Abstract
Abstract Stable water-in-oil invert emulsions suitable for use as fire-resistant lubricants and as fire-resistant hydraulic fluids of improved extreme pressure (E.P.) properties are disclosed. A mixture of polyisobutenyl succinic anhydride, a member selected from the group consisting of a vegetable or animal oil or a mixture thereof, and a mono alpha-unsaturated olefin is sulfurized under heat. The sulfurized mixture is then reacted with a hydrophile on an equivalent basis. This compound is then blended with suitable base stock to form an invert emulsion with improved E.P. and anti-wear properties.
