The results of hydrogenating pili-nut oil for various intervals 

 of time with different concentrations of catalyst are given m 

 Table 4. In these experiments the catalyst was very effective 

 and the oil absorbed hydrogen readily. 



The results show that, with each concentration of catalyst, 

 continued hydrogenation gave a gradual decrease in the iodine 

 value of the oil and an increase in the melting point. 



For each interval of hydrogenation, increase in the concen- 

 tration of nickel catalyst gave an increase in the melting point 

 of the oil and a very decided decrease in the iodine value. 

 Hydrogenation for ten hours gave with 0.5 per cent nickel an 

 iodine value of 41.69; with 1 per cent, 23.99; and with 3 per 

 cent, 3.91. Hydrogenation for fifteen hours with 3 per cent 

 nickel gave a sample having an iodine value of only 0.96 and 

 a melting point of 66° to 66.8°. In appearance the sample 

 was a hard white solid. Since oleic glyceride when reduced
