Seems a shame that there's only one recipe that uses yellow metal catalyst. From a gameplay perspective (rather than a chemistry perspective), one of the recipes unlocked by Nitrogen processing 4 could use it. On the route to Rocket fuel. Nitrogen dioxide > Dinotrogen tetroxide perhaps? It's a pretty boring recipe currently
Nitrogen processing 4 already depends on Advanced chemistry 4, which unlocks yellow metal catalyst.
