PROCESS FOR PREPARING POLYALKENYL SUBSTITUTED MONO- AND DICARBOXYLIC ACID PRODUCING MATERIALS

A low-sediment, low-tar, chlorine-free thermal process for preparing oil-soluble polyalkenyl derivatives of monounsaturated C3-C10 monocarboxylic acid producing compounds and monounsaturated C4-C10 dicarboxylic acid producing compounds is disclosed. The process involves reacting the mono- or dicarbo...

Beschreibung
Zusammenfassung:	A low-sediment, low-tar, chlorine-free thermal process for preparing oil-soluble polyalkenyl derivatives of monounsaturated C3-C10 monocarboxylic acid producing compounds and monounsaturated C4-C10 dicarboxylic acid producing compounds is disclosed. The process involves reacting the mono- or dicarboxylic acid producing compound with a polyalkene at high temperature and under high inert gas partial pressure in the presence of a sediment-inhibiti ng amount of hydrocarbyl substituted sulfonic acid. The polyalkenyl derivatives are useful per se as additives in lubricating oils, functional fluid s, and fuels and are also useful as intermediates in the preparation of other products (e.g., succinimides) useful as additives in lubricating oils, functiona l fluids, and fuels.
