A mixture of 104 gms. (0.348 moles) of arachidyl alcohol, 46 gms. (0.362 moles) of benzoic acid and 225 mgms. stannous oxalate was heated under nitrogen to 230° C. The reaction was held at 230° C. for two hours under nitrogen. The acidity was 10 mgms. KOH/gms. The mixture was then cooled to 100° C. During the reaction distillate was collected. The ester formed was solid at room temperature and showed solidication at 80° C. The ester was given a treatment at 85° C. with 50 gms. deionized water containing 2 gms. sodium carbonate, 2 gms. sodium chloride and 1 gm. hydrogen peroxide. The mixture was allowed to stand and separate. The top layer was washed with 50 gms. deionized water at 80°-85° C., separated and cooled. The top layer solidified and bottom layer was completely drained off. The ester was then vacuum stripped at 100°-105° C. The ester so formed was a white solid benzoate.
