In order to settle this point, I exposed equivalent quantities of 

 these bodies in a sealed balloon to the temperature of a water-bath 

 for about two hours. My expectations, however, were not realized. 

 On opening the balloon, I found that the reaction had proceeded too 

 far, acetic ether having been formed along with the chloride of 

 sodium. 



Action of Hydrochloric and Butyric Acids on Glycol. Formation of 

 Chlorbutyrine of Glycol. 



This compound is prepared in the same manner as its homologue, 

 namely by transmitting a stream of dry hydrochloric acid gas 

 through a mixture of equivalent quantities of butyric acid and glycol, 

 maintained at the temperature of 100C. As soon as the reaction 

 is finished, the product is well washed with water, dried by means 

 of chloride of calcium, and distilled. The greater part passes over 

 between 160 and 182. This must be rectified, and the quantity dis- 

 tilling between 175 and 182 collected apart. This gave, on analysis,

Chlorbutyrine of glycol, as I may call this compound, has a pun- 

 gent and somewhat bitter taste. It boils at about 190. Its specific 

 gravity at zero is 1*0854. It is insoluble in water, but freely soluble 

 in alcohol. It is decomposed with difficulty by a boiling solution of 

 potash, but readily by solid potash, chloride of potassium, butyrate 

 of potash, and oxide of ethylene, being formed.
