Fuel lubricity additives

摘要

A fuel lubricity additive compound which comprises an intermediate adduct of a first moiety reacted in a first reaction with a second moiety to form the intermediate adduct. The intermediate adduct is esterifying or amidifying with a third moiety in a molar ratio from 1:2 to about 2:1. The first moiety is an unsaturated triglyceride plant oil or a thermal polymer thereof. The second moiety is a diene or conjugate double bond acid or anhydride moiety. The first reaction comprises mixing the first moiety with the second moiety in a molar ratio from 1:2 to 2:1, at a temperature from about 130 to 195oC under an inert atmosphere. The third moiety is a polyhydroxy or a polyamino compound. The fuel lubricity additive compound may be added to diesel fuel and kerosene that provides lubricity properties, improved combustion and improved emissions characteristics.
