AI Technical Summary

Benefits of technology

This patented new type material called Ferrocene (CAS No.: 98941-5) was developed by researchers at Los Alamos National Laboratory during World War II with excellent properties such as heat resistance, chemical reactivity, and ability to absorb light from sunlight without losing any part or affecting their effectiveness when exposed to certain substances like hydrocarbons. These materials are useful because they have strong interactions that allow them to participate effectively within various systems where there may exist harmful agents. They could potentially replace existing regulators made up entirely of ferrocenes due to these advantages over other methods.

Problems solved by technology

This patented technical solution described for improving the stability and durable performance of ferrccenes and related substances in different types of ammunition materials involves introducing specific chemical moieties like oxygen or nitroxides onto them through experiments with varying degrees of success. However, there still exist issues associated with this approach due to potential migrations, vapor pressure reduction, slow crystal formation, poor solubility, and limited ignitabilities caused by conventional techniques.

Abstract

The invention relates to a ferrocene high-nitrogen ionic compound and a preparation method thereof. The structural formula of the compound is disclosed as Formula (1), wherein X is C or N; R is C[m]H[2m+1], and m is 1-16; and Y<-> is N[3]<-> or [N(NO[2])[n](CN)[2-n]]<-> (n is 0-2), or [C(NO[2])[n](CN)[3-n]]<-> (n is 0-3), or high-nitrogen heterocyclic anion or polynitrophenol anion or di-tetrazole anion. Since anions and cations have Coulomb electrostatic interaction, the ferrocene high-nitrogen ionic compound has the advantages of high heat stability and high catalytic performance, and can be used as a catalyst in a rocket propellant; the ferrocene high-nitrogen ionic compound has low steam pressure and is nonvolatile under natural conditions, and therefore, can solve the problems of high migration tendency and high volatility of the existing ferrocene combustion regulator in the propellant; and meanwhile, the synthesis method is simple and easy to implement, has the advantage of low cost, and is applicable to industrialized application.
