Disclosed are succinimide-based compounds used in compositions and methods for inhibiting natural gas hydrate agglomerates. The succinimide-based compounds are reaction products of an alkenyl succinic anhydride and an amine or amine alcohol.

The flame-retardants of this invention were formed by the direct reaction of ethyleneamines and commercial polyphosphoric acid at an elevated temperature. It was unexpected that a high temperature had to be used to overcome reaction barrier to formation. These compounds are found to be efficient flame retardants.
