NOVELTY - A Schiff base lead composite (I), is new. USE - New Schiff base lead composite used as combustion catalyst. ADVANTAGE - The compound (I) has good compatibility with modified double base propellant containing octogen and absorbent. DETAILED DESCRIPTION - A Schiff base lead composite of formula (I), is new. An INDEPENDENT CLAIM is included for preparation of compound (I) which involves placing graphene oxide ethanol dispersion in three-necked flask, adding N-aminoethyl- gamma -aminopropyltrimethoxysilane ethanol solution in drops, reacting under reflux for 2 hours, cooling to room temperature, centrifuging, washing with ethanol to obtain aminated graphene, placing the aminated graphene ethanol dispersion in a three-necked flask, adding salicylaldehyde ethanol solution in drops, reacting under reflux 3 hours, cooling to room temperature, centrifuging, washing with ethanol to obtain graphene-Schiff base complex, mixing graphene-Schiff base complex with lead nitrate aqueous solution, reacting at 50-60 degrees C for 4 hours, cooling to room temperature, centrifuging and washing with ethanol. The mass ratio of N-aminoethyl- gamma -aminopropyltrimethoxysilane to graphene oxide is 10-15:1. The mass ratio of salicylaldehyde to aminated graphene is 5-10:1. The mass ratio of graphene-Schiff base complex to lead nitrate is 0.5-1:1. The volume ratio of ethanol to water is 2-5:1.
