IMPROVED METHODS FOR FAT ANALYSIS.

The derivation of the formula is comparatively simple. The theoretical 

 acetyl number of a compound containing d hydroxj'l groups is : — 



56108 d 



The amount of such'a compound in an oil, fat or wax is therefore — 



56108 d 



56108 d 



The same results may be calculated more easily from the following table 

 dividing the determined acetyl number by the theoretical acetyl number, or 

 multiplying by its reciprocal : —
