Abstract
PURPOSE: To obtain the titled compound having a good hue useful as an additive for a hydrocarbon, by reacting an olefin with maleic anhydride in the presence of a small amount of an organic phosphite to suppress the formation of by-products and rise in reactor pressure.
CONSTITUTION: An olefin having an average molecular weight ≤50,000, preferably 70W5,000, and a double bond in the molecule is reacted with maleic anhydride in the presence of an organic phosphite, e.g. oleyl dihydrophosphite, trilauryl phosphite, or triphenyl phosphite in an amount of preferably 20W10,000ppm based on the total reaction system at 150W250°C to give the titled compound.
