| titleOfInvention |
Platinum catalyzed isomerization of alkenyl succinic anhydrides |
| abstract |
A process for preparing alkyl maleic anhydrides which comprises heating a lower alkenyl succinic anhydride in the presence of a catalytic amount of a platinum salt in combination with a weakly basic material under conditions effective to isomerize the alkenyl succinic anhydride. |
