Product 1

HCID 209817222-(1-Octen-1-yl)butanedioic acid

Procedure

Octenyl succinic anhydride was added to an aqueous, 45% potassium hydroxide solution, and heated to form the di-potassium salt of 2-octenyl-1,4-butanedioic acid (the friction modifier). A lubricant, methyl 9EO tallowate, and the friction modifier were mixed together to form a composition having a ratio of 9:1 by weight, respectively.
