﻿Hydrated Oxide of Ethylene-sodium. 361 



From which it follows that the percentage of sodium found in 

 the hydrated oxide of ethylene-sodium = 34'28. Theory re- 

 quires 33-82. 



The gain of HC1 is, in percentage, 



100 parts of product gain 159-97 of HC1. 



The theory for Na C 2 H 5 + HC1 is 



100 : 158-7. 



The resulting compound, Na C 2 H 6 CIO, breaks up between 

 100° and 150° into alcohol and hydrochloric acid; after heating 

 the above compound up to 200° C. it weighed 9218 grms., which 

 contain 3-5820 grms. of sodium. 



Chloride of Acetyl and Hydrated Oxide of Ethylene-sodium. 



These substances act very energetically, developing much heat. 

 Apparently the compound Na C 2 H 6 0, C 2 H 3 CI is formed. 

 On heating this compound above 100° C, it is resolved into 

 chloride of sodium and acetate of ethyle. 



Action o/CO 2 on Hydrated Oxide of Ethylene-sodium, 



It was a matter of interest to ascertain whether or not carbonic 

 acid and the hydrated oxide of ethylene-sodium would give lac- 

 tate of soda. Experiment in which the materials were brought 

 together at 180° C. showed that there is no formation of any 

 fixed acid. 



2*1 grms. of sodium were dissolved in absolute alcohol and sub- 

 sequently heated to 180° C. in a current of dry carbonic acid. 

 In this instance the product was not weighed, but treated with 

 water and subsequently distilled to drive off the aqueous alcohol. 

 The distillate, consisting of weak alcohol, measured 14*5 cubic 

 centims., and its specific gravity at 16° C. was 0-9670. It con- 

 tained therefore 3*48 grms. of absolute alcohol. The residue 

 left after the distillation of the weak alcohol was titrated with 

 standard acid. It saturated 91*5 cubic centims. of normal acid, 

 and therefore contained 2" 104 5 grms. of sodium uncombined 

 with any permanent acid. During the progress of the titration 

 the observation was made that the sodium was fully saturated 

 with carbonic acid. Collecting these data, 



Na taken =2-10 grms. 



Na found unneutralized . =2*1045 „ 

 Alcohol obtained . . . =3*48 „ 



No special care was bestowed on this determination of alcohol. 

 The close correspondence between the unneutralized sodium 

 after the experiment and that taken for experiment is demonstra- 

 tion of the non-formation of any lactate of soda during the action
