We calculate from the given acid values and fatty acid contents 



(table 4— 8) :

For the saponification of palmkernel oil with aqueous KOH 

 Kei.lner now gives the values of columns 1, 2, 3, and 6 of table 4. 



TABLE 4. 



It appears from columns 5 and 7 that (/ =: 1\ hence practically 

 /) = ^ = 00 (cf. § 11 and fig. 2 line A), in other words, there prac- 

 tically directly takes place splitting up into fatty acid and gljcerine. 



The values found by Kellner for the saponification of palm kernel 

 oil with lime are found in columns 1, 2, 3, and 6 of table 5,

Here too it appears on comparison of columns 5 and 7 that 

 g = T, and therefore p = q=^ oo must be practically valid also 

 here. It follows therefore from Kellner's experiments that in the 

 saponification of palmkernel oil with aqueous lye, as well as with
