Vorschrift

In another reaction vessel was placed 570 grams of the above isomerized eicosenyl succinic anhydride. This was heated to 160° C. and ammonia injection started. The temperature rose to 175° C. Ammonia injection was continued at 175° C. until the temperature dropped. Then 30" Hg vacuum was slowly applied to distill out water and ammonia. Additional ammonia was injected to be sure no anhydride remained. There was no further reaction so this ammonia was stripped out at 30" Hg vacuum at 170° C. yielding isomerized eicosenyl succinimide.
