The present invention describes a chemically-assisted machining process that converts conventional lubricant chemistries to produce reactive oxygenated species that accelerate the formation of friction-reducing boundary layer lubrication during cutting operationstermed Ozonolytic Machining. The new type of cooling-lubricant chemistry is based on chemical reactions between unsaturated bio-based oils and alcohols, and other types of machining lubricants, containing carbon-carbon double or triple bonds, with ozone gas to form variously reacted or polymerized ozonidestermed super-oxygenated fluids, oils or alcohols, aldehydes or ketones, sulfurized ozonides and super-oxygenated gels.

The application relates to compositions comprising di-fatty-alkyl or -alkenyl polyalkylamines of the general formula (I) or (II), to a process for their preparation which involves a cyanoethylation step and a hydrogenation step, and their use as demulsifiers for oil-in-water emulsions, corrosion inhibitor, fuel additive, anti-scaling agent, asphalt additive, enhanced oil recovery agent for oil-wells, cutting-oil additive, and anti-static agent. The product show good performance combined with a favourable viscosity profile. ##STR00001##
