Akardite II (AK-II, N-methyl-N′,N′-diphenylurea) is a well-known stabilizer for nitrocellulose (NC) propellants as it scavenges NOx. Currently, AK-II is produced using phosgene, a highly toxic gas. An alternative, two-step synthesis route is presented here that does not rely on phosgene. First, symmetrical organic carbonates (R2CO3, with R ​= ...
