Comparison of the Synthesis Methods of AkarditeII and Introducing of the Optimal Method

In propellants, stabilizers are generally used to prevent their decomposition and so to increase their storage life. Among the stabilizers, N,N-diphenyl-N-methyl urea(AkarditeII) has special importance in military industries because, it is used to stabilize the double-based propellants. This importance has led to the study of the synthesis and optimization of the synthesis methods of AkarditeII. In this paper, at first, the properties and applications of AkarditeII are introduced and then different methods of the synthesis of the urea derivatives and AkarditeII are examined and compared. Finally, by considering the advantages and disadvantages of these methods and their potential to scaling up, the preferred method for preparation of AkarditeII is explained.
