ABSTRACT:
The coacervation of ferrocene and ferrocene derivative is carried out in a ater-soluble polyol, coacervation mixture at a reaction temperature from about 40.degree. C. to about 55.degree. C. The coacervation mixture is comprised of about 70 to about 80 parts of a 1:1 ratio of water and a water soluble polyol selected from glycol, a glycerol, and an erythritol, a urea derivative selected from melamine and triazine, and an aldehyde or ketone selected from the water soluble aldehydes or ketones consisting of methanal, ethanal, propanal, propanone, and 2-butanone. Micro-droplets of the ferrocene derivative, 2,2-bis(ethylferrocenyl)propane, are formed by vigorous agitation of the coacervation mixture containing the ferrocene derivative. A polymeric coating on the outer surface of the micro-droplets produces a coacervate which is separated from the coacervation mixture. The coacervate polymeric coating of about 10 percent by weight enables the coated ferrocene derivative to be mixed in a solid propellant composition without rupturing and to achieve improved stability and compatibility as compared to liquid ferrocene and liquid ferrocene derivatives.
