As I explained in another thread, most modern organo-metallic AW and FM additives are liquids so as to be oil soluble:
Quote:
There are processes for preparing the organo-metal compounds which involves converting an alkali metal dihydrate of a Group VI metal; e.g., sodium metal dihydrate, to the corresponding metal acid hydrate of the Group VI metal. The metal acid hydrate is then reacted with an alkyl amine to form the organo-metal compound.
This can be done with Molybdenum, Titanium, Tungsten, Antimony, or just about any other metal.
