The thermal reactions were carried out at 350470 C for 30 min using sodium palmitate (A) and an equimolar mixture of sodium palmitate and sodium hydroxide (B). The reaction products presumed to be formed by the reaction occurring in the vicinity of carboxyl group, particularly, pentadecane, 1-pentadecene, and 16-hentriacontanone (palmitone) were analyzed by capillary gas chromatography. <BR>1-Pentadecene was produced in much larger amount than pentadecane in the reaction of A. Meanwhile, the formation of pentadecane was predominant in the reaction of B, though the amount of 1-pentadecene increased with the elevation of temperature. The formation of palmitone, a condensation product of sodium palmitate with decarboxylation, was notable in the reaction of B. <BR>A possible scheme, in which sodium hydroxide plays catalytic role, was proposed for the formation of palmitone in the reaction of B.
