Propyl Formate. 



The results obtained with this ester can oiily be looked 

 upon as approximate, as the velocity of saponification is so great 

 as to be difficult to measure. The ester is decoinposed rapidly 

 in aqueous Solution, so that a departure was snade froui the 

 former iiiethod of raixing, 2 ccs of the pure ester being directly 



7t 



mixed with 100 ccs of — acid (HCl), according to the method 



of Ost WALD.
