalyst composition useful in the disproportionation of toluene, a catalyst comprising an acidic molecular sieve is contacted with a boron compound at a temperature in excess of 500° C.; and the resultant catalyst is then contacted with a medium containing hydrogen ions to at least partially restore the acid activity of the molecular sieve.
