Definitions
- a lubricating oil composition which comprises a major amount of lubricating oil and a minor amount of an extreme pressure property improving additive which is a compound having the formula where R is hydrogen, alkyl of 1 to 4 carbon atoms or chlorine, R" is hydrogen or chlorine, R is hydrogen or methyl and x is a number from 1 to 10, usually not over 6 and normally 1 to 3.
- the additive is made by reacting styrene or the appropriate substituted styrene with a sulfurizing agent such as sulfur monochloride or a dichlorosulfane, e.g., sulfur dichloride.
- styrene or a substituted styrene is reacted with sulfur monochloride or a dichlorosulfane, e.g., sulfur dichloride at to C with or without a solvent inert to both reactants.
- the reaction is allowed to proceed to completion over a period of 3 to 5 hours.
- the product can then be washed with a small amount of alkali to neutrality or alternately blown with air to remove any retained hydrogen chloride.
- the product obtained can be used in combination with a lubricating oil as a high temperature lubricant and as an extreme pressure lubricant.
- bis(B-chloro-B-phenyl ethyl )disulfide and its derivative are typically ASTM Dl500-color l-3 C -CH S where R is hydrogen, alkyl of l to 4 carbon atoms or chlorine, R" is hydrogen or chlorine, R is hydrogen or methyl and is a number from 1 to l0.
