Lubricating oil additives, their preparation and use. |
摘要 |
<p>A lubricating oil soluble compound suitable for use as a dispersant additive is obtainable by reacting at elevated temperature an epoxyacrylate with a dispersant having at least one reactive nitrogen - containing moiety. Intermediates of the general formula IV <CHEM> where Y min is a group derived from the reaction of the epoxyacrylate with reactive nitrogen-containing moieties (ie primary or secondary amines) are novel. The process for preparing the lubricating oil soluble compounds can be a one step or multistep process. Lubricating oil compositions comprise a major proportion of lubricating oil and a minor proportion of the lubricating oil soluble compounds.</p> |
