The metallic soaps of naphthenic acids — Part 6 Available to Purchase

Manganese naphthenate has been utilized to improve the combustion properties of kerosine and to reduce soot content of flue gases. It is also applicable as a corrosion inhibitor in gas turbine engines using naphtha as a fuel, and can be added to fuel of these engines to minimise corrosion at high temperature and filter blocking tendency, and to modify the type of deposit formed on turbine blades so that it is less adherent and softer, especially when cyclopentadienyl manganese tricarbonyl is used as a smoke reducer. The manganese naphthenate soap has been utilized to inhibit wear in low speed marine diesel engines operating on vanadium‐containing residual‐type fuel oils, and it can be employed to reduce the ignition temperature of soot in furnaces, by as much as 200%, facilitating oxidative soot removal from, especially, oil‐fired furnaces. The addition of the product to heavy tractor oil can reduce sulpher trioxide concentration. Manganese naphthenate has been used as a catalyst to the manufacture of organo‐boran compounds for use in petrol and lubricants.
