Abstract

The present invention discloses a single package additive for improving lubricity and conductivity properties of ultra-low sulfur diesel fuels. The single package additive is a reaction product of a fatty acid composition, a glycerol tricarboxylates, a polysulfone, a polyamine, an alkylated benzene sulfonic acid and a phenol derivative. More specifically, the present invention discloses a reaction product of: a fatty acid composition in the range of 60-95% wt/wt; a glycerol tricarboxylate in the range of 0.1-10.0% wt/wt; a polysulfone in the range of 0.1-5.0% wt/wt; a polyamine in the range of 0.1-5.0% wt/wt; an alkylated benzene sulfonic acid in the range of 0.1-5.0% wt/wt; and a phenol derivative in the range of 0.1-10.0% wt/wt. The present invention also discloses a single-pot process for the preparation of said reaction product.
