ABSTRACT:
Functional fluids such as metal working fluids are disclosed which include an oil of lubricating viscosity, a sulfurized organic compound, and an amine derivative. The amine derivative is a hindered imine which is the reaction product obtained from reacting a primary amine connected to a tertiary alkyl group with an aldehyde or aldehyde reaction synthon. The inclusion of the hindered imine within the metal working fluid suppresses the generation of hydrogen sulfide gases during the use of the fluid thus improving the environmental and safety characteristics of the fluid.
